Abstract
A heating control device comprising input/output ports, a memory, and a microprocessor. The microprocessor is configured to transmit a first electrical signal to operate an air circulation fan at a first speed and a 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 obtain a return air temperature, obtain a room air temperature, and determine a temperature difference between the return air temperature and the room air temperature. The microprocessor is further configured to compare the temperature difference to a temperature rise threshold and transmit a second electrical signal to transition the air circulation fan from the first speed to a second speed to achieve a second temperature rise that is less than the first temperature rise when the temperature difference is greater than the temperature rise threshold.
