OPERATING TESTS AND ANOMALY DIAGNOSIS
The conditioner is able to perform a brief auto-diagnosis cycle to check that the internal components are operating normally and
during which it is possible to perform the configuration of the electronic control based on whether installation of the appliance was
performed to the upper part (to the ceiling) or lower part (to the ground) of the wall.
To activate the self-diagnosis function, proceed as follows:
-
power the appliance by connecting it to a socket or by acting on the master switch of the system;
-
ensure that the machine is on stand-by (no LED should be lit on the console);
-
Press the micro-key positioned underneath the hole to the left side of the console (fig. 19 ref. H) with a pointy object for at
least 10 seconds. The acoustic signal emitted indicates that the self-diagnosis function has been activated.
At this point the current configuration of the machine will be displayed for a few moments as indicated below:
LED A (red) on: appliance fitted with heat pump function;
LED B (green) on: installation to the lower part of the wall (to the ground) (factory installation);
LED C (orange) on: installation to the upper part of the wall (to the ceiling);
LED D (green) on: reset settings function after an active black-out (factory setting).
Then, all of the LEDs on the console will start flashing simultaneously for 10 seconds. During this phase, through the micro key
(fig. 19 ref. H), it is possible to modify the previously displayed setting related to the type of appliance installation.
NB: Configuration of the electronic control for installation to the upper part of the wall determines an automatic correction of the
room temperature detected of 3°C.
At this point the self-diagnostic function activates the appliance in heating mode (if fitted with the heat pump function) for approx.2
minutes and then in cooling mode for another 2 minutes.
It is possible to terminate the function prematurely simply by switching the appliance off using the remote control.
Should the conditioner block and signal an error (as indicated in the following table), specify the LEDs that are flashing to the service
centre in order to facilitate the intervention (fig. 19).

: flashing
WARNINGS SIGNALLED DURING NORMAL OPERATION SHOULD NOT BE INTERPRETED AS ANOMALIES.
LED A: indicates the filter may need cleaning
After this operation the LED must be switched off manually as indicated in section 2.6.1
LED B steady light: high battery temperature signal.
LED A + LED C flashing: continuous pump operation.
2.5.1
Evacuating condensate water during an emergency
If there should be a malfunction in the condensation water drain system, the air conditioner stops working and signals, with flashing
orange, green and red lights (the second and third LEDs from the left), the alarm status.
To enable the air conditioner to work temporarily until the service personnel arrive, you can drain the water out by following these
simple instructions:
-
remove the cap after having placed a good-sized container underneath it (at least 5-liter capacity) to collect
the water (see fig. 20)
-
after having cleared the fault, the service personnel will close the evacuation pipe.
