TIMER adjustment
When the system is switched off, it is possible to vary the operating time envisaged by the timer in STANDARD
mode between a minimum of 1 and a maximum of 99 hours.
Press the VENT + and TEMP – buttons at the same, the display shows the default value (6 h) and the clock and
half snowflake symbols will light up (see fig.3).
Quickly pressing the VENT + or VENT – button increases or reduces the value by 1 hour each time the button is
pressed.
Pressing the same buttons for longer increases or reduces the value in steps of 10 hours.
Also with the system switched off it is possible to change the operating hours envisaged by the timer in MAX AC
mode in the same way.
Press the VENT – and TEMP + buttons at the same, the display to show the default value (4 h) and the clock and
full snowflake symbols will light up (see fig.4).
Quickly pressing the VENT + or VENT – button increases or reduces the value by 1 hour each time the button is
pressed.
Pressing the same buttons for longer increases or reduces the value in steps of 10 hours.
PROGRAMMED START FUNCTION
When the system is switched off, it is possible to set the programmed start of the system between 1 and 99 hours.
Quickly press the MAX AC button, changes the value by 1 hour at a time and the clock symbol will light up (see
fig.5).
Pressing the same button for more than 2 seconds changes the value in steps of 10 hours and the clock symbol
will light up, remaining lit until the system starts.
If you wish to deactivate the function, press the MAX AC button until a value of 0 is reached, or switch on the
system.
VENTILATION (FAN)
If the fan increase or reduction buttons (VENT + or VENT –) are pressed when the system is switched off, only the
evaporator fan is activated, with the choice of 6 different speeds, shown on the central control unit display.
To switch off the fan it is necessary to set the value 0 on the central control unit display, using the fan speed
reduction button (VENT –).
SAVE BATTERY FUNCTION (AC / FAN)
The save-battery function starts when the power falls below a value of: 21,5V (24V version) / 10,4V (12V
version).
In this case, the system (AC or VENT) shuts down, also deactivating the fan function and the message E1
appears on the display and the battery symbol lights up.
When the power returns, for at least 10 seconds, to the value of 25V (24V version) / 11,7V (12V version), the
system is automatically reactivated, starting up the condenser fan, followed by the evaporator fan and compressor.
