WAGO - Who has not heard of the WAGO clamp, the WAGO terminal blocks, WAGO connection terminals or WAGO junction box terminals or the innovative WAGO Compact connection terminals of the WAGO 221 series? In particular, the transparent terminals allow a cable wire that has not been correctly inserted or not correctly stripped to be checked visually. High quality, practical and innovative. Everyone needs these clamps and most just want WAGO. But WAGO has much more to offer. eibmarkt® offers all top products from WAGO on eibabo®. In addition to the typical well-known items for electrical connection technology, WAGO also offers special electronic components for automation technology, such as the fieldbus-independent WAGO I/O system. WAGO Kontakttechnik GmbH & Co. KG is a German company. WAGO employs thousands of people worldwide. Two business areas separate the product range of WAGO, namely ELECTRICAL INTERCONNECTIONS and AUTOMATION. The ELECTRICAL INTERCONNECTIONS division was formed shortly after the company was founded in the 1950s. Among other things, it contained the first complete family of terminal blocks with self-supporting contact inserts. All WAGO electrical connection technology products are based on the principle of spring force. These clamping and connection systems guarantee trouble-free operation and 100% safety without any maintenance. Clamped easily and in a matter of seconds, and released again just as quickly if desired, WAGO's connecting, terminal blocks, printed circuit board terminals and connectors have proven themselves to be outstanding. Due to their reliability, they are ideal for use in building and energy technology, the automotive industry, traffic and process technology and in mechanical and plant engineering. In the 1990s, the ELECTRONICC division was added, which included the first fieldbus-independent WAGO-I/O-SYSTEM. Due to the rapid development, WAGO decided to adapt the name of the business area to the term AUTOMATION, which is more common on the market. The WAGO AUTOMATION division offers customers flexibility and planning freedom as the main advantages of modular and fieldbus-independent devices in decentralized automation. In this area, WAGO introduced a fieldbus system as early as 1995 with which fieldbus nodes can be precisely adapted to an application using the modular principle. Since then, this system has been continuously expanded and further developed. I/O systems, interface modules, power supplies and overvoltage protection from WAGO are used wherever maximum performance and 100 percent safety are required: in industry, process technology and building automation just as naturally as in all safety-relevant and potentially explosive areas. At eibabo® you will find a variety of items in the main catalog for electrical material in the plug-in terminals, lighting terminals, terminal blocks, test measuring devices, function modules and relays catalogues. With over 1500 items, eibabo® offers a large selection of high-quality products from WAGO, with which you too can implement your projects flexibly, safely and quickly. In particular, our approx. 500 WAGO stock items are very popular.

Small room fan - Are you looking for products and information on efficient living space ventilation? Then you are exactly right in our shop. We present our high-quality and inexpensive small fans and give you tips on how to use them. Modern houses are particularly well insulated in order to save heating energy costs. Passive houses in particular are almost airtight. Nevertheless, it is important that stale air gets outside and fresh air gets into the building. Moisture and pollutants must be removed to avoid mold growth or other structural problems.Small room fans also include bathroom fans, ceiling fans, pipe fans or window fans. Increase living comfort, improve the indoor climate and remove unpleasant odors. In our shop you can get small fans for your building, with which you can breathe really well at home and in the company. By installing a high-quality small room fan for controlled living space ventilation, you improve the air quality. If necessary, the device vents automatically. You don't even have to be there for this. This contributes to well-being without having to forego the advantages of good thermal insulation.Image: Helios HR 90 KEZ mini fanWhat is a small room fan?Appropriate indoor air quality is crucial for the well-being of residents. New buildings nowadays are equipped with good insulation. As a result, stale air cannot escape from the building by itself. Air pollution and excessive CO? concentrations have a negative impact on the building and the health of the people who live and work in it. In addition, compliance with certain air parameters is important for the fulfillment of many industrial manufacturing processes, storage methods and ripening processes. The best way to ensure continuous air exchange is to open windows and doors. If this is not possible due to the structure of the building, the weather or the time of year, fans, ventilation systems or air circulation systems must be used.Simply put, small room fans are electrical devices that set the air in motion and usually transport it out of the building. The fans are installed in and on wall ducts or inside ventilation ducts.Where