5 - Operation
Selecting ATC mode
Once you have activated the ATC mode, you can press switch (5) to switch
between the AUTO mode and the defog mode.
In defog mode, the air conditioning compressor operates full-time, and
the air is warmed up to promote the defogging of the windows. In this
mode, the display indicates symbol (2).
In AUTO mode, the system heats or cools the air to maintain the desired
temperature in the cab. In this mode, the display shows the symbol 'A' (3).
Window defogging
The window defogging mode uses the air conditioning to reduce the
moisture in the air for the purpose of drying the windows of the cab.
• Press switch (6) to activate the AUTO mode.
• Toggle switch (5) to display the defog symbol (2).
The temperature control dial can be adjusted to the desired value. If the
temperature of the air in the cabin is too cold, the temperature control
dial can be rotated in a clockwise direction to increase the temperature.
The temperature in the cab is controlled by a probe measuring the recycled air, while maintaining the temperature
requested by means of a heater valve. During the operation of defogging the windows, the a/c compressor is running
continuously, unless the evaporator probe detects that it is too cold, which may result in the formation of ice.
The computer of the ATC automatically regulates the speed of the fan to maintain the required temperature in the cab. It is
normal that the temperature of the air at startup is colder, caused by the engine being cold. If you reduce the fan speed,
during the heating of the engine, the computer of the ATC will disable the automatic mode of the fan speed. To re-engage
the automatic mode of the fan speed, the switch of the ATC (6) must be toggled off, then back on to reset the automatic
mode.
Operational problems
An error code is displayed if a malfunction is shown on the air conditioning system. For more information on the errors, see
