In brief: A ventilation control opens and closes window actuators via push button, radio or automatically in wind and rain. The VS-C24-7A controls up to 7 actuators at 24 V depending on current draw and is also suitable for blinds and roller shutters – for €60 net. A matching accessory is the remote control VS-C24-F-1 for €14 as well as Rain sensor and Ventilation switch from the accessories range. We ship stock items from Hamburg within 24 hours.
The factor of 57.3 resulting from the conversion of degrees to radians (180/π).

| Product | Task | Net price |
|---|---|---|
| VS-C24-7A controller | up to 7 actuators (depending on current draw), windows, blinds, roller shutters | 60 € |
| VS-C24-F-1 radio remote control | Hand transmitter 433.92 MHz with wall bracket | 14 € |
| VS-RS rain sensor | closes the windows when it rains | 33 € |
| VS-LT 230 ventilation button | Open/close push button for wall mounting | 11,99 € |
The control unit is the link between the operating element and the drive: It processes the signals from buttons and sensors and ensures that windows, flaps, and skylights open and close reliably. With the VS-C24-7A we offer a control unit for window actuators and roller shutters that operates chain, linear and spindle actuators for ventilation. Smoke and heat exhaust systems (RWA) require an approved smoke vent control panel, which we do not supply.
You decide how the system is operated: manually via a Ventilation switch, time-controlled or automatically via sensors such as the rain sensor VS-RS and the wind, rain, and light sensor VS-WRLS, so that windows close automatically in bad weather.
The choice depends on the number and power of the connected actuators, the operating voltage and the desired operating functions. We are happy to advise you on the right combination of control unit, actuators and accessories so that your ventilation system works smoothly from the start. All models are available from stock in Hamburg.

| Ventilation Button 230 V | VS-C24-7A control unit (24 V) | SHEV control panel | |
|---|---|---|---|
| actuators | one 230 V actuator per switch | up to 7 actuators with 24 V (depending on current draw) | 24 V actuators in the smoke vent system |
| Operation | Wall switch | Switch, radio (VS-C24-F-1) | Smoke vent buttons, smoke detectors, ventilation switches |
| Rain/wind | no | yes, with VS-RS or VS-WRLS | depending on the panel |
| smoke extraction | no | no – not a smoke vent control panel | Yes |
| At Vent Systems | VS-LT 230 from €11.99, VS-LT-A 12,99 € | VS-C24-7A 60 € | not in our range |
Rule of thumb: a single window without automation → 230 V actuator with switch. Several windows, radio or rain sensor → 24 V actuators with VS-C24-7A. How big the control unit must be is shown in the guide Calculating a 24 V power supply for window actuators.
Chain, linear and spindle actuators as well as roller shutters – for ventilation. Smoke vent systems require an approved smoke vent control panel.
Manually via a ventilation button, time-controlled or automatically via sensors such as the VS-RS rain sensor and the VS-WRLS wind, rain, and light sensor.
Yes, if a rain sensor or wind/rain/light sensor is connected to the control unit. It reports the weather to the control unit, which then closes the windows in time.