are small room fans used?In the living area, the devices offered are suitable for decentralized ventilation in the bathroom and toilet, in the kitchen and in damp rooms, storage rooms and pantries. For commercial and industrial companies, high air quality is an essential component for the realization of comfortable operational processes. The quality of a service, the production processes and the productivity of the employees depend directly and indirectly on it. The choice of the right device and its capacity must be tailored to the requirements of the respective place of use. Various small room fans are quick and easy to install and are usually suitable for both wall and ceiling mounting.Please noteSmall room fans are mainly only intended for ventilation or dehumidification of a room and do not replace a ventilation system. Supply air systems as well as exhaust air systems are usually present in a room. When using separate devices, their performance must be balanced, otherwise negative or positive pressure will be generated.In the case of structural restrictions, rooms can also only be equipped with an exhaust air system. The supply of fresh air must then be ensured through special openings or connections to other rooms. You can also get a high-quality ventilation system for the complete exchange of room air here in your eibabo® shop.Which functions can be implemented with small room fans?You can implement various control options with a small room fan: The fan can be switched on together with the light in the room, and the fan is often combined with a relay for follow-up control, interval control or time control. With sensible control, your small room fan works optimally and demand-controlled as well as energy-efficiently and economically. Of course, simple small room fans can also be operated with just one switch. TIPFor the installation of small room fans you need a power supply and they are usually installed in an outer wall and above head height. Some models are designed in such a way that they still offer convenient control functions without barriers and independent of external installations. These then have integrated operating programs that can be set directly on the device. For example, choose from comfort programs, night programs, economy programs and power programs. Or the fan offers automatic switching on and off via humidity sensors.How do I determine if I need a fan for ventilation?Basically, efficient ventilation ensures a constant exchange of air within a building. Ideally, this happens by itself due to small leaks or you support this by regularly opening windows and doors. If the removal of used air is impaired and an increased carbon dioxide and water vapor content occurs, this affects our well-being and may lead to structural damage. The most common signs of insufficient ventilation are:high dust content in the airhigh humidityoccurrence of verminfrequent headaches and increased fatigueIrritation of the mucous membranes of the nose, mouth and throatdiseases of the respiratory tractarise from allergiesfungus and mold growth Carbon dioxide is not only found in the air we breathe, but is also released from appliances, stoves, fireplaces and boilers. Combustion processes produce harmful and toxic substances such as carbon monoxide. If combustion processes take place in your house, you should definitely ensure sufficient air exchange. Excess water vapor from the air you breathe, in bathrooms, saunas or laundry rooms can dampen the walls. This promotes the growth of fungi or mold.What performance should a small room fan have?The calculation of the performance of a small room fan depends on various parameters. While the project planning for larger ventilation systems should be carried out by an experienced installer, the following is sufficient for estimating the performance of a small room fan:the consideration of the room area or the volume of the premisesthe assessment of the extent of air pollution A fan with a capacity of 200 to 350 m³/h extracts the air in a living area of 30 to 60 m². A capacity of 350 to 500 m³/h is designed for an area of 70 to 130 m². Reserves due to certain cable routes and architectural features are already taken into account. TIPRemember that the air extracted by the fan must be returned to the building or room by a different route than fresh air. Alternatively, you can determine performance based on the number of people typically in the room. In this case, assume around 60 m³/h per person, in quiet rooms such as bedrooms this value can be reduced to 40 m³/h.What should be considered when buying small room fans?The choice of the right small room fan depends on the place of use and the function you expect. The most important selection criteria include:Size of the device or, in the case of built-in devices, the pipe diameterPerformance in m³/hVolume (pay attention to ball bearings and freedom from maintenance)Assembly / installation on-wall or flush-mountedpower supplyColor scheme to match the interiorIP rating for contact with dust, dirt and moistureBarrier-free operation, with a switch or integration into the home networkAbility to control speed or choose power levels At eibabo® you can get small room fans, mini fans, inline fans or even fans with overrun at top conditions.

