2.4 Fan operation setting
NOTE: This setting is not applicable if there is no fan connected to
the G terminal.
The jumper is located on the back of the thermostat faceplate. It
determines how the fan operates when placed in Automatic mode.
• HG (factory setting): Leave the jumper in this position for gas or oil
heating systems. In this position, the heating system controls the
fan operation and activates the fan only when the plenum air is
sufficiently warm.
• HE: Place the jumper to this position for electric heating systems.
In this position, the thermostat activates the fan only when there is
a call for heat.
Incorrect jumper setting:
• Incorrect HE setting in a gas or oil heating system: When
heating starts, you will initially feel cold air coming out of the vents
as the fan is running before the furnace has enough time to heat
up the air.
• Incorrect HG setting in an electric heating system: The fan will
not run when heating is activated.
