need some advice on boiler stat measurement. getting into repair side of things som just wanna be sure. boiler stat if its simply gone ie not turning on at all its just no buzz, no ohms on multimeter? however say on a profile or puma how do you know if a boiler stat has lost calibration ie not heating enough or boier overheating. at least with thermistors you meassure resistance.!!! just wany to nail this basic question. thank you