Electricity meters - Have you always wanted to know how much energy individual devices in your household consume? This catalog from the eibabo® shop offers you the right measuring instruments for this. Here you can get high-quality electricity meters and many other meters at top conditions. In our modern home we use numerous electrical devices. In addition to lamps, washing machines and refrigerators, media technology is a major energy consumer. Televisions, computers, chargers for smartphones and building automation are powered by electrical energy. Although some of these devices also help save electricity, it is interesting to know how much energy they actually use.What are electricity meters?Electricity meters are devices for displaying electricity consumption or energy consumption in electrical systems. AC induction meters are predominantly used in households, which directly display the consumed kilowatt hours. To find out how high your energy consumption is in a certain period of time, you need to take two measurements. Subtract the value of the second measurement from the value of the first measurement.Image: ABB B23 113-100 three-phase meter M-BusWhat types of electricity meters are there?There are two main types of electricity meters. These are used by the utility companies. On the one hand there are the electromechanical meters and on the other hand the so-called intelligent meters or smart meters. If you operate a solar system and feed electricity into the grid, you need a third type of meter, the bidirectional meter. These measure the current drawn and the current fed in. As a rule, you have little influence on the electricity meters that come from your energy supplier. These are installed where the power lines enter your building. This catalog is about electricity meters, which you can also install. This allows the consumption of a specific section of your installation or the consumption of an individual end device to be measured.How is an electromechanical meter constructed?Electromechanical induction meters are widely used and can be found in many homes. These contain an electrically conductive, non-magnetic, rotatable 'Ferraris disc'. The disk is driven by the interaction of magnetic fields generated by two electromagnets.Magnet 1 is powered by the current from the incoming power linesMagnet 2 is powered by the current demanded by the building's electrical circuits The rotation of the disk is slowed down by two permanent magnets, which exert a proportional opposing force. The aluminum disc drives a scrolling mechanism that displays kilowatt hours or fractions thereof.How does a smart meter work?Electronic electricity meters have been on the market for several years. The current standard for electronic electricity meters are digital electricity meters and so-called smart meters. These work in a similar way to electromechanical electricity meters. Instead of mechanical moving parts, they contain a battery and a communication chip. The chip sends meter readings wirelessly to a collection point. This happens several times a day depending on the time of day. The data is usually transmitted to the electricity supplier every quarter of an hour via power lines, mobile communications or high-frequency networks. Already knew?The chip is also known as an encoder or ERT device. This uses the same frequency as many cordless phones. However, the device is designed to avoid interference. The battery in the communication chip in digital electricity meters is designed for a service life of 15 to 20 years.What are the advantages of measuring with an electronic electricity meter?With an electronic electricity meter, you can not only determine how much energy you use, but also when. At first glance, this may be less important additional information. But knowing exactly when and how much electricity you are using can save you a lot of money. Electricity prices vary throughout the day. When demand is high, electricity costs more than when demand is low. Constantly rising energy costs are leading to deregulation of the electricity markets. In the future, utilities could offer electricity tariffs that bill for the electricity provided based on the time of use. This would be a significantly fairer billing method than the current variant, which is based on average costs.smart gridSmart grids are intelligent power networks that take generation, storage and consumption into account. This allows fluctuations in power in the network to be compensated. Networking and coordination is carried out using modern technologies and decentralized energy management systems.Smart meters can also be read remotely. Utility companies thus save operating costs and working time. Electronic electricity meters are therefore an essential part of the so-called smart grid. The devices help you to question your habits and save money if you use your electricity off-peak. Think of buying an electronic electricity meter as an investment in your future.How do I find the right electricity meter?Modern electricity meters can be used to display electricity consumption in real time. Especially in the KNX area, intelligent electricity meters offer many advantages. These support you with load management within your installation and with the monitoring of services and end devices. This saves you money and time because you can make adjustments according to your consumption profile. The use of data loggers or programmable logic controllers makes it easier to display, control, analyze and monitor the data. You can integrate models with a KNX interface directly into your building automation system using Engineering Tool Software (ETS). But which things are still important when buying?number of phasesWhen choosing an electricity meter, please consider how many phases are required. The most common models are single-phase or three-phase. If your current system that you are getting your data from is single phase, you will need a single phase electricity meter. If the electrical system is three-phase, use a three-phase electricity meter. As a rule, the devices can be mounted on a DIN rail. The measurement is carried out flexibly for various performance parameters such as:True RMS Voltage (Vrms)True RMS Current (Irms)Active power (kW)Active energy (kWh)Apparent Power (kVA)Apparent energy (kVAh)Reactive Power (kVAR)Reactive energy (kVARh)Power Factor (PF)frequency The devices can be used both on the primary side of the low voltage and on the secondary side of the medium voltage and high voltage.The ampPay attention to how many amps you need for the system. Commonly, smart electricity meters support 60 amps, 100 amps, and 200 amps. The right choice depends on your power system. Using a 100A electricity meter for a system that requires 200A would be impractical.Bus systems and networksIntelligent electricity meters communicate via various media and protocols. Please determine in advance which communication protocols will be used. Well-known fieldbus systems are AS-Interface, CAN, CANopen, M-Bus, EtherCAT and others.

