A/c-Heater System - Automatic: Adjustments Saab 900 II

Calibration Mode

The A/C-heater control must be calibrated if the battery has been disconnected or discharged, a stepper motor replaced, or if the A/C-heater control panel has been replaced. The calibration and self-test are carried out by simultaneously pressing AUTO and OFF push button. The calibration and self-test takes less than 30 seconds.

All stored faults are cleared at the start and while calibration and self-test are in progress. The number of faults found will be shown on the A/C-heater control panel display.

CALIBRATION

If the battery has been disconnected or discharged, the A/C-heater control panel and stepper motors must be calibrated. Perform calibration by simultaneously pressing AUTO and OFF push buttons. (Схема №1)

The A/C-heater control panel display will flash once to confirm that it has been calibrated. During calibration, the display shows a zero (0) or the number of faults found (1-5). After calibration, the A/C-heater control panel display again shows the selected temperature. Calibration and self-test takes about 30 seconds.
