Humidistat Fans

[ngoodson1969]

Hi,

Does a humidistat fan need a Switched Live, it seems that it doesn't need to go ON with the light but just whenever the sensor says so. In that case does it just need a Permy Live and Neutral?

Cheers
Nick

If the humidistat is built into the fan then you only need perm live, N & E.

Be carefull there is more than one type on the market. Some work fine as Sintra said. But others need a switched live to activate, then they time out and stop if the humidity levels are low enough. If not, they continue to run until the humidity as dropped, and then go off. These usually have adjustments for time and humidity settings.
