You need to connect electric windows, set up a ventilation control or replace existing drives? Here you will find everything important at a glance: which voltage, which controller, which sensors and where the data sheets are.
In brief: Our window drives are available in 24 V and 230 V. 24 V drives run on the VS-C24-7A controller, which supplies up to 7 drives and accepts rain and wind sensors. 230 V drives are switched with a ventilation push button or shutter actuator.
24 V or 230 V?
| 24 V | 230 V | |
|---|---|---|
| Control | Polarity reversal via controller | Separate open/close wires |
| Multiple drives | Simple on one controller | Via push buttons or actuators |
| Sensors | Directly on the VS-C24-7A | Via building automation |
Key points for the connection
- steering VS-C24-7A: 230 V input, 24 V output with max. 7 A, up to 7 drives depending on current draw.
- Cables: choose the cross-section according to length and current, see Laying cables for window drives.
- Power supply: total current of all drives plus reserve, see Calculate 24 V power supply.
- Sensors: VS-RS rain sensor or VS-WRLS-wind-rain-light sensor.
- Smart i series drives have a Modbus interface for building automation.
Datasheets and manuals
Data sheets and instructions are available on every product page in the downloads section. For planning several windows, use the Window actuator calculator.
Ordering and projects
Many drives and controllers are in stock in our Hamburg warehouse. For larger quantities or a whole building, we will prepare a quotation. Send us the window list, dimensions and photos via the Project enquiry.
Frequently asked questions
How many 24 V drives can be connected to a VS-C24-7A?
Up to 7, depending on current draw. Together the drives may draw a maximum of 7 A.
Is the VS-C24-7A a smoke control panel?
No. It is intended for everyday comfort ventilation. Smoke and heat exhaust requires an approved smoke control panel.
