Main Power ON/OFF Switch (1) - Push the ON/OFF switch in order to power on the system. Push the switch again in order to power off the system.
Automatic Control Switch (2) - In order to enter the full "AUT" mode for automatic climate control, push this switch. However, if you push the switch again, you cannot turn off the air conditioning. When the system is in full "AUT" mode, you can manually change specific functions by pushing another switch. If you manually change a specific function, "AUT" does not appear in the display, but the unchanged functions will remain in "AUT" mode. Even on a day that is sunny, a climate control system with only a heater can cool the cab in full "AUT" mode if the ambient temperature is no more than 20 °C (68 °F). The climate control unit provides excellent operator comfort in the full "AUT" setting. Press the "AUT" switch for full "AUT" mode. Push temperature switch (3) in order to set the desired temperature. The temperature is only shown in metric values. All other functions of climate control will be handled automatically.In order to take advantage of the full "AUT" setting of the climate control system, always keep the sunlight sensor clean. Do not obstruct the sunlight sensor. If the climate control system is in the full "AUT" setting at engine start-up and the temperature inside the cab is too warm or too cool, the damper for fresh air ventilation may automatically close for a few minutes. This will help to bring the air temperature to the preset temperature more quickly.
Temperature Switch (3) - These switches control the temperature of the air that is coming from the air outlets in order to achieve the preset temperature. This preset temperature appears on LCD panel (4) . If the heating and air conditioning system is in the automatic mode, pushing these switches changes the preset temperature.
Increase - Push this switch in order to increase the temperature of the air that is coming out of the air outlets or push this switch in order to increase the preset temperature.
Decrease - Push this switch in order to decrease the temperature of the air that is coming out of the air outlets or push this switch in order to decrease the preset temperature.
Fan Switch (5) - The fan switch directly controls the fan speed. If the climate control system is operating in the automatic mode, pushing this switch overrides the automatically selected fan speed.
Increase - Push this switch in order to increase the fan speed.
Decrease - Push this switch in order to decrease the fan speed.
Compressor Switch (6) - Push the switch in order to turn on the compressor or push the switch in order to turn off the compressor. In humid conditions, the compressor may be used to remove moisture from the air in the cab. In cool weather, operate the compressor weekly in order to prevent leakage of the refrigerant gas. This will also help to