Frequency converter = - Do you have an AC motor and want to control its speed? Then the use of a frequency converter is an interesting product for you. A frequency converter is always used when you need permanent speed control on a machine. This can be, for example, pumps or compressors, but also fans, mixers or mills with electric motors. A frequency converter converts the fixed mains voltage into a variable voltage. This enables not only operation of the motor at a constant speed, but also acceleration and deceleration. In this way, the speed of a machine can be adapted to the current work requirements, energy can be saved if necessary, or production processes can be varied over time.Use the high-quality frequency converters from the eibabo® shop, protect materials with speed control and thereby extend the service life of your machines. Manufacturers of high quality goods are ABB, Eaton, KEB Automation, Maico, Mitsubishi, Omron, Rockwell, Schneider Electric and Siemens.What is electrical frequency?In order to explain electrical frequency and to be able to deduce the function of a frequency converter, we must first look at the basics of electricity generation. There is direct current and alternating current. Direct current always flows in one direction. Alternating current periodically changes direction. This change is represented in a diagram in the form of a sine wave, which is alternately in the positive and negative area of the zero point. Accordingly, an alternating voltage is also an oscillating electrical voltage.Already knew?The Danish company Danfoss was the first company to start series production of frequency converters. This was in 1968.The AC frequency describes the number of cycles in this sine wave per second and corresponds to the number of changes in direction. This is given in Hertz (Hz). 1 Hertz corresponds to a complete cycle from the zero point to the positive range, to the negative range and back to the zero point. The more cycles per second occur, the higher the frequency. The usual mains electricity in Germany and Europe has a fixed frequency of 50 Hertz.How does a frequency converter cause a change in motor speed?The standard speed of an AC motor is tuned to a specific frequency. This is based on the structure of the respective motor. A constant magnetic field with stationary poles prevails between two field magnets. Within this magnetic field is a rotating, also magnetic 'anchor' with two poles. If alternating current is passed through the armature, its polarization changes in time with the alternating current. With a mains frequency of 50 Hz, this happens 50 times per second. Accordingly, the attractive and repulsive forces between the field magnet and the armature change direction 50 times. Once set in motion, this alternation ensures a certain rotational movement of the armature and speed of the motor. Each change in frequency therefore also causes a proportional change in motor speed. The frequency converter is responsible for changing the frequency.The advantages are:infinitely variable control of the desired nominal speedReach very high and very low speedsdirect switching of the direction of rotation Picture: Schneider Electric ATV320U22N4C frequency converterWhat are the reasons for a change in engine speed?An almost constant frequency is applied to the classic AC network and therefore only one speed is available to you. The frequency converter regulates the frequency and voltage of the power supplied to the motor. That is why this device is often also called a speed controller. There are many reasons why the engine speed needs to be adjusted:to save energy and increase efficiencyto optimize the flow of manufacturing processesto protect material and extend the service life of machinesto meet the requirements of processing various materialsto adjust the torque / power of a driveto lower the noise levelto reduce peak loads Modern frequency converters have network and diagnostic functions. This makes it possible to integrate the devices into the control system of a plant and to monitor and optimize all processes.Where are frequency converters used?Frequency converters are used in numerous industries and applications. These devices are mainly found in compressor, pump and fan drives. But the speed of conveyor belts, production lines or cranes can also be controlled with frequency converters. An adapted or infinitely variable speed enables energy-efficient and optimized production processes.What should be considered when buying a frequency converter?The correct selection of the frequency converter is crucial for the optimal operation of the corresponding devices. Before selecting the drive, determine the number of input phases. Will the device be three phase or single phase? Will the device handle resistive loads, inductive loads, capacitive loads, or mixed loads? The individual loads cause different inrush currents when starting. Please consider this. Before you buy, find out about:the requirements of the operating environmentthe starting torquethe load torque characteristicsthe speed control range and the static speed accuracy TIP:You are very flexible with regard to the location. Frequency converters are available for installation in the control cabinet, for wall mounting and for decentralized field use. Since a certain level of expertise is required to evaluate these properties, we recommend consulting an experienced electrician.

