Had a small extension built which has a bathroom in it. I had requested that the extractor had a humidistat installed to ensure it would run until the room was clear from the shower. I was told this was done.
I have just opened up the fan case to see how to adjust the humidistat settings as it isn't doing g a great job. From what I can see the fan doesn't have a humidistat, just a timer, which would explain why it always runs for the same amount of time. I'm annoyed at this but the way things have gone with the build I don't think I'm going to get anywhere with the electrician.
So, considering the cost of a reasonable humidistat and timer controlled fan, I was going to replace it myself. However I need to understand the wiring.
The fan has its own isolator and is triggered when the light switch is turned on. The cable is 3 core plus an earth.
Before I buy anything, what I wanted was for the fan to come on when the light is turned on, or when humidity reaches a certain level. Is this possible? If not is it easy/correct to bypass the light switch so that the fan is controlled only by the humidistat?
Hope that makes sense
Thanks.
