For all models
1. Check the following connections:
- power supply;
- control cables between control panel and unit (or
units);
- external control components (if used).
2. Switch the power supply on and/or plug in all connected
units.
If you switch on the power supply for the first time, the
display will briefly show the number of connected units (in
opposite example, 2).
3. Press the key in the control panel twice.
If the unit works correctly, the display will show informa-
tion, as in opposite example, or the LED will be lit:
If the control panel does not work, or if the display reads
and/or an fault code (E or F plus a number), refer
to section 6 'Faults'.
4. Switch the air curtain on using the control panel (see sec-
tion 3.1).
For water-heated models
Check if the heat exchanger is connected correctly:
1. Make sure the central heating system is turned on.
2. Make sure heating is enabled in the control panel (see sec-
tion 3.3).
3. Feel if the discharged air stream gets warm. This may take
some time.
4. Vent the heat exchanger, if necessary.
For electrically heated models
5. Make sure heating is enabled in the control panel (see sec-
tion 3.3).
6. Feel if the discharged air stream gets warm.
