I have a 14kW Mitsubishi Ecodan, which heats 2 zones (zone 1 = house with rads and zone 2 = kitchen with UFH) and DHW. I spent a good time playing with weather compensation only to find that room temperature with auto adaptation heats better with a higher COP - happy bunny! However, there does seem to be a slight issue. Auto adaptation seems to set itself to the lowest flow temperature to match heat input to heat output. So zone 1 heats well and is very efficient. But the system doesn't run zone 1 and zone 2 at the same time - zone 1 takes precedent if it calls for heat. So zone 1 seems to be on all the time (nice and snug!) and zone 2 seems to be off most/all of the time (a bit chilly). Does anyone have any suggestions as to how I might be able to get some heat to zone 2, while still being able to benefit from auto adaptation? Thanks in advance for any help or advice you can give.
