Well I have to say even after a beer that is a quality bit of photoshopping! The best I've seen on this forum ever! I would go as far to say I'd pay money for the .psd... 30mins... I think I see a flying sheep in the sky... Good way of doing the wiring though, especially with the double pole switch allowing manual control of the fan, however I would agree about losing the fan isolator as the fcu could do the same job if it were switched. It would then be easier to install, but it does tick all the boxes, manufacturers and regs etc. Good effort Elmer! :hurray:
