Currently have a 150 mm low voltage fan with a humidistat It seems to have stopped working if I turn on the power it starts up but closes down soon after Even when it's humid Anything I can check to get it working I have been advised to replace it with an inline fan Ideally I'd like it to come on only when humid And have facility to turn it off What's the best control options Fan extracts through a roof vent
I have not had much luck with a humidistat, the problem is until fan runs there is very little air circulation so damp air does not reach the sensor until very wet, so once it starts it drenched the sensor then it will not switch off. I will assume when you say low voltage you mean extra low voltage I.e. under 50 volt. It seems likely problem is with the power supply. But only way is to test, so what have you got to test with?
