Was at a property today, system boiler with programmer & thermostat for controls.
Customer is saying that CH is coming on automatically and house is roasting. He sais that turning down of the stat, and even turning the programmer CH to off is not turning the heating off. However, the stat and programmer both work properly when making a normal demand (bringing heating on) - iv checked the rest of the system just to make sure even of HW was on that its not somehow passing by the diverter valve - this obv was not the case all working OK.
Any ideas?
