    摘要: A furnace system for a heating, ventilation, and air conditioning (HVAC) system includes a furnace controller configured to determine a rolling average furnace run time of the furnace system based on a plurality of previous run cycles of the furnace system. The furnace controller is configured to segment the rolling average furnace run time into a plurality of operational time periods, wherein each operational time period is associated with a distinct fire rate of a plurality of distinct fire rates the furnace system. The furnace controller is also configured to operate the furnace system to sequentially implement the plurality of distinct fire rates associated with the plurality of operational time periods.

    摘要: A heater for heating air includes an inlet, an outlet, and an air duct between the inlet and the outlet. A fan and a heating element are positioned in the air duct. A first temperature sensor is positioned at or near the inlet and configured to measure a first temperature of ambient air at the inlet. A second temperature sensor in positioned in the air duct and configured to measure a second temperature of heated air flowing through the air duct. The heater is configured to control heating power and fan speed based on measurements taken by the first and second temperature sensors.
