ABSTRACT:
An electronic thermostat operative to be connected to a furnace or other temperature modifying apparatus, to control its state of operation, includes means for generating a desired temperature set point signal and means for measuring ambient temperature on the thermostat. When the ambient temperature falls below the set point the furnace is energized for a predetermined period of time. The time of energization is increased or decreased by a small increment after each heating cycle depending upon magnitude of the temperature increase which occurred at the thermostat as a result of the heating cycle in order to adaptively achieve a predetermined temperature increase during the heating cycle and the thermal overshoot period which occurs following de-energization of the furnace.
In alternative embodiments of the invention the period of time in which the furnace is de-energized between heating cycles is controlled by a timer and adaptively modified in a similar manner, and the time delay between furnace energization and initiation of the blower at the beginning of a heating cycle and de-energization of the blower after the end of the heating cycle are similarly adaptively modified.
