Diagnostic Parameters & Displays

While in the diagnostic mode, it is possible to check several different system parameters (circuits or systems). This is done by pressing "FAN (arrow up)" or "FAN (arrow down)" touch switch until the desired index number is displayed. Once the desired index number is displayed, press the "°F/°C" touch switch to display the parameter value.

Additional parameter index numbers can be displayed by pressing the "FAN (arrow up)" or "FAN (arrow down)" switch until the next desired number is displayed. The value for the index number can be displayed by pressing the "°F/°C" switch. This process can be continued as often as required while in the diagnostic mode.

SYSTEM PARAMETERS

02 Inside Air Temperature Sensor - Value should Increase as Temperature Decreases.

03 Outside Air Temperature Sensor - Value should Increase as Temperature Decreases.

04 Sun Load Sensor - Above 200 = Dark; 150 or below = Bright Sun.

05 Engine Temperature - Degrees Celsius (°C).

06 Vehicle Speed - Miles Per Hour.

11 Temperature Air Valve Position Command - 0 = Full Cold Position; 225 = Full Hot Position.

12 Temperature Air Valve Position Feedback - Initial Reading During Calibration should be 180 or Higher.

13 Temperature Air Valve Position - Full Hot - Initial Reading During Calibration should be 180 or Higher.

14 Temperature Air Valve Position - Full Cold - Initial Reading During Calibration should be 50 or Lower.

18 Number of Consecutive short Compressor - If 10 Short Compressor Cycles (for Low Freon Detection) Compressor will be Disabled.
