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 heat curve and weather comp are the first areas of the manual to read. Slow, small changes to avoid driving yourself crazy.
The other thing I needed to do was to set my radiators up properly, rather than my old gas boiler approach of "turn them on full and let the thermostat work it out"
