Andrew Smith : The easy way to do it would be leave the timer connected on 24hrs and wire the controller into the room stat circuit
JACUSTOMER-wcmwgffs- :

I want to fit a cm 921 Honeywell RF timer with a stat I do not want the boiler working on the stat

JACUSTOMER-wcmwgffs- :

Do I need to stay on line or will you e-mail me A.S.A.P

JACUSTOMER-wcmwgffs- :

Still waiting for a reply for my last

JACUSTOMER-wcmwgffs- :

This is an unsatisfactory answer i want to install a Honeywell wireless timer/stat

Andrew Smith : Sorry didn't realise you wanted RF until the reply
Andrew Smith : Again, you can link out the timer or leave it on continuous and link the programmable room stat into the room stat circuit
Andrew Smith : You will need to mount the receiver next to the boiler and give it power and take the two room stat connections through the receiver switch
JACUSTOMER-wcmwgffs- :

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.

Andrew Smith :

Like I said, use the room stat connections and link them through the receiver

JACUSTOMER-wcmwgffs- : Thanks for nothing will make sure I will not beuseing
JACUSTOMER-wcmwgffs- : Your site again
Andrew Smith :

You have asked how to connect this and I have told you.

Andrew Smith :

Leave the heating on constant and wire the programmable room stat into the room stat circuit

Andrew Smith :

This will turn the heating on and off when required and not affect the hot water production

Andrew Smith :

I can send you a wiring diagram if you wish
