Abstract
A heating system comprising an air circulation fan, a heating unit, a memory that is operable to store a temperature map, 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. When the heating unit is in the first configuration, the heating unit is configured to achieve a first temperature and such that less than all of the burners are active. The microprocessor is also configured to receive a temperature set point and to determine a second speed for the air circulation fan using the temperature set point and the temperature map in response to receiving the temperature set point. Further, the microprocessor is configured to transition the air circulation fan from the first speed to the second speed in response to determining the second speed.
