Wireless thermostat fitting

[moonstone911]

Hi,

New member here but have used the site for information before and cannot get over what a brilliant source of information it is.

Can anybody help with the wiring on a main 24he combi boiler. I am wanting to fit a Honeywell CMT 927 but cannot figure out the wiring connections in the boiler panel.

Any help would be great.
Many thanks,
Dave.

Remove the link between bk1 and bk2 and wire your switch live from the clock back to bk2. Then live neutral and earth in the boiler

Even though you havnt got an earth in the stat you should earth it at the boiler end to protect the cable

Don't forget your link between live and A in the clock