Heating actuator - A comfortably warm bath after getting up or a cool bedroom at night - automatically. Who does not want that? Modern building automation makes it possible. The interaction of room temperature controllers, heating actuators and valve drives offers almost unlimited possibilities. The setup can be set up in all rooms according to the needs of everyday life.What are heating actuators?If you want to regulate the temperature in the room, in the apartment or in the entire building automatically, heating actuators play a central role. In principle, these are switching actuators. However, these are not equipped with mechanical relays. Thermoelectric valves (low ohmic loads) work here, which use electronic circuits (Triac) to ensure closed hot water circuits or chilled water (chilled ceiling). As a result, these devices are noiseless and wear-free.How is room temperature controlled via a heating actuator?The control difference determined by a KNX room temperature controller, i.e. the difference between the setpoint temperature and the actual temperature, is converted into a command value telegram. It is sent to the corresponding channel of the heating actuator via the KNX bus. Connect the thermoelectric (conventional) actuator to the duct using a suitable cable (e.g. NYM-J 3x1.5). The heating actuator can switch directly (1 bit) or independently process a received 1-byte command value signal internally. With the latter, the KNX bus is relieved because there is no flood of control telegrams from the room temperature controller to the actuator. Only the calculated control difference is sent to the actuator as a 1-byte command value telegram (0-100%). This converts the information into switching signals (on/off) directly to the assigned heating channel. This is called pulse width modulation (PWM). TIP:Make sure there are enough control channels on the heating actuator, ideally at least one per room. This creates maximum flexibility when controlling. The following small example illustrates the rough functionality, not the actual, manufacturer-specific control algorithm:The current temperature (controlled variable) is 20 degrees Celsius. The desired room temperature is 25 degrees Celsius and represents the set value for the controlled variable (command variable). The difference between the desired room temperature (set value) and the current temperature (actual value) is the control difference. The control difference is 5 degrees Celsius and is used to determine the manipulated variable that influences the room temperature. Assuming the manipulated variable is 20%. This value is sent to the heating actuator in the form of a 1-byte telegram (0-255 = 0-100%). The value 51 is therefore transmitted to the actuator. The time for opening/closing the actuator is stored in the parameters of the actuator using ETS. You can find this time in the properties of the respective 230V AC or 24V DC thermoelectric actuator. For example, the actuator takes 2 minutes to fully open. With a command value specification of 20%, the actuator would switch on the valve drive for 24 seconds (20% of 2 min.) and switch it off for 96 seconds. This process is repeated until the room temperature controller calculates and sends another command value specification. Depending on the manufacturer of the actuator, you can integrate several actuators per channel.How do I find the right heating actuator?The selection of a suitable heating actuator is linked to certain requirements. Answering the following questions will help you make a decision:How many heating circuits does my system have?How many actuators do I have per heating circuit?Do I want to install the heating actuator centrally or directly in the heating circuit distributor?Do I want to protect the power supply of the device via a connection for auxiliary voltage?With what voltage do the actuators work?Which functions should the heating actuator have?Do I prefer a certain brand?and many more The range of functions of a heating actuator in particular can differ depending on the model. Things to keep in mind include the following:Is it controlled with 1bit (switching/PWM) and/or 8bit (continuous) control values?Is direct control with a temperature value possible via the KNX bus?Does the device have an integrated temperature controller?Are the setpoints saved in the event of a bus voltage failure?Is there an emergency operation if the cyclic command values fail?Are different operating modes available (comfort, night, frost protection, summer mode or winter mode)?Is there a short-circuit detection and a voltage failure detection?Does the device have a pump shut-off? High comfortDepending on the model, it is possible to set a minimum comfort temperature for the underfloor heating. An additional sensor measures the temperature of the floor and keeps it at your comfort level. This is very pleasant in barefoot zones such as a bath.Depending on what value you place on the individual properties, the range of products can be limited to just a few models.Can I connect a heating actuator directly to the actuators in my heating circuits?In the case of a decentralized installation, for example in the heating circuit distributor, models with L and N connections can be used for direct connection of the actuators.Are KNX actuators really bad?Thermoelectric actuators are not wear-free and should be replaced every year. That is why expensive KNX actuators, which combine the KNX