I am having problems with the central heating stopping. It seems the communication between the HCW80 stat and the HC60NG is dropping out - the boiler stops but the room temperature has not reached the stat setting point and the green light on the HC60NG has not come on. It should be calling for heat. If I turn the stat down to its lowest setting then up to a high setting and back to its normal setting all is OK again - the green light comes on, the boiler strikes up again and all is well for an hour or so. Then it all happens again. I have changed the batteries in the HCW80 and reset the binding but to no avail. Do I need a new stat? Any advice welcome.
