System controls and display

There are three controls and an LCD window on the ClimaTrak (ATC) console.

1. Fan speed control (A) with AUTO switch (E)
2. Temperature selector knob (C) with economy mode switch (F)
3. Four-position air-flow control (D) with AUTO switch (G)
   • Defog/windshield
   • Defog/dashboard/footwell
   • Dashboard
   • Footwell

The desired temperature is displayed on the LCD display (B). To select alternating display of desired and ambient air temperature, change the settings in address ATC033. See Customization in Operation and Entering Diagnostic Addresses Using CommandCenter (Customer Level), Section "Diagnostic Trouble Codes and Customization".

When the system is in automatic fan mode, a fan symbol and the word AUTO are displayed. When the air-conditioning clutch is engaged (not in economy mode), the snowflake symbol is displayed. Direction of air-flow is displayed by an arrow pointing towards the feet or head, and the defog symbol appears. The word AUTO appears below the man when the system is in automatic air-flow mode.

In AUTO air-flow mode, selection is infinitely variable between defog, footwell and footwell/dashboard.

• Dashboard — Air is directed to the louvers in the dashboard.
• Footwell — Air is directed to the footwell, unless defogging is required.
• Defog — Air is directed to the windshield.
• Defog/dashboard/footwell — Variable settings to direct air-flow as needed.

NOTE: To ensure that the ClimaTrak system gives its best performance, clean the recirculation air filters in the cab regularly (see Service - As Required).