actuator and actuator, have not caught on and are disappearing from the market.Image: Jung Triac 2336-REG-HZR-HE 6-fold KNX heating actuatorHow are thermoelectric actuators installed?Thermoelectric actuators (valve drives) are snapped or screwed directly onto the upper part of the valve used in the house. This connection with the valve spindle is usually made directly in the heating circuit distributor. You can use adapters made of PVC or metal to compensate for the manufacturer-specific distance differences between the drive and the upper part of the valve or the thread and the mount. In this way you ensure correct implementation of the manipulated variable.How do I prevent rapid wear and tear on my valve drives?The ETS parameter 'Flush' minimizes wear and tear on valves that are rarely used, for example in summer or in bedrooms. This function prevents rapid calcification of the heating valves. Good to knowWith actuators, a distinction is made between NC (normally closed) and NO (normally open). NC drives open when power is applied. In NO actuators, the current closes the valve. Please bear this in mind when planning your heating system, as it is ultimately your personal decision. In the event of a power failure or defect, NC drives close and you quickly notice a malfunction. These drives only consume electricity when heating. On the other hand, drives that open without current are more efficient during the heating period. In this case, switching off the pump by the heating actuator after the winter season would be advisable. Otherwise you would continuously use electricity to keep the heating closed by means of the NO actuators in the warm season.Who are the leading manufacturers of KNX heating actuators?The leading manufacturers of KNX heating actuators at eibabo® are, for example, ABB, Berker, Busch-Jaeger, EIBMARKT, Elsner, Gira, Hager, Jung, Lingg & Janke, MDT, Merten, Siemens and Theben. We have more than 25 years of experience in the field of building automation and have arranged the order of the products in this catalog accordingly.

Logic module - What is a KNX logic module and what options does the device offer when linking simple and highly complex functions? Why do we recommend logic modules as a useful addition to any KNX system? Find out here.KNX is the standard protocol for smart home and building automation. A system equipped with KNX technology enables you to control all connected devices in your household via a touch panel or remotely. The KNX technology is used not only in private homes or shops, but also in industrial buildings, hospitals, schools, high-rise buildings, universities, yachts and ferries and other facilities. The KNX automation system in residential or industrial buildings connects a large number of devices within the same facility. This allows information to be exchanged very quickly and maximizes efficiency in the workplace. There are hardly any limits to the size of a system and its complexity. KNX can be connected to different systems like BACnet, LON, LCN, RS485, LoRa, NB-IOT, Zigbee and others. This creates almost unlimited possibilities. Changes and extensions are possible at any time, quickly and inexpensively. The KNX automation makes our life more comfortable because it is:flexible - Almost all functions in the house can be controlled via KNX. Numerous brand manufacturers offer a wide variety of compatible devices.User-friendly - All electrical devices are easy to control. All control modules can be operated manually.safe and secure - the KNX system is not based on 230V, but on harmless 24-30 V. With the KNX Secure function, the system is particularly secure. With the KNX technology, the house, property and outbuildings can be controlled and monitored automatically. The use of additional control centers is not necessary. The KNX system fulfills a large number of functions, for example lighting, air conditioning and security systems. Work steps and daily routines are accelerated and the energy in our living space is used more efficiently. Easy installation:As series installation devices, logic modules are quickly clamped onto the DIN rail. The KNX connection is made using a special terminal. In order to create a perfect setup, numerous primary and secondary components can and must work together in a system. This includes KNX logic modules. These are always used when the installed KNX devices lack the necessary logic functions for specific tasks or higher-level central control and regulation tasks are required. As a modular installation device with a width of 1 to 2 modular widths, logic modules and scene modules/event modules also fit into small installations. An additional power supply is not necessary. The device draws its energy from the KNX system.What are KNX logic modules used for?KNX logic modules are a very useful and important addition to any KNX system. This means that additional functions can be reliably mapped. With the help of KNX logic modules, you can define a wide variety of dependencies and logically link group addresses. It is possible to implement simple and highly complex functions, from the alarm system to meter monitoring. You always remain decentralized and independent of central server components.Image: MDT SCN-LOG1.02 logic moduleKNX logic modules offer linking functions with:all common logic gates, filter functions, time functionsTime modules with comparison function and run-on timeconverters and multiplex modulesdelay blockslight scene modulesMonitoring functions of bus participantscomplex specific blind controlshour counterstemperature switches or temperature modulesConverters for converting telegramsSequencer modules for generating multiple telegramsand many more TIPEven if a KNX server/visualization is used, we recommend a KNX logic module for failure monitoring or for relevant functions that must be ensured in the event of a KNX server failure.You are still not sure what practical use logic modules have? We will show you with a very simple example:Suppose you have a small pond with a fountain on the patio of your house. Now you want the fountain to be running when you are home in the evening. The easiest would be to turn it on and off manually. No automation is used here. Using a timer is a bit more convenient. This means that the fountain runs in the evening after work, for example from 5 p.m. to 9 p.m. However, this is not yet intelligently automated. If the fountain's power supply is connected to the KNX bus, you could set the switch-on time in the evening and let the fountain run until sunset. But what if you sit longer on your terrace at the weekend and don't want the fountain to switch off when the sun goes down. This is where the logic module comes into play. In addition to timing and sun control, you can now command the fountain to keep running as long as the patio lights are on.How are KNX logic modules programmed?The KNX logic module is usually parameterized via the ETS (Engineering Tool Software). Complex KNX logic modules are processed using a simple graphic editor, which also enables laypersons to easily program and commission them. These logic modules often require free additional software/plug-in provided by the manufacturer.Are there different KNX logic modules?eibabo® has a large portfolio of KNX modules that are designed for a wide variety of tasks. These include KNX logic modules, KNX logic building blocks, KNX security modules, KNX application building blocks, KNX time building blocks, KNX logic controls, KNX link building blocks, KNX monitoring building blocks, KNX function modules, KNX scenes/event building blocks, KNX visualization servers and KNX logic controllers. When buying, make sure you choose high-quality goods from manufacturers such as ABB, Berker, Buderus, Busch-Jaeger, Hager, Jung, MDT, Merten, Schneider-Electric or Siemens.

Ventilation unit - Clean and fresh air in your home: You can find products and information on efficient living space ventilation here. We will introduce you to our high-quality and inexpensive ventilation units and give you tips on how to use them optimally. In order to save on heating energy costs, modern houses are particularly well insulated. Passive houses in particular are almost airtight. Nevertheless, it is necessary that stale air can get outside and fresh air can get into the house. Moisture and pollutants must be removed, otherwise mold will form or other structural problems will occur.For trade and industry, the installation of ventilation is not just a basic standard for comfortable operational processes. The perception of a company in the service sector, the quality of the production processes and the productivity of the employees depend directly and indirectly on the indoor air quality. It is necessary to choose the type and capacity of the facility in accordance with the needs of the enterprise.So that you can breathe deeply at home and in the company, you can get ventilation units for your building in the eibabo® shop. With a high-quality system for controlled living space ventilation, you can filter and improve the air quality. Even if nobody is on site, such a system ventilates completely automatically. This contributes to well-being without sacrificing the benefits of good insulation.What is an air handling unit?Appropriate air quality in a building determines the well-being of its occupants. New buildings are now well insulated and stale air cannot escape from the building on its own. Polluted air and an excessively high CO? concentration have a negative effect on well-being. Compliance with certain air parameters is also necessary in many industrial manufacturing processes, storage methods and ripening processes. Therefore, a continuous exchange of air is particularly important. The best way to do this is to open windows and doors. However, if this is not possible due to structural conditions, the weather or the time of year, ventilation devices or room air systems are used.Simply put, air handling units are fans or blowers that move air. Simple ventilation devices are mounted in wall ducts and can take on different functions. As a supply air system, a ventilation device ensures that fresh air is supplied to the room. Depending on the model, the supply air can be cleaned, heated or humidified. As an exhaust air system, such a device removes the exhaust air from the room. Both supply air systems and exhaust air systems are usually present in a room. TIP:When using separate devices, their performance must be balanced, otherwise negative or positive pressure will be generated. In the case of structural restrictions, rooms can also only be equipped with an exhaust air system or only an air supply system. The supply of supply air or the disposal of exhaust air is ensured through special openings with other rooms. In these cases, combined devices represent interesting alternatives. They fulfill both tasks, are compact and