Activating and deactivating functions

Unit display
This function can be used to activate and deacti-
vate the display and the LEDs on the connected
indoor unit.

Quiet mode
In quiet mode, the compressor runs at a lower fre-
quency, and the indoor unit fan rotates at a slower
speed. This provides particularly quiet unit opera-
tion.
After 8 hours of unit operation, quiet mode is auto-
matically deactivated.
Quiet mode and the energy saving function cannot
be activated at the same time.

Energy saving function
If the energy saving function is activated in cooling
mode, the fan speed is set to automatic and the
temperature setpoint to 26 °C. In heating mode,
the fan also works in automatic mode, however the
setpoint does not change.
After 8 hours of unit operation, the energy saving
function is automatically deactivated.
The energy saving function and Quiet mode
cannot be activated at the same time.
5
Auxiliary heater (not fitted)
Switches on the electrical heating resistor in
heating mode (if fitted).
Service menu
The Service menu can be called up by pressing
the “Mode” and “Functions” keys simultaneously
for five seconds. Use the arrow keys to switch
between the parameters. With the “Enter” key a
desired parameter can be selected and adjusted
with the arrow keys. Once the desired setting has
been made, it can be saved by pressing the Enter
key. The “Back arrow” key is used to return to the
previous level or the home screen.
