After-heating element
You will only have this menu item if an electrical after-heating element or a water after-heating element has been installed, and if it
has been activated in “Service settings”.
If you want to be able to control the supply air temperature, you will need to install an after-heating element. This allows you to control
the supply air temperature irrespective of the outdoor temperature. The after-heating element can also contribute towards the heat-
ing of the dwelling.

Cooling
The unit can cool the dwelling via bypass-cooling and/or active cooling via the heat pump. For the unit to switch to cooling mode it must
operate in summer mode, or you must activate cooling in “Operating function”.
Bypass cooling:
If the room temperature, measured in the extract air, is higher than the cooling setpoint -2 ºC and the outdoor temperature is below
the room temperature, the bypass will open and commence bypass cooling.
The bypass will close again once the room temperature reaches the desired level +1 ºC
If the outdoor temperature exceeds the room temperature and cooling becomes necessary, the bypass will not open. However, the
unit will start cooling recovery via the heat exchanger where the outdoor air is cooled by the extract air.
Active cooling:
If the room temperature (measured in the extract air) is higher than the desired room temperature + the cooling setpoint, the compres-
sor will start up and begin active cooling of the supply air. The compressor will stop when the room temperature falls below the cooling
setpoint -1ºC.
> Cooling
*When domestic hot water is needed, the heat pump prioritises producing domestic hot water and does not run cooling. However, it
opens the bypass damper if cooling is required.
If cooling is to have a higher priority than hot water, the unit will cool the supply air and store the heat in the hot water tank during that
period. The domestic hot water will be heated, but not as quickly as usual in hot water production.
ATTENTION
An after-heating element is not included as standard. However, you can order it as an additional extra, and it can also be
retrofitted.
> Turn on/turn off Settings:
Standard setting:
Description:
Off / On

The user can turn the after-heating element on and off here.
> Cooling setpoint Settings:
Standard setting:
Description:
Off / +1 / +2 / +3 / +4 / +5 / +7 / +10 ºC
Off
Off: Active cooling is deactivated.
Set point + X ºC: Indicates when active cooling is to start. The
set point for desired room temperature is selected on the front
of the panel.
> Ventilation in cooling mode Settings:
Standard setting:
Description:
Off / 2 / 3 / 4
Off
Off: The fan speed level does not change when the unit switches
to cooling mode.
Level 2-4: Select the fan speed level you want the unit to switch
to when in cooling mode. This happens already at bypass cool-
ing.
> Priority Settings:
Standard setting:
Description:
Water / Supply air
Water
This indicates whether the cooling function is to have a higher
priority than production of domestic hot water*.
