13 WARNINGS and ALARMS
13.1 Dirty Filter warning:
Appears as soon as the internal fan has been powered for Tsf hours (in Stby mode, with intfan OFF, the dirty
filter hour counter hasn’t to be updated). When this occurs, the whole appliance must anyway continue to
work and the display unit (D1-D2) shows the relative warning code (‘Fi’,see the table below), except in stby
mode when no codes have to be displayed (‘- -‘). In case ‘Fi’ is displayed (unit ON), by pressing SW4, SW5
or SW6, the LCD shows for 5” on D1-D2 actual Tset or Timer value according to new selection, then
restores the ‘Fi’ code.
Both the warning signal and the function timer can be reset by
keeping the Stand-by (SW1) key pressed
uninterruptedly for at least 5 seconds (after 5 seconds it must reset even if the key is still pressed).
The warning signaling is restored after a power mains interruption. The function timer value (hour count) is
restored too after a power mains interruption (means the working hours counter has to be stored in
EEPROM when it changes value).
During dirty filter warning signaling all alarm conditions can occur. In this case the display unit have to
display the relevant alarm code (see the table below), Alarms never changes/resets the actual dirty filter
counter value.
13.2 Room sensor alarm:
As the room temperature values acquired exceed the range -10°C ÷ +70°C, the appliance stops to run (all
outputs are switched off), no more commands are managed (neither by remote controller nor by display unit)
and the relative alarm code (see table below) is shown on display unit LCD. Once the correct probe
operation is restored, the unit is placed in Standby mode.
13.3 Internal fan alarm:
When fan speed feedback acquired keeps lower than 400 rpm for 20 seconds in all the working situation
when the fan should operate, the appliance stops to run (all outputs are switched off), no more commands
are managed (neither by remote controller nor by display unit) and the relative alarm code (see table below)
is shown on display unit LCD. The board can be reset only by switching off the power supply.
13.4 Water level alarm:
If condensate water level switch keeps open continuously for more than 30 seconds the unit stops to run (all
outputs are switched off), no more commands are managed (neither by remote controller nor by display unit
switch) and the relative alarm code (see table below) is shown on display unit LCD. The board can be reset
only by switching off the power supply. When OF alarm has not yet occurred and max level switch closes or
the appliance is switched to stand by mode, the 30 seconds timer is reset.
13.5 EEprom data failure:
eeprom includes data about the air-conditioner working setting and no other sensitive information. It is
useful to restore the previous air-conditioner working mode when the power mains recovers after blackout.
If data stored in eeprom are loosen / invalid or read/write operations failed, the unit continues
running, the relative alarm code does not appear on the display unit and only the Autorestart
function is disabled (refer to 7.12.2 Autorestart paragraph).
