ABSTRACT:
An electronic thermostat including a stored program of desired temperatures and predetermined maximum and minimum temperatures. The stored program of desired temperatures is selectable as either a program of heating temperatures or a program of cooling temperatures. When in the heating mode controlled by a program of desired heating temperatures, the cooling mode is entered and the air conditioner is energized if the actual temperature exceeds a predetermined temperature. The control temperature in this cooling mode has a predetermined relationship to the programmed temperature in the heating mode. Similarly, if the thermostat is in a cooling mode and the actual temperature falls below another predetermined temperature which is lower than the first predetermined temperature, then the thermostat enters the heating mode and energizes the furnace. The control temperature in this case bears a predetermined relationship to the programmed cooling temperature. In a further embodiment, the air conditioner is actuated if the actual temperature exceeds a predetermined maximum temperature regardless of the mode of the thermostat. In a still further embodiment, the heater is actuated when the actual temperature falls below a predetermined minimum temperature regardless of the mode of the thermostat.
