This ISU is only displayed if ISU 2010 is set
for Electric Forced Air or Hot Water Fan Coil.
The thermostat automatically energizes the
fan in heat when running a heat pump.
The thermostat automatically allows the
system to run the fan in heat when set for
gas or oil forced air systems. For radiant
systems (excluding hot water fan coil) the
thermostat does not energize fan in heat.
