Outside Air Temperature Indicator Calibration: Calibration
The outside air temperature indicator's displayed temperature can be recalibrated ± 5°F (or ± 3°C) to meet the client's expectations.
- Turn the ignition switch ON (II).
- Select the outside air temperature display and press and hold the SELECT/RESET button for 10 seconds. While you continue to hold the button, the display will scroll through temperature settings from +5°F to -5°F (or +3°C to -3°C) as shown.
- When the desired correction value appears on the display, release the button, and the recalibrated outside air temperature will be displayed. Each time a desired correction valve is entered, it replaces the previous valve.
Example:
Incorrect value = 68°F (20°C)
Desired correction valve = +2°F (+1°C)
Correct valve = 70°F (21°C)
Desired correction valve = -2°F (-1°C)
Correct valve = 66°F (19°C)
NOTE: To recalibrate the display to the true temperature, remove the outside air temperature sensor (A), but leave it connected. Submerge the sensor and a thermometer (B) in a container of ice water (C). Select the calibration mode as described above, then recalibrate the display to the true temperature.
