Seasonal stop
Seasonal stop
is at which outdoor temperature the heat pump will be blocked, or allowed, to produce heat.
The time it takes for the heat pump to switch from, or to, the heat season mode when it reaches the seasonal
stop value is determined by a calculation in the heat pump control system. E.g. the bigger heat increase of the
outdoor temperature over time, the faster the heat pump will decide to stop producing heat on the supply line.
The seasonal stop is set to 17 °C by default.
Supply line min and max
The MIN and MAX values are the lowest, respectively highest set point values that are allowed for the supply
temperature.
Supply line min
is the minimum permitted supply temperature, if the temperature for seasonal stop has been
reached and the heat pump has stopped.
Adjusting the minimum and maximum supply temperatures is particularly important if your home has under-
floor heating.
If your house has underfloor heating and parquet floors, the supply line temperature must not exceed 45°C.
Otherwise the floor might get damaged. If you have under floor heating and stone tiles, the MIN value should
be 22-25°C, even in summer when no heating is required. This is to achieve a comfortable floor temperature.
If your house has a basement, the MIN value should be adjusted to a suitable temperature for the basement in
summer. A condition for maintaining the heat in the basement in the summer is that all radiators have thermo-
stat valves that switch off the heat in the rest of the house. It is extremely important that the heating system
and the radiator valves are tuned correctly. Also remember that the value for seasonal stop needs adjusting
upwards for summer heating.
