68-0063—3 10 L8104A,B,C,D SETTING AND CHECKOUT Setting and Check out SET CONTROL TEMPERATURE If the potentiometer is mounted on the control module, turn the selector knob to the desired temperature. If the potentiometer is remotely mounted, the position of the flat part of the shaft determines the approximate control temperature.
11 68-0063—3 L8104A,B,C,D SETTING AND CHECKOUT • OPERATION TABLE 2—THERMISTOR RESISTANCE AT VARIOUS TEMPERATURES IN CELSIUS. Operation L8104A,D When the temperature at the sensing bulb drops below the setting on the potentiometer, the relay contacts in the electronic control module make to open the gas control or turn on the ignition module.
