If the check detects an error, the error screen will be displayed (see section: Detection and Indication of Er-
rors).
It is possible to switch on the climatization system by pressing the (3) key, even though the engine is
stopped, providing the ignition switch is on. Since in this situation the battery is not charging, only the driver’s
heater and ventilation will operate with the minimum fan speed.
You can switch off the driver climate unit manually by holding down the (3) key for 2 seconds. It will be
indicated on the following screen.
Driver climate unit off screen.
1.2. Selecting the driver unit temperature.
To select the desired temperature for the driver unit, press the (2) or (1) keys.
If the passenger climatization unit is on, the selected temperature for the driver unit can be between +3º C
(5º F) and –3º C (5º F) of that selected for the passengers’ area. This means, if the selected passengers’ area
temperature is 22º C (72ºF), the driver can choose between 19º and 25º C (66º and 77ºF).
If the passenger climatization unit is off, the above limit does not apply and the driver can select any tem-
perature between 17º C (63º F) and 27º C (82º F).
The upper limit for the driver temperature is HI and in this position the heating will operate at maximum
power continuously. The lower limit is LO and in this case the air conditioning will operate at maximum power
continuously.
1.3. Selecting the driver unit’s fan speed.
To adjust the fan speed of the driver unit, press the (4) and (5) keys.
The driver unit fan speed can be selected between 5 levels. If you adjust the automatic speed setting se-
lected by the Ecomaster Comfort, the new speed selected will be displayed on the screen and the red LED
next to the (3) key will go off.
The selected speed can range from 1 to 5, with the following limitations:
If the engine is not running, only speed 1 is possible.
If the driver node is in A/C mode with the compressor on, the speed will never be lower than 3 to
prevent the evaporator freezing.
If the driver climate unit is off and the passenger climatization unit needs the compressor to switch
on, the driver’s fans will come on at speed 2 to prevent the evaporator freezing.
