I had an extractor fan installed by an electrician when he did some other work in the house. It was an Awenta brand (not my choice but was included in the price of the other work) with timer and humidistat. I never liked the Awenta fan so I decided to replace it with an Xpelair one with just a timer.
The Awenta was wired into the light switch outside the bathroom so would come on with the bathroom light. The wiring to the Awenta fan was Brown to Live, Grey to Neutral, Black to Timer and Earth sleeved and running inside the casing.
I've disconnected those and wired them onto the Xpelair as Brown to Live, Grey to Neutral, Black to LS and Earth sleeved and running inside the casing. There is a dial inside the fan for the timer to adjust from 2 minutes to 32 minutes. I set that at just after 2.
With the bathroom light switch off, I turn the fuse on from the CU. The fan doesn't come on. I turn the bathroom light on and the fan starts up. I turn the bathroom light off and the fan continues as expected as it has a timer but it doesn't stop after 2 minutes. It doesn't stop after 5 minutes. It doesn't stop after 8 hours. It's still spinning away.
If I knock the fuse off in the CU, the fan stops. I turn the fuse on and the fan doesn't start back up until I turn the bathroom light on again, then it starts and won't turn off until I kill the power in the CU again.
I've tried to change the grey and black the other way around. That way the fan goes on when the bathroom light is turns on but goes off as soon as you turn the light switch off. It won't even run on the timer.
It's the Xpelair XS100T fan.
Any help would be much appreciated.
