- external control components (if any);
2. Check if the heat exchanger is connected correctly.
3. Make sure the CH and CW systems are switched on.
4. Switch the mains power on and/or plug in all connected
units.
If you switch on the mains power for the first time, the dis-

can also check this number via the service menu (see sec-

5. Only units that can cool:
- Test the operation of the condensate discharge pump:
Pour water into the external drip tray. The condensate
pump should start working shortly.

section 4.1).
7. Only units that can heat:
- Set the desired room temperature to a high value (see

- Feel if the discharged air gets warm. This may take
some time. You may want to read the actual discharge
temperature from the service menu (section 8.2) – only
