Figure 11: Graph that shows how the value for DEFR CURVE -16 can be set.
These three settings together create the defrosting curve and all three values have
an effect on when defrosting will start, even if it is mainly DEFR CURVE 0 and DEFR

Control panel

The heat pump has an integrated control system that is used to automatically
calculate the heat demand in the house where the heat pump is installed and to
ensure that the correct amount of heat is produced and emitted where necessary.
There are many different values (parameters) that must be referred to during the
calculation of the heat demand.
During installation and service, the control panel is used to set and change values
that have to be adapted according to the house demand. The control panel is inte-
grated into the front of the heat pump and consists of a display, a keypad and an
indicator. In the display, a simple menu system is used to navigate the desired set-
tings and values. During operation, the display always shows the set ROOM value,
the operating mode and the status of the heat pump.
The control system is controlled using a user-friendly menu system, which is shown
in the display. Use the keypad's four navigation symbols to navigate the menus and
increase or reduce the set values:
