[QUOTE="kerching, post: 520124, member: 11861"] Bearing in mind I know nothingI don't think you will have two supplies going to PCB, more like supply in, control,and pump out what are you testing this 180V with? if it's new isn't it better to get the installer back to,save voiding warranties etc? bearing in mind I know little about these things BUT the installation manual only shows one supply ( pages 10/11 ) so my money's is on it being an electronic switch in the programmer ( as opposed to mechanical ) and there is a back feed /leakage big enough to trip an RCD/RCBO is this your own boiler or a customers?.....just asking [/QUOTE]
