Like DorrisMancer, my thermostats were all wired with three core + earth mains cable (6243Y 1.5mm2 cores; red, yellow, blue; later brown, grey, black). That cable is rated to 19 Amps (in conduit) - that's 4kW at mains voltage - far more than would ever be needed for a boiler and pump.

No way am I going to try to drill out a full depth back box when I don't have to.Last edited by DBMandrake; 18 September 2019, 09:15 PM.

After butchering (don’t ask) the power supply, supplied with the ATF800, I bought a replacement 5V 1A power supply off of eBay and cut the end off before connecting the now exposed red wire to + and the black wire to - on the ATF600 which has worked a treat - the power supply is plugged into a mains socket on the wall behind that of the wall mount after I drilled a hole for the cable to feed through. ATF600 wall mount with ATF800 power supply and no 4v transformer in sight. NB. + on the ‘white’ power supply out the box of the ATF800 in my case was in fact the wire with the writing on not that with stripes which I overlooked hence the initial error.
