Roto E-Tec DAS

Extractor Fan Controller

In conjunction with the Roto E-Tec MTS contact element, the Roto E-Tec DAS extractor fan controller controls the proper use of an extractor fan.

With open flame, e.g. fireplaces or gas single-storey heating systems, the extractor fan in the kitchen may only be switched on when the windows are open. If they are closed, the DAS automatically interrupts the power supply, preventing a possible danger of suffocation from carbon monoxide.
