A microcomputer controlled digital thermostat has separate, independent registers for storing heating control information and cooling control information. On a periodic basis, the microcomputer determines whether the furnace should be turned on, based upon a temperature signal indicative of room temperature, a time-of-day value indicative of the present time of day, and the stored heating control information. If the furnace is already off and the microcomputer determines that it should remain off, the microcomputer then determines whether air conditioning is needed, based upon the temperature signal, the time-of-day value, and the stored cooling control information.

Temperature control apparatus for providing heating control signals for controlling heating apparatus and cooling control signals for controlling cooling apparatus, the temperature control apparatus comprising: temperature sensing means for providing a temperature signal indicative of a sensed temperature; time-of-day means for providing a time-of-day value; means for storing heating control information including heating time values and associated heating control temperature values; means for storing cooling control information; and control means for providing the heating control and cooling control signals, wherein the control means periodically makes a heating control determination, based upon the time-of-day value, the temperature signal, and the stored heating control information, to provide a heating control signal which (a) turns the heating apparatus on, (b) turns the heating apparatus off, (c) leaves the heating apparatus on, or (d) leaves the heating apparatus off; and wherein only if the heating control determination leaves the heating apparatus off, the control means makes a cooling control determination based upon the time-of-day value, the temperature signal, and the cooling control information, to provide a cooling control signal which (e) turns the cooling apparatus on, (f) turns the cooling apparatus off, (g) leaves the cooling apparatus on, or (h) leaves the cooling apparatus off.
