Abstract
A control system for a rethermalization appliance including one or more vats for containing water wherein the system enables designation of vat function and control of the water level in the vat(s). An input device enables the appliance operator to designate each vat function as desired. A timing and memory unit retrieves set point temperatures corresponding to the vat functions designated. Temperature controllers control the temperature of the water level in the vats based on the set point temperatures received from the timing and memory unit. Water level controllers receive input from sensors in the vats indicating low and full water levels. The water level controllers further receive input from associated temperature controllers indicating if the water temperature for that particular vat is within a predetermined range of the set point. Input to the water level controllers is also provided by the timing and memory unit to determine whether the associated vat is in an active finishing cycle. If a low water level is detected by a water level controller, water is automatically added to the vat when the water temperature in the vat is within the predetermined range of the set point and when the vat is not in an active finishing cycle.
