- Check after a few seconds to see whether the
equipment heats normally (if equipped with heat pump
function) for about 2 minutes and then, after a few
seconds, that it cools for another 2 minutes.
Before concluding the self-test, the electronic part tests
the temperature probes to make sure they are operating
normally. If any of these should not be working, the
corresponding signal led remains lit for 20 sec. (see
table on next page).
Should there be a jam in the air-conditioning system with
alarm signals according to the table here following, please
be ready to refer to the Service Centre which leds are
blinking in order to simplify their intervention.

The end of the self-test will be signalled by all the leds
lighting up at once and blinking ten times, as well as by
an acoustic signal.
At this time, you can adjust the temperature reading on
the room temperature sensor. This correction is important
if the air conditioner is installed high on the wall in a room
where the warm air tends to stratify upward (as in rooms
with high ceilings or other sources of heat besides the air
conditioner). The sensor will read a temperature 3°C lower
than the effective one, in this case, to compensate for
the difference between the lower inhabited part of the
room and the temperature at the height of the sensor.
To enter or remove this correction proceed as follows:
1 Check the status of the machine as described
previously, and if no correction has been made, press
the button on the console while the acoustic signal is
on at the end of the self-test.
2 To remove the correction, press the button while the
acoustic signal is on at the end of the self-test.
