▶ Press arrow key (/) until the lowest temperature is set.
▶ Test cooling mode for 5 minutes.
▶ Press the Mode button to set the heating mode (%).
▶ Press arrow key (.) until the highest temperature is set.
▶ Test heating mode for 5 minutes.
▶ Ensure freedom of movement of air baffle.
If the room temperature is less than 17 °C, the cooling mode must be
switched on manually. This manual operation is only envisaged for
testing and emergency situations.
▶ Otherwise, always use the remote control.
To switch on the cooling mode manually:
▶ Switch off the indoor unit.
▶ Open the upper cover of the indoor unit and lock in place.
▶ Press the Manual Control button ( Fig. 73) twice to start manual
cooling mode.
▶ Carry out the function check as usual.
▶ Press the Manual Control button again to switch off the indoor unit.

5 Troubleshooting
5.1 Faults with indication
WARNING
Risk to life from electric shock!
Touching live electrical parts can cause an electric shock.
▶ Before working on electrical parts, disconnect all phases of the
power supply (fuse/circuit breaker) and lock the isolator switch to
prevent unintentional reconnection.
If a fault occurs during operation, a fault code (e.g. EH 02) appears on
the display.
If a fault is present for more than 10 minutes:
▶ Briefly interrupt the power supply and switch the indoor unit back on.
If a fault persists:
▶ Call customer service and provide the fault code and details of the
appliance.
