If the cooling system is set to “On” in menu 9.3.3 and the
outdoor temperature is greater or equivalent to the set start
temperature for cooling in menu 8.2.4, cooling starts.
Cooling stops when the outdoor temperature drops below the
set value minus the set value in menu 8.2.5.
The calculated supply water temperature is determined from the
selected cooling curve in menu 2.2.2 and the offset for cooling

Comfort setting hot water
The integrated water heater is a coil model and is heated by
circulating water, which is heated by the heat pump.
During “normal” consumption it is enough to run the heat
pump to supply the different tapping points of the house with
hot water. The temperature of the hot water in the water heater
then varies between the set values.
Under section 1.0 [N] Hot water temp. on page 23 there is a
complete description of menu settings for hot water
temperatures.
Prioritizing
When the water temperature in the tank drops, heat pump
operation shifts to hot water production. In case there is
demand for both hot water and heating/cooling for long time,
operation mode is periodically switched between hot water and
heating/cooling. For details, see menu 1.0 Hot water temp and
8.5.0 Period settings.
