Abstract: A furnace of a heating, ventilation, and/or air conditioning (HVAC) system includes a heat exchange tube configured to receive a working fluid from a burner and a modulating valve fluidly coupled to the burner. The modulating valve is configured to regulate an amount of fuel supplied to the burner to generate the working fluid. The furnace also includes a blower configured to draw the working fluid through the heat exchange tube, a motor drive configured to adjust a speed of the blower, and a controller configured to adjust a position of the modulating valve and to control the motor drive to adjust the speed of the blower based on a temperature of air discharged from the HVAC system.

Abstract: A heating, ventilation, and/or air conditioning (HVAC) unit includes a first sensor disposed adjacent to an inlet of an evaporator configured to receive an airflow. The HVAC unit includes a second sensor disposed adjacent to an outlet of a reheat coil positioned downstream of the evaporator and configured to expel the airflow. The HVAC unit also includes a controller configured to regulate operation of a modulating reheat valve to adjust flow of a working fluid in thermal communication with the airflow to control a difference between a measurement of the first sensor and a measurement of the second sensor.
