On units equipped with the Autoskim feature, a logic circuit in the controller automatically opens the solenoid valve for three seconds every minute. If the autofill feature is working properly, failure of the autoskim feature will be due to a malfunctioning controller and not the solenoid valve. (Proper operation of the autofill feature can be determined by draining water from the cookpot until the water level is below the shorter of the two
1.4.4 How the Water Heating System Works
To prevent lighting the burners when there is no water in the cookpot, these units are equipped with
a

The electronic ignition system controls firing of the burners. See Page
The temperature probe is used only when the unit is in the simmer mode. When the simmer mode is selected, logic circuits in the controller monitor the temperature of the water. When the water temperature drops below the simmer setpoint, the controller closes the heat relay, causing the burners to fire. When the water temperature reaches the setpoint, the controller opens the heat relay, extinguishing the burners. This process repeats as required to maintain the temperature at the setpoint programmed into the controller.
The controller is the interface between the operator and the other components of the equipment. In the water heating system, its function is to control the firing of the burners.
