SETTING THE FAN OPERATION JUMPER

Depending on your home's heating system, you may need to change the jumper setting for the fan operation.

The jumper is located at the lower right-hand side of the back of the thermostat.

l HG – Use this setting for gas or oil-fired furnaces.

This setting allows the fan operation to be controlled

by the heating system; not the thermostat.

This is the correct setting for most systems.

l HE – Use this setting for electric powered furnaces.

With this setting, the thermostat will turn on the fan

immediately with the heating system.

The jumper is pre-installed in the 'HG' position as a factory default.

So there is no need to change the jumper if this is the correct setting.

To change the jumper setting, pull out the small black rectangular block and align it to the new position and

push it in fully.
