In brief: In a hotel, electric window actuators open fanlights in corridors, stairwells and the lobby and ventilate empty rooms on a schedule. A rain sensor closes everything before water gets in – even when no guest is in the room.
Typical uses in a hotel
- Lobby and conservatory: high fanlights and roof windows via a switch at reception.
- Corridors and stairwells: open fanlights centrally, for example in the morning by time programme.
- Rooms: ventilate after check-out, before housekeeping arrives.
- Restaurant and conference room: quick purge ventilation after events.
Which actuators are suitable?
For fanlights and bottom-hung windows the VS-KA with 250 N is usually enough. For roof windows and rooflights in the lobby there are stronger force ratings and Spindle actuators. Visually neater is the concealed VS-CKA 300.
steering
- VS-C24-7A ventilation control unit for up to 7 actuators with switch and sensor input.
- Rain sensor and Wind monitor for all windows that are left open unattended.
- Connection to the building management system via the i-series actuators, see Integrating window drives into building management systems.

Frequently asked questions
Does the actuator disturb guests?
Chain actuators run quietly and only for a few seconds. For rooms we recommend ventilating on a schedule only when they are empty.
What happens when it rains and the room is empty?
A rain sensor on the ventilation control unit closes the connected windows automatically.
Can the windows still be opened manually?
Yes, via the switch. How the window is operated without power depends on the hardware.
