2009-1-17 · Maybe its not 1&3 on the thermostat, or maybe its an electronic type that requires a neutral to work. Its not the boiler terminals that are volt free as if they were they would'nt do anything, it refers to the stat/remote timer having volt free contacts as some may have internally linked 230V relay contacts, and terminals '5&6' on the boiler may well operate at 12 volts.
