Abstract
A digital thermostat includes a microcontroller and a single rotary encoder switch having an adjusting shaft and a knob connected to the shaft. The shaft of the switch is rotatable by the knob to a plurality of discrete angular positions, each of which enables the switch to provide a unique signal to the microcontroller. Each unique signal is interpreted by the microcontroller so as to establish a desired set point temperature. Each discrete angular switch position also effects a visual display, through an opening in the thermostat cover, of the desired set point temperature.
