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 to achieve a first temperature rise where less than all of the burners are active. The microprocessor is further configured to compare the first temperature rise to a first temperature rise threshold and transition the air circulation fan to a second speed to achieve a second temperature rise when the first temperature rise is less than the first temperature rise threshold. The microprocessor is further configured to compare the second temperature rise to a second temperature rise threshold and transition the air circulation fan to a third speed when the second temperature rise is greater than the second temperature rise threshold.
