A control system for a refrigeration system having a refrigeration compartment and a quick chill/thaw pan. A main controller board, electrically connected to a temperature adjustment board and a dispenser board through the serial communications bus, controls the temperature of the refrigeration compartment and the quick chill/thaw pan. The control system accepts a plurality of inputs to determine a refrigeration mode and to execute a plurality of software algorithms to control the refrigeration compartment as both a chill pan to rapidly chill food and beverage items without freezing and a thaw pan to timely thaw frozen items at controlled temperature levels.

What is claimed is: 1. A control system for a refrigeration system, the refrigeration system including at least one refrigeration compartment, a quick chill/thaw pan located in the refrigeration compartment, an air handler including a heater element, a damper, a fan for supplying air to the quick c
What is claimed is: 1. A control system for a refrigeration system, the refrigeration system including at least one refrigeration compartment, a quick chill/thaw pan located in the refrigeration compartment, an air handler including a heater element, a damper, a fan for supplying air to the quick chill/thaw pan, and a temperature sensor for detecting a temperature of the air handler, said control system comprising: an electronic controller comprising a main board, a temperature adjustment board, a dispenser board, and a serial communications bus, said main board electrically connected to said temperature adjustment board and said dispenser board through said serial communications bus for controlling the temperature of the refrigeration compartment and the quick chill/thaw pan; and a human machine interface (HMI) board comprising a plurality of input selection keys, said controller electrically connected to said HMI board and configured for user selection of a quick chill mode, a quick thaw mode, and a temperature zone mode, wherein user selection of said temperature zone mode includes user selection of one of a temperature and a temperature range to be maintained within the quick chill/thaw pan, said controller configured to control an operating speed of the fan based on a detected temperature of the air handler, said controller further configured to energize the heater element in order to maintain a temperature in the quick chill/thaw pan and open the damper to circulate air between the air handler and the quick chill/thaw pan when the heater element is energized. 2. A control system in accordance with claim 1 wherein said input selector keys comprising at least one of a quick chill key and a quick thaw key. 3. A control system in accordance with claim 1, said electronic controller configured to: accept a plurality of inputs including at least a refrigeration compartment temperature and an input indicating operation of one of said quick chill mode, said quick thaw mode, and said temperature zone mode; determine a state of the refrigeration system; transmit a command over said serial communications bus; and execute a plurality of algorithms to control the refrigeration compartment and the quick chill/thaw pan based on the command transmitted over said serial communications bus. 4. A control system in accordance with claim 1 wherein said controller is configured for user selection of a plurality of said quick thaw mode using said HMI board. 5. A control system in accordance with claim 1 wherein said controller is configured for user selection of a plurality of said quick chill mode using said HMI board. 6. A control system in accordance with claim 1 wherein said HMI board comprises at least one light emitting diode (LED) for indicating operation of at least one of said quick thaw mode and said temperature zone mode. 7. A control system in accordance with claim 1 wherein said HMI board comprises at least one light emitting diode (LED) for indicating operation of said quick chill mode. 8. A control system for a refrigeration system, the refrigeration system including at least one refrigeration compartment, a quick chill/thaw pan located in the refrigeration compartment, an air handler including a heater element, a damper, a fan for supplying air to the quick chill/thaw pan, and a temperature sensor for detecting a temperature of the air handler, said control system comprising: an electronic controller comprising a main board, a temperature adjustment board, a dispenser board, and a serial communications bus, said main board electrically connected to said temperature adjustment board and said dispenser board through said serial communications bus for controlling the temperature of the refrigeration compartment and the quick chill/thaw pan; and a human machine interface (HMI) board comprising a plurality of input selection keys, said controller electrically connected to said HMI board and configured for user selection of a quick chill mode, a quick thaw mode, and a turbo cool mode, wherein said turbo cool mode reduces a temperature of air inside the refrigeration compartment, wherein said controller is configured to control an operating speed of the fan based on a detected temperature of the air handler, said controller further configured to energize the heater element in order to maintain a temperature in the quick chill/thaw pan and open the damper to circulate air between the air handler and the quick chill/thaw pan when the heater element is energized. 9. A control system in accordance with claim 8 wherein said input selector keys comprising at least one of a quick chill key, a quick thaw key, and a turbo cool key. 10. A control system in accordance with claim 8, said electronic controller configured to: accept a plurality of inputs including at least a refrigeration compartment temperature and an input indicating operation of one of said quick chill mode, said quick thaw mode, and said turbo cool mode; determine a state of the refrigeration system; transmit a command over said serial communications bus; and execute a plurality of algorithms to control the refrigeration compartment and the quick chill/thaw pan based on the command transmitted over said serial communications bus. 11. A control system in accordance with claim 8 wherein said controller is configured for user selection of a plurality of quick thaw modes using said HMI board. 12. A control system in accordance with claim 8 wherein said controller is configured for user selection of a plurality of quick chill modes using said HMI board. 13. A control system in accordance with claim 8 wherein said HMI board comprises at least one light emitting diode (LED) for indicating operation of at least one of said quick thaw mode and said turbo cool mode. 14. A control system in accordance with claim 8 wherein said HMI board comprises at least one light emitting diode (LED) for indicating operation of said quick chill mode.
