Control Module of the ATC air conditioning
Automatic Temperature Control (ATC)
A.
Temperature control in the cab
•
Turn the temperature control dial (1) clockwise to increase the
temperature, or counter-clockwise to lower the temperature in the
cab.
B.
ATC Display (2)
The ATC display allows you to view the following information:
•
The desired cab temperature (1) in degrees Fahrenheit or Celsius. To
change between F. and C., see “Selection of temperature unit” on
page 33.
•
Symbol (2) is displayed when window de-fogging is in operation.
•
The mode of operation. Symbol 'A' (3) indicates that the system is in
automatic mode. In this mode, fan speed and heating/cooling are
controlled automatically to maintain the desired temperature.
When the letter 'A' is not displayed on the screen, the fan speed is controlled manually.
•
Symbol (4) is displayed when there is a fault in the operation of the ATC system. A diagnostic code linked to the fault
will be shown in the display.
•
The ATC operates in the temperature range between 60° F. (16 °C.) and 90° F. (30 °C.).
÷
Note: Symbol (3) is not displayed when the programmed temperature is minimum or maximum.
Fan Speed Control
You can increase or reduce the air flow by turning the fan speed dial (1).
•
Turn the fan speed dial (1) clockwise to increase the air flow from the
vents placed at the top of the cab.
•
Turn the fan speed dial (1) counter-clockwise to decrease the air
flow from the vents placed at the top of the cab.
÷
Note: If necessary, the automatic control of the air conditioning
(ATC) will vary the speed of the air flow to maintain the required temperature in the cab.
If you turn the fan speed dial (1) while the ATC mode is engaged, the ATC mode will disengage. The symbol 'A' disappears
and the fan speed is manually controlled by the fan speed dial (1).
To reengage the ATC mode, you need to toggle the ATC switch OFF and then back ON to reset the automatic mode. The
automatic temperature control works whether the symbol 'A' is displayed or not.
When the automatic air conditioning function or defogging is in operation, the ventilation increases to obtain a temperature
difference of 2 °F between the set temperature and that measured in the cab.
When the evaporator sensor reads a temperature below 80°F (26 °C) and the system requests heat, the fan speed does not
increase as long as the temperature of the sensor doesn’t increase.
