It never got resolved. 3 different engineers came and none of them were able to fix it. They ended up saying this is just the way it is and that if you want an accurate one you need a wired therm.
there is a black wire coming out of B but it is going to the danfoss programmer. There is no wire coming out of the receiver going directly into the boiler. :(
Hello All,
I am having problems with HCW80 room stat. It is not regulating the temperature but only acting as an on/off switch for the boiler.
Warmfront (govt scheme) installed a new baxi duotec boiler with a danfoss programmer and the honeywell wireless thermostat just one month ago...
