Abstract
A programmable thermostat employing means for sensing the ambient temperature on the thermostat, a clock for generating digital electrical signals representative of real time, a programmable digital memory for retaining a schedule of times and temperature ranges for a particular repetitive time cycle, display means for indicating selected information including programming mode, time, and temperature conditions during the programming and operation of the device, and control means for interrogating the current temperature range in the times-temperatures schedule, determining whether the ambient temperature on the thermostat is within that range, and generating a control signal to the furnace or air conditioner when appropriate.
