Weather compensation automatically adjusts the flow temperature according to the outside temperature.
When it is colder outside
The heat pump gradually increases the flow temperature to meet the increased thermal load.
When the weather is mild
The water temperature decreases, which usually improves the COP.
Why it suits underfloor heating
Underfloor heating has high thermal inertia and works best with stable, mild settings rather than frequent on-off cycling.
Compensation curve
Proper adjustment is done gradually to ensure comfort without an excessively high flow temperature.
