Programmer Temperature Adjust

1. Set temperature control for 75°F and "Auto." Measure actual temperature in vehicle using suitable thermometer.
2. Connect suitable volt meter to test lead of programmer pin "W" and to ground. Record programmer voltage at this point.
3. Temperature changes at specific control settings are made by changing programmer voltage for that setting. To change programmer voltage, adjustments are made using a small blade type screw driver to reset the temperature adjustment potentiometer. Increasing temperature requires raising programmer voltage .2 volts per degree. For example, if passenger compartment is 4°F colder than control setting, programmer voltage must be raised .8 volts to correct difference between indicated control temperature and actual temperature. Decreasing temperature is accomplished by lowering programmer voltage .2 volts for each degree lower required.
4. Disconnect voltmeter and check passenger compartment temperature comfort level.
