Honeywell Programmer wiring diagram

[Alan]

Hello group,

Can anyone point me to a wiring diagram on-line for the Honeywell ST699 CH programmer? A colleague has one which is not switching the heating at the moment (but hot water is OK) and I want to see if I can wire the heating circuit onto the HW relay to get him going until the replacement arrives.

Thanks in advance,

Alan.

You can download a user guide from

I can't see an installation guide on the Honeywell site. I suggest you contact them and ask for one.

If it just uses the CH On output, then wire the CH side to permanent live. Control the system with the room thermostat until the new programmer arrives. Besides a couple of nights with the heating on isn't going to kill the gas bill. Better still, replace the room thermostat with a programmable type anyway.
