Title: Subbase programmable control system

Abstract: A control unit such as a thermostat has a subbase which mounts on the surface holding the control unit and has electrical terminals for connecting to an operating unit. A controller is designed to mechanically attach and electrically interface to the subbase. The subbase has a memory unit which can record a number of different digital values. Each of these digital values corresponds to an operating unit requiring a different configuration of control algorithms. The controller receives the value recorded in the subbase memory unit and configures its control algorithms according to the value provided from the memory unit.
