Heating and cooling
(Heating and cooling summary)
Target temperatures for space heating and active cooling.
Upper limits for delivered power in the hourly simulation. Fixed climate profiles use matching defaults; with “custom” you set both limits yourself.
Default value in light gray in the field (insulation profile, NTA building category, desired indoor temperature). Empty input uses that value in the calculation; overrides are saved. Only with dynamic heat pump COP; affects the COP curve.
Compressor and boost behaviour (dynamic)
Same logic as air-water: thermal compressor cap; above it full resistive boost. Empty = unlimited. Legacy: kWel → kWel × heating SCOP on load.
Ground temperature ≤ required cooling supply temperature: circulation pump only, default 10 W electric per kW of cooling (COP ≈ 100). If the required temperature is lower than the ground, the compressor runs and the COP curve applies.
