Heating Fan Optimization (Furnace)
Once a heating cycle ends the fan will continue to run for this time period. This is
also known as the blower off delay, for heating. The longer the time, the more heat
is pulled out of the heat exchanger but the cooler the temperature is at the end of the
cycle. The actual blower off delay will always be the longest of the equipment
setting or the thermostat setting.
