The method of claim 1, wherein said processing unit monitors said operational condition data for a pre-determined period after receiving operational condition data that is inconsistent with said pre-determined range of acceptable operational condition values, and said barrier is positioned in said closed position after said pre-determined period if said operational condition data is inconsistent with said pre-determined range of acceptable operational condition values for the pre-determined period. 3. The method of claim 2, further comprising activating said barrier motor to re-position said barrier in an open position in which it is retracted from said open side of said temperature controlled compartment, wherein said processing unit activates said barrier system motor to retract said barrier if said operational condition data becomes consistent with said pre-determined range of acceptable operational condition values during the pre-determined period. 4. The method of claim 2, further comprising sending an error message to a remote computer when said operational condition data is inconsistent with said pre-determined range of acceptable operational condition values for said pre-determined period. 5. The method of claim 1, wherein said at least one component is selected from the group consisting of a temperature sensor, a compressor, and a power supply. 6. The method of claim 1, further comprising transmitting said operational condition data to a remote computer. 7. The method of claim 1, further comprising sending an error message to a remote computer when said operational condition data is inconsistent with said pre-determined range of acceptable operational condition values. 8. The method of claim 1, wherein said at least one operational condition data is temperature sensor data. 9. The method of claim 8, wherein said processing unit continues to monitor said temperature sensor data for a pre-determined period after receiving temperature sensor data that is inconsistent with said pre-determined range of acceptable operational condition values, and said barrier is positioned in said closed position after said pre-determined period if said temperature sensor data is inconsistent with said pre-determined range of acceptable temperature sensor data values for the pre-determined period. 10. The method of claim 1, wherein said at least one operational condition data is a power supply data to said open air control unit. 11. The method of claim 10, wherein said processing unit continues to monitor said power supply data for a pre-determined period after receiving power supply data that is inconsistent with said pre-determined range of acceptable operational condition values, and said barrier is positioned in said closed position after said pre-determined period if said power supply data is inconsistent with said pre-determined range of acceptable power supply values for the pre-determined period. 12. The method of claim 11, further comprising monitoring said power supply data for a second pre-determined period after said barrier is positioned in said closed position, and opening said barrier if said power supply data becomes consistent with said pre-determined range of acceptable power supply values during said second pre-determined period. 13. The method of claim 1, wherein said at least one operational condition data is temperature control unit data. 14. The method of claim 13, wherein said processing unit continues to monitor said temperature control unit data for a pre-determined period after receiving temperature control unit data that is inconsistent with said pre-determined range of acceptable temperature control unit data values. 15. The method of claim 14, wherein said barrier is positioned in said closed position after said pre-determined period if said temperature control unit data is inconsistent with said pre-determined range of acceptable temperature control unit values for the pre-determined period. 16. The method of claim 13, wherein said processing unit monitors temperature data taken by at least one temperature sensor in said open air unit for a pre-determined period after receiving temperature control unit data that is inconsistent with said pre-determined range of acceptable temperature control unit data values. 17. The method of claim 16, wherein said barrier is positioned in said closed position after said pre-determined period if said temperature data is inconsistent with a pre-determined range of acceptable temperature data values for the pre-determined period. 18. The method of claim 16, wherein said processing unit resets a timer for said pre-determined period if said temperature data remains within said pre-determined range of acceptable temperature data values for the pre-determined period, and said processing unit monitors said temperature for said pre-determined period for a second time. 19. The method of claim 1, further comprising locking said barrier in said closed position over said open side of said temperature-controlled compartment, wherein said processing unit is in electronic communication with a locking mechanism for locking said barrier in said closed position over said open side. 20. A method of deterring consumers from removing items from an open-air display unit, comprising: a. monitoring at least one environmental condition inside a temperature-controlled compartment of said open-air refrigeration unit with at least one sensor for detecting environmental conditions in said open-air refrigeration unit, wherein said at least one sensor is in electronic communication with a processing unit, which collects and analyzes sensor data from said at least one sensor;b. monitoring at least one operational condition data of at least one component of said open-air refrigeration unit, wherein said processing unit is in electronic communication with said at least component and said processing unit collects and analyzes said at least one operational condition data from said at least one component;c. said processing unit comparing said sensor data to at least one pre-determined acceptable set of environmental conditions stored in an internal memory of said processing unit;d. said processing unit comparing said data to at least one pre-determined acceptable set of operational condition data stored in said internal memory of said processing unit; ande. said processing unit activating a motor mechanically connected to said barrier to move said barrier to a closed position over an open portion of a temperature-controlled compartment when said sensor data is inconsistent with said pre-determined acceptable set of environmental conditions or when said operational condition data is inconsistent with said pre-determined acceptable set of operational condition data. 21.
