Re: Humidistat to control existing fan, £cheap?

Any tips where to get a stand-alone humidistat to operate an existing fan

Waste of time, been there done that. I added a humidistat in bathroom onto existing fan. In spring/summer/autumn worked fine, have shower fan runs, fan eventually turns off. However in winter when the bathroom temperature is lower the fan just comes on all the time. Change setting then fan doesn't work rest of year.

Sorted by buying an expensive (over £100 I think) VentAxia fan that has a temperature compensated humidistat and that worked wonderfully as expected all year round. Also had a timed override, which I connected to a chorded momentary action pull switch, so that if someone dropped a non humid smelly in the bathroom the fan could chew it away !!!!!

I'm not sure the wet ones would trigger the humidistat either unless it was in your pants. You could mount the fan in your pants too and it really would chew it away. (Might make a bit of a mess on the wall though.)

Why do I get evil thoughts of rewiring the emergency cord pull in disabled toilets to either turn off the light or flush the toilet.
