RF-VM

Radio Ventilation Module

With the RF-VM fan module ventilation devices from other manufacturers can be driven by the WS1, WS1000 (Colour or Style models) and KNX WS1000 Style controllers.
With the Remo 8 remote control or via the wireless switch interface, RF-B2 devices connected to the RF-VM can be switched directly.

Note: No ventilation module is required for Elsner Elektronik wireless controlled ventilation units.
