temperature set point. The set point can be set manually (refer to
"Manual operation" on page
"Selecting weather dependent set point operation (only in heating
mode)" on page
6).
Startup (

At the start of a heating operation, the pump is not started until a
certain refrigerant heat exchanger temperature is reached. This
guarantees correct startup of the heat pump. During startup, icon
d
is displayed.
Defrost (

)
In space heating operation or domestic water heating operation,
freezing of the outdoor heat exchanger may occur due to low outdoor
temperature. If this risk occurs, the system goes into defrost
operation. It reverses the cycle and takes heat from the indoor
system to prevent freezing of the outdoor system. After a maximum
of 8 minutes of defrost operation, the system returns to space

NOTE
Powerful domestic water heating operation
In the case of urgent need of domestic hot water, the domestic hot
water temperature set point can be reached quickly by using the
booster heater. Powerful domestic water heating operation is forcing
the booster heater to operate until the domestic hot water
temperature set point is reached.
This function remains available in solar operation.
Quiet mode operation (
Quiet mode operation means that the unit works at reduced capacity
so that the noise produced by the unit drops. This implies that the
indoor heating and cooling capacity will also drop. Beware of this
when a certain level of heating is required indoors.
Two quiet modes are available.
