Trying to get an extractor with a run-on timer to behave .... I can get it to work with a standard toggle switch borrowed from a bedside lamp, but as this is for a bathroom I have to use either a pull cord switch or a proximity switch. In the photo is my test set up, with the proximity switch connections (tested separately) to the right. If I replace that with the toggle switch it works, (although I have to "prime" it after switching mains power back on at the fused switch plate, by going on/off/on with the toggle first time round ... a bit like setting an outside light to work off the sensor/timer) Can anyone see, or get, where this is falling short? Does a proximity switch have "special needs"?! Thanking you kindly in advance
Your brave putting this up here, Ive the same problem, but i have been waiting over 10 years for my brother in law to come over from Australia to sort it out for me.
Explain the question! ... extractor with timer + regs required type of switch no workie .... Same unit + dodgy shocker switch workie fine.
ExACTly, but the bugger won't play ball if I use the proximity switch, which makes me think there be summat about them they proximity switches oi doz not know
Not sure what your trying to achieve here - the basic requirements for a run-on (timer) fan is for a permanent live to the timer terminal, a switched live from the bathroom/toilet light switch circuit, and a neutral connection. They can all be switched via a triple pole switch mounted outside the room at high level, then connected to the fan. Fair play for having a go, but for a bathroom installation you really need to get it fitted properly.....
£££! .... and these two units are very quiet, look the dog's (backlit) and now I've started I ... will ... finish ..... and I tried a separate PIR first off but no joy there either, which I put down to the fact that having TWO things with timers in them was beyond my abilities
The photo is just a demo/test rig set up after doing all of the above. The extractor doesn't have to be secondary to a light, in fact we didn't want it to be. I could put a light bulb in the set up but it wouldn't make any difference. The issue seems to be with the type of switch. PS ... The wiring for the unit puts the permanent live to the fan and the switched live (with or without light) to the timer
Hmmm, I',m tired been starting at screen too long today then chasing bad earths on the bus until the light went.. so i reserve the right to be well wrong, but is your proximity switch, latching or momentary? Edit and if its the latter, does it stay on for a long enough duration to trigger the fan?
