Hi tony my name is David and I'm an electrician. May I ask what is tripping? Is it the RCD or circuit breaker?
Breaker trips when Thermostat calls for off
Posted by Tony Benson, on
I cannot think of what may be a problem that takes out a trip when my heat pump switches off. It is not every time, but only happens when off is called for by the Thermostat. If I switch it off at the wall point, it is ok.
The system is old, around 2000.
At a service to look at the problem, there were lots of melted wire insulation. This was all cut back and the connections remade and all was well for a couple of weeks.
My thought is the Thermostat or the relay is faulty, but two service visits have not solved it yet.
