In this mode you can select a delayed start. This can
be useful if you have just had a shower, for example,
in order to allow the ventilation unit to remove the
moisture.
4.7.3. High
Used if there is a temporary increased need for
ventilation,
for example if you take a shower or have visitors so
there are more people than usual.
As standard, this mode is set as a temporary mode,
i.e. you can set a duration. When this time has elapsed,
the ventilation returns to the previous mode. You can

Change water mode
4.8.1. Eco
The most economical way to produce hot water.
The tank’s top sensor is used to trigger the tank to be
charged with hot water from the heat pump.
Charging is triggered when there is about 15% hot water
remaining in the tank.
4.8.2. Comfort
An economical way to produce hot water.
The tank’s middle sensor is used to trigger the tank to be
charged with hot water from the heat pump.
Charging is triggered when there is about 50% hot water
remaining in the tank. If hot water consumption is high
and the hot water level in the tank falls below 15%,
additional electric heating is activated to increase hot
water production.
4.8.3. Boost
A temporary mode with adjustable duration, which can
be used when extremely high hot water consumption is
required.
Hot water charging starts when the hot water level falls
below 100%, and additional electric heating is activated
if the level falls below 50%. When the time set for boost
has elapsed, the water mode returns to the previous
mode, Eco or Comfort.

Inside the

module
The combination of a very low outdoor temperature and damp outlet air can lead to ice
formation. This is not usually a problem; as soon as the operational conditions return to
normal, the ice crystals are converted into steam and removed with the exhaust air. If
extremely cold temperatures persist for a long period, the unit should be checked for ice.
