Abstract
A heating control system including an air circulation fan, a heating unit, a memory, and a microprocessor. The microprocessor is configured to operate the air circulation fan at a first speed and the heating unit in a first configuration where less than all of the burners are active. The microprocessor is further configured to determine a first temperature difference, compare the first temperature difference to a first temperature difference threshold, and transition the air circulation fan from the first speed to a second speed when the first temperature difference is less than the first temperature difference threshold. The microprocessor is further configured to determine a second temperature difference, compare the second temperature difference to a second temperature difference threshold, and transition the air circulation fan from the second speed to a third speed when the second temperature difference is less than the second temperature difference threshold.
