Calibration Procedure www.vintageair.com On Vintage Air Gen IV and Gen 5 systems using cable converters or replacement electronic controls, it is necessary to calibrate the system to your specific control panel. This procedure ensures that the travel of your control panel levers or knobs is translated into precise control of the blower speed, temperature blend and mode door position.
Control Panel Calibration Procedure (Cont.) www.vintageair.com 1. Turn on the ignition switch (Do not start the engine). 2. Move the control levers/knobs to the positions shown. 3. Connect the white jumper wire to the gray program wire. Wait approximately 5 seconds for the blower speed to change if using a Gen IV system, if using a Gen 5 system wait for the blower to default to medium speed.
