Is that still a thing? "Wassssup", I mean. Not bathroom extractors.
Anyway, my fellow bored apes, I need assistance with no clear picture as to what I have, only guess work.
New build 2020
Upstairs we have crap EnviroVent, asthmatic blowing out a candle through a straw style extractors.
These only come on with the lights (useless) and only if the 3 pole (I'm guessing) switch above the door is "on".
All over the house, we have "loop in switch" wiring. Therefore, without checking, I'm, expecting to find 4 cables going to the light switch.
1x LNE in (from previous light
1x LNE out (to next light)
1x TC or TCE for the light(s) - there are 4 spots in the bathroom
1x 3CE for the 3 pole isolator to provide a switched line to the extractor.
I might be wrong. Who knows.
What I want to do is:
A PIR / Occupancy Sensor and let this do the timing (ie, irrespective of the lights)
A new inline manrose extractor in the loft, in case I take a midnight dump (no overrun option)
Retain the 3P isolator, but might need to swap this for a 3amp FCU
So, can I repurpose the 3P isolator to effectively be the next "light" in the chain of loop in switch by running LNE into it, and out of it (to the next light). Only thing here would be that even "off" the isolator switch still carries a perm live.
Then, power the PIR / Occupancy sensor from the 3P isolator, which will handle switch line itself (ie, closes the circuit when it detects heat / movement).
Or, have I massively overcomplicated this, or massively misunderstood.
