Question:
Is this suitable for 24v motorised vėlus windows?
Answer:
YES, if:
Your windows are controlled via a VELUX KFX 210 (or similar) smoke‑vent control unit, which operates on 24V DC.
The KFK 200 switch is designed specifically for VELUX smoke ventilation systems and:
Works on 24V DC
Connects directly to the KFX 210 control unit to open/stop/close the window motors
[lbroofwindows.co.uk]
NO, if:
You have standard electric VELUX INTEGRA® windows (230V / solar).
The KFK 200 is not a normal window switch — it is part of the smoke ventilation system, not compatible with typical domestic electric roof windows.
To control standard electric/solar VELUX windows, you would normally use:
KLI or KLR controllers
VELUX Touch
KLF 200 interface module
Question:
Good morning, please could you let me know if this item will operate a standard roof light window that has a chain operated opener/closer. I have damaged the xisting unit and cant seem to fine a replacement for it. The unit I have is the following SOMFY 1N1S-DC ROLLER BLIND/ROLLO - REF NUMBER 1870069
Answer:
I'm sorry for any confusion, but the VELUX KFK 200 Wall Switch for Comfort Ventilation is specifically designed to be used with the VELUX smoke vent system. It's not intended to operate a standard roof light window or a Somfy roller blind system. It seems like you may be looking for a different product. I would recommend using our website search function to look for the specific Somfy product you mentioned, or you could contact our customer service team for further assistance. They may be able to help you find a suitable replacement for your damaged unit. If you're interested in exploring other products in our range, we also have a variety of flat roof windows and accessories available.
