Hi GasmanH
I was wondering could you please explain as if i was a five year old a volt free contact within a commercial boiler. I hear they are voltage free and not connected to the main wiring or the boiler if this is true how does it communicate with the boiler and what is its purpose?, and can it only 230 volts coming or only send 230 volts, and what would normally be used in this set up? Basically im clueless, any help much would be much appreciated.
