settings" of the indoor unit installation or operation manual.

Detailed description

[6-02] Heater kit
Once installed, you can activate the heater kit by changing field
setting [6-02]=1.
From that moment on, the heat pump system will take the heater kit
into account whilst deciding operation. When the heater is actually
operating, the heater symbol ( is shown on the remote controller.
There is no step 1-2 indication.
[8-02] Emergency operation
During emergency mode, heating is only done by the heater kit, not
by the heat pump.
Activation of emergency mode is done by changing field setting
[8-02]=1.
Activating the emergency mode will stop the heat pump operation.
The pump of the indoor unit will be started, but heating itself is done
by the heater kit. If there are no error conditions in leaving or
returning water thermistors, the heater kit can start to follow
emergency operation.
NOTE
Before activating emergency operation, be sure to
activate the heater kit. The heater will stay in
emergency mode until the field setting is set back to
default [8-02]=0.
Benefit kWh rate power supply mode
NOTE
This concerns the benefit kWh rate power supply
mode of the RKHBRD indoor unit. For more details,
refer to the "Field settings" chapter of the indoor unit
installation manual.
If the benefit kWh rate power supply is used for the indoor unit, the
indoor unit will go into emergency operation automatically when the
power supply is interrupted.