available in different performance classes. Depending on the arrangement and performance, a ventilation unit can be used for point ventilation (e.g. for a workplace) or as general ventilation for an entire room.In this eibabo® shop catalogue, you will also find room air systems with central air exchange control. These usually have heat recovery and a high delivery volume for several rooms or an entire building. When using a central ventilation system, the installation effort is higher because ventilation shafts have to be routed from the control center to all rooms. This is usually only possible during the construction of the building or during extensive conversion work. Subsequent installation could not be installed within walls or ceilings and would remain visible.How do I know I need extra ventilation?Efficient ventilation guarantees a constant exchange of air in the room. Ideally, a building regulates this independently through small leaks or you support this by regularly opening windows and doors. If this exchange is interrupted, an increased level of carbon dioxide and water vapor affects our well-being. The most common signs of insufficient fresh air supply are:Irritation of the mucous membranes of the nose, mouth and throatdiseases of the respiratory tractfrequent headaches and increased fatiguearise from allergiesfungus and mold growthoccurrence of vermin Carbon dioxide is not only found in the air we breathe, but is also emitted from appliances, stoves, chimneys and boilers. Combustion processes produce harmful and toxic substances such as carbon monoxide. If you have any combustion processes in your home, be sure to ensure good ventilation. Excess water vapor can wet the walls, encouraging the growth of fungus or mold.Image: Glen Dimplex DL 50 WE2 decentralized ventilation unitWhere should ventilation units be installed?Depending on the type and scope of a system, the place of use must either be selected according to need or already determined during the construction phase of a building. For single fans you only need a power supply. They are usually installed in an outside wall and above head height. Classic rooms are bathrooms, toilets and kitchens. If you deal with fire (welding equipment), paint (fumes) or engines (exhaust gases) professionally or in your free time, then we recommend ventilation units in the relevant garages and workrooms.If you envisage a central ventilation system when constructing a building, please consider the function of the individual rooms and the frequency of use. In this way, sufficient aeration points and venting points can be provided at the appropriate points. These are then also above head height, usually built into walls or ceilings.What performance should a ventilation unit have?The calculation of the performance of an air handling unit or ventilation system depends on various parameters. At least for larger systems, the project planning should be carried out by an experienced installer. For apartments or individual rooms, however, you can select a system or model based on the total area or volume of the premises without complex calculations. As a rough guideline: They exchange the air in a living area of 30 to 60 m² with a capacity of 200 to 350 m³/h. A capacity of 350 to 500 m³/h is designed for an area of 70 to 130 m². Reserves due to certain cable routes and architectural features are already taken into account. Alternatively, you can determine performance based on the number of people typically in the room. In this case, assume around 60 m³/h per person, in quiet rooms such as bedrooms this value can be reduced to 40 m³/h.What is the difference between ventilation and air conditioning?Ventilation and air conditioning systems improve air quality. However, the systems do not replace each other, they complement each other. Ventilation removes used air and brings fresh air into the room. The air conditioner cools and circulates the air in the room. The air conditioner does not supply fresh air to a room and does not extract polluted air. However, many models improve other air parameters by changing the temperature or humidity or by cleaning the air using filters.save energyBoth systems should not run at the same time. Otherwise, the operating costs of the air conditioning system will increase due to the constant flow of uncooled air through the ventilation.In combination, however, both installations have a positive effect on the premises. Proper use can significantly impact health and well-being and improve quality of life.What should I look out for when buying a ventilation unit?It doesn't matter whether you choose a single unit or a ventilation system. In any case, there are a few basic things to look out for when making a purchase. These include:The performance - Does the flow rate correspond to the desired volume of air to be exchanged in a certain period of time?The power supply - Can I provide the necessary power supply at the appropriate installation sites?Energy efficiency - Does the device work economically and is long-term operation economical?The noise development ? What noises do the respective devices generate and could they be disruptive?The equipment ? How are the microclimate or the heating costs influenced by filters, heat exchangers or humidifiers?The look ? Can a ventilation unit be installed discreetly or does it bother me to look at it?Maintenance ? What are the follow-up costs for maintenance, repairs and filter changes?
