Heating season

The Heating season function means that the heat pump only produces
heating water when the outdoor temperature drops below a preset tempera-
ture. The preset temperature, Heating season limit, can be adjusted (factory
setting 18ºC, min = 10ºC, max = 35ºC), as can the delay before activation
(factory setting 4 hours, min = 0, max = 24 hours). The delay means that
the heat pump does not need to switch off and on as often when the outdoor
temperature is close to the limit value.
By increasing the value to above 35ºC the heat pump is set to continuous
heating season mode.
There is also an adjustable Direct start limit (factory setting 10ºC,
min = 5ºC, max = 17ºC) that means that the delay is ignored. Heating pro-
duction starts immediately when the temperature drops below the set value.
Heating, maximum operating time at hot
water requirement
This function is provided to satisfy hot water requirement during heat pro-
duction, when a hot water heater is fi tted. The factory setting is 20 minutes,
min = 0 and max = 60 minutes.
If base heat is required, e.g. in cellars,
it may be suitable to increase the
Heating season limit value.
