Seen several posts on extractor fans but none that answer my specific query. I hope someone can help.
I want to fit an extractor fan in the bathroom of a period conversion flat.
Bathroom ceiling is old lath and plaster and there is no access from above (upstairs flat) so wiring into the lighting circuit would involve major work.
To get round this I thought about fitting a fan with either a humidity or PIR sensor and wiring it into the ring main.
I understand I would need to fit a FCU outside the bathroom to comply with regs but what would be the wiring arrangement from the FCU to the fan?
