Blind actuator

How can I automate my shutters and blinds? Can the time of day, the weather and the position of the sun be taken into account? We provide recommendations and information on the purchase of KNX blind actuators and show you what options the technology offers you in everyday life.

If you want to build a new house or renovate an existing building, many questions arise. The technical equipment in particular must be well thought out, because a later change is then only possible with a lot of effort. If you already include the advantages of intelligent building automation in your planning, then the opening, closing and shading of the windows will also play an important role.

Useful application examples for controlling blinds or roller shutters:

  • the up and down of roller shutters and blinds according to time specifications
  • turning the slats of blinds based on the brightness in the room
  • the automatic opening of roller shutters or blinds when windows are opened
  • the simultaneous operation of several shading systems
  • the flexible control or regulation of the roller shutters when you are absent via a smartphone app
  • the automatic drive to the safety position in the event of a storm alarm and back after the all-clear
  • the blocking of operation for certain people
  • automatic shading according to geographic location and position of the sun (astro control)

 

The use of modern KNX blind actuators supports you in realizing all these projects. They ensure more security, greater comfort and increase the value of your property.

What distinguishes a KNX blind actuator from a KNX switching actuator?

All motorized equipment such as blinds or roller shutters can be automated using KNX blind actuators. Standard 230V blind actuators therefore have 2 channels per switching output. A channel to drive up and a channel to drive down. The channels are mutually locked to prevent damage to the drive. So only one phase can be switched through to the drive at a time, never both at the same time.

 


TIP:

Never use KNX switching actuators to control blinds and shutters without a downstream isolating relay.


 

With classic KNX switching actuators, the channels are not mutually locked. It would therefore be possible to connect more than one phase to the drive. This can quickly lead to damage to the technology. There are models which, depending on the configuration, can be used both as a switching actuator and as a shutter actuator. Please read the specification of the respective actuator.

What should be considered during installation?

Motorized 3-point drives must not be connected in parallel. Group formations may only be carried out using isolating relays or group control devices if the manufacturer does not provide for any isolating function. For example, for 4 windows, each with a drive, you should use a KNX blind actuator with 4 channels. There is also the option of operating several drives via one channel using conventional isolating relays. The shutter actuator channel then controls the isolating relay and the drives are connected to the isolating relay. In the meantime, however, the prices for the KNX actuators have fallen massively, so that there is hardly any need to reduce costs by using isolating relays.

 


TIP:

When selecting your components, always prefer one blind actuator channel per blind motor.


 

For example, if you would like to integrate 6, 8 or 12 blinds into your system, you will find the appropriate actuator here in the shop.

Are blind actuators with 230V AC better than models with 24V DC?

This question is not about better or worse. Rather, the type of voltage of the drives should always be considered. The drives of blinds or roller shutters are often designed as 230V AC (alternating voltage) or 24V DC (direct current). That's why you have to buy the matching blind actuator or roller shutter actuator. A 24V DC blind actuator or roller shutter actuator has a plus and a minus connection. A suitable KNX actuator generates the direction of travel (up/down) by changing the poles (pole reversal).

Do shutter actuators require a separate power supply?

The 24V DC mains supply is not provided by the actuator and must also be installed externally depending on the power requirement for simultaneity (central commands). In this case, very large power supply units can become necessary, which, in addition to high costs, also require a large amount of space. If you can, order 230V AC drives and matching 230V KNX blind actuators from the supplier. These also require their own power supply, but no additional power supply units.

That is the reason

So-called monostable relays are installed in the shutter actuators, which are open and not active when idle. However, the relays continuously require energy as long as they are closed (e.g. for the duration of a blind movement). The bus voltage alone cannot cover this requirement.


In contrast, there are bistable relays in classic switching actuators. These only require some energy in the brief moment of switching from one position to another. This can be implemented via the bus and an additional power supply is usually not necessary.

What do I need an SMI KNX blind actuator for?

SMI stands for 'Standard Motor Interface' and is an intelligent, uniform and manufacturer-independent interface in building automation. This is used to connect various operating resources, such as window drives, roller shutter drives or blind drives to a higher-level building management system. There are SMI KNX blind actuators for drives with an SMI interface. These intelligent drives are therefore able to exchange data telegrams across manufacturers.

Which actuators are recommended for controlling roller shutters and blinds?

eibabo® carries KNX blind actuators, KNX roller shutter actuators and KNX SMI actuators from ABB, Berker, Busch-Jaeger, Gira, Hager, Issendorf, Jung, Lingg & Janke, MDT, Merten, Siemens, Somfy, Theben, Warema and many other manufacturers.

1-byte communication object - what is that?

In any case, make sure that your blind actuator or roller shutter actuator has a 1-byte communication object for the runtime and slat, in order to be able to enable automatic or targeted control if required.

There are no slats in roller shutters, which is why roller shutter actuators do not have the slat communication object, only Up/Down/Stop. Roller shutter actuators often have a 1-bit object for a defined positioning movement that can be set via the ETS software.

1 byte means that values between 0-255 can be approached, which correspond to 0-100% related to the travel time. The parameters often allow the running time to be set according to the driving time. The travel time of the blind or roller shutter is entered once in the actuator using the ETS software, namely for a complete opening or closing for each channel of the actuator. There are also actuators for evaluating limit switches, which the motorized drive provides.

The extensive application of the KNX blind actuator / roller shutter actuator JA.6.230 from Eibmarkt® shown here enables a wide range of parameterization via the communication object, including scenes for runtime and slats, blocking functions, automatic functions, security functions and alarm functions, movement limitations, position feedback and much more.

Can a layperson use the ETS software to program the KNX devices?

Don't be put off by the term 'programming'. The ETS software is only used to assign and parameterize certain actions. Programming skills or learning a programming language are not required. If you have some imagination to understand logical connections, then you are quite capable of creating a project.

our recommendation

For more complex projects, a certain amount of experience is of course helpful. Have the basic project created by a qualified system integrator. In this way, you will later be able to easily change important parameters yourself if circumstances require it.


Roughly explained: Imagine the folder system on your Windows PC or iOS computer. Here you create your own structure, save files in it and create links to other folders. This is similar with the ETS software. The 'folders' can be floors or rooms and the 'files' in them are the sensors or actuators of the respective room or electrical distribution cabinet, which you then link to one another.

What types of installation are there for KNX blind actuators?

KNX blind actuators are available for every type of installation at eibabo®. For example, for installation in the electrical distribution, then these carry the suffix 'REG' for series installation devices or as a flush-mounted version 'UP' for installation in a mounting box or junction box or as a built-in version 'EB' for integration in ducts or similar. However, additional protection must also be taken into account for built-in versions depending on the installation.
