Relay (K1)

Controlled by hold thermostat. Enables timer circuit.

Relay (K2), LLCO

Low Level Cut-Off (LLCO) external relay. Only energized during

 

drain. Controls Flush, Fast Fill and Vacuum Relief solenoids.

Relay (K3), Drain Relay . . . . . . . . . . . . . . . . . . Controlled by Time Delay Relay. Only energized during drain cycle. Controls WLC board and LLCO relay K2 during drain. Disables heating and timer circuitry.

Relay (K4) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . (Professional models only) Latches Ready light on. Allows power to superheater.

Relay, Time Delay

Controlled by the power switch. Output becomes active for 90

 

seconds when power switch is turned to off. Only used during

 

drain cycle.

Solenoid (1SOL), Cooling . . . . . . . . . . . . . . . . Controlled by the condensate thermostat. Mixes cold water with hot condensate water from cooking chamber to reduce water temperature at drain.

Solenoid (2SOL), Flush . . . . . . . . . . . . . . . . . . On only during drain cycle. Mixes cold water with tank water before entering drain box. Keeps drain hose clear of debris.

Solenoid (3SOL), Fast Fill . . . . . . . . . . . . . . . . Initial tank fill for Professional machines. Used during last stage of drain cycle to flush drain opening free of debris.
