An adaptive microprocessor control system and method provide a low heat mode and a high heat mode of a heating cycle in a furnace dependent upon the performance of the previous heating cycle. The duration of the low heat mode and subsequent high heat mode period is a function of the previous low heat mode duration, previous high heat mode duration, and the time period between the end of the previous heating cycle and the beginning of the next heating cycle. The control and method utilize a single-stage thermostat for providing the dual rates of heating.

A method for selectively providing a low heat mode and a high heat mode of a heating cycle in a furnace as a function of a previous heating cycle, comprising the steps of: storing a previous time period of operation of a low heat mode and a previous time period of operation of a high heat mode of a previous heating cycle, determining the existence of a heating load to be satisfied, recalling the stored time period of the previous high heat mode, providing a low heat mode for a selected first time period dependent upon the stored time period of the previous high heat mode, and terminating the low heat mode if the heating load is satisfied during the selected first time period.
