6.2 Functional test of device
The system can be tested once the installation including tightness test
has been carried out and the electrical connection has been established:
▶ Connect the power supply.
▶ Switch on the indoor unit with the wired room controller.
▶ Switch on cooling mode and set the lowest temperature.
▶ Test cooling mode for 5 minutes.
▶ Switch on heating mode and set the highest temperature.
▶ Test heating mode for 5 minutes.
▶ Ensure the function of the display unit and the wired room controller.
Observe the operating instructions provided for operation of the indoor
units.
If the room temperature is less than 16 °C, the cooling mode must be
switched on manually. This manual operation is only envisaged for
testing and emergency situations.
▶ Normally always use the wired room controller.
Activate manual operation:
▶ Press the key for manual operation ( Fig. 28, [1]) one to three
times to step through the following operating modes:
– Automatic mode
– Manual cooling mode
– Off
6.3 Handover to the user
▶ When the system has been set up, hand over the installation manual
to the customer.
▶ Explain to the customer how to use the system, referring to the
operation manual.
▶ Advise the customer to carefully read the operation manual.
If a fault occurs during operation, a fault code appears in the display
(e.g. EH 02).
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.
