EHS electric combi primus 14000
I have an EHS primus 14000 electric combi boiler and have bought a tado wireless thermostat. I can’t find find help anywhere on how to wire this. There is a cable which hangs outside the boiler to connect to a thermostat. I’ve been told that this is 0 volt and not to power the thermostat only to send info to the boiler. Any help appreciated.
