Comfort setting hot water
General
The integrated water heater is of 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’s compressor 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 49 there
is a complete description of menu settings for hot water
temperatures.

Prioritizing
If the water within the water heater requires heating, the
heat pump prioritises this and shifts to hot water mode
with the entire heat pump output.
In this mode, there is no heating or cooling.
Prioritizing can be affected via settings in the front panel.
See "1.0 [N] Hot water temp." on page 49.
Extra Hot Water
In all ”Extra hot water” functions, the temperature of the
hot water increases temporarily. The temperature is first
increased to an adjustable level by the compressor (menu
1.5) and then the electric additional heat increases until
the stop temperature is reached (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

NOTE
”Extra hot water” usually means that the electrical
addition has been activated and therefore increases
the electrical consumption.
”Extra hot water” can be activated in three different
ways:
1. Periodic time based extra hot water
■
Interval between increases is selected in menu 1.7.
Menu 1.8 shows when the next increase is due.
■
The increased temperature is maintained by the
electrical addition for one hour.
2. Schedule time based extra hot water
■
The start and stop times for the day of the week that
the increase is required are set in the sub menus for
menu 7.4.0.
■
The increased temperature is maintained by the
electrical addition for the selected period.
3.
Temporary extra hot water
■
The current ”extra hot water” mode is shown on the
display (A) when the button is pressed and by
pressing the button again the mode changes
between 3 hours and standby mode.
■
The increased temperature is maintained by the
electrical addition until the period of time has ex-
pired.
