Hot water Supply is unlimited in case 8
ℓ
/min at the condition as
the capacity is bigger than hot water supply.
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
Menu 8.5.0 Period settings.
Extra Hot Water
In all “Extra hot water” functions, the temperature of the hot
water increases temporarily. The temperature is rst increased
to an adjustable level by the compressor (Menu 1.5) and then
the electric heater is energized until the water temperature
reaches the stop temperature (Menu 1.4).
Temporary “Extra hot water” is activated manually, whilst time
based extra hot water is activated using the settings made in the
control computer.
When:
■ “A” appears above the
icon, temporary extra hot water
is active.
■ “B” appears above the
icon, time based extra hot water
is active.
NOTE
“ Extra hot water” usually means that the electric heater
is activated regardless of Allow add heat setting (menu
8.2.1) and therefore increases the electrical
consumption.

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 93 there is a
complete description of menu settings for hot water
temperatures.
