I want to fit a cm 921 Honeywell RF timer with a stat I do not want the boiler working on the stat
Do I need to stay on line or will you e-mail me A.S.A.P
Still waiting for a reply for my last
This is an unsatisfactory answer i want to install a Honeywell wireless timer/stat
I already new i had to mount the receiver and give it power i needed to know what connections needed at boiler and to the receiver.
Like I said, use the room stat connections and link them through the receiver
You have asked how to connect this and I have told you.
Leave the heating on constant and wire the programmable room stat into the room stat circuit
This will turn the heating on and off when required and not affect the hot water production
I can send you a wiring diagram if you wish
