Abstract
A universal food holding cabinet has multiple compartments, the temperatures of which are under software control by microprocessors or microcontrollers located on power supply circuit boards for corresponding compartments. Each compartment can have different temperature control requirements with different requirements being met by different programs in different processors, or different operating parameters for the same program. The cabinet is configured to prevent the power supply boards from being installed incorrectly, to provide an address to a power supply circuit board when it is installed and by which a power supply circuit can be addressed by a master controller to receive downloads of executable instructions and/or data.
