I am baffled by our heat pump, and why it is heating even though it is not a time that it should be heating, and that it is already hotter than the temperature to which it should be heating.
Tomorrow, I need to read some manuals, and work out what is going on.
@neil There's a solenoid that switches from heat to cool mode. After a thunderstorm, ours got stuck in "cool" mode. We didn't notice until winter when we wanted not-cool.
