Probably a rather elementary question but I am puzzled. Our thermostat (Honeywell electronic digital one, freestanding) is set at 15 degrees during the day, to save oil. However, I've found that some room radiators still come on, not boiling hot but warm, and they all have thermostatic valves set to between 1 and frost. When this happens the digital thermostat still shows '15'.
I thought the thermostast controlled the boiler going on or off. Do the rads override the thermostat if the room they're in is cold enough to trigger the rad to come on?
Grateful for advice! (BTW the boiler is a Worcester and only a year and a few months old and has been serviced. The boiler is in the garage.)
