4. There will be insulation behind the knockout on the inside of
the unit. Cut an “X” into the insulation as shown in Figure 1.
5. Snap in the webbed grommet into the resulting hole in the duct
panel.
6. Remove the door from the housing assembly. Place the plug
of the thermostat through the grommet and through the hole
cut into the insulation into the inside of the unit.
7. With the cutting screws shipped with the kit, mount the hous-
ing to the duct panel using the locating dimples on the panels.
When mounted, the large hole in the top right hand corner of
the housing should surround the webbed grommet and the
housing should be flush against the duct panel.
8. Locate the outdoor thermostat harness inside the blower com-
partment. Remove the jumper plug and connect the plug from
the thermostat to the plug inside the blower compartment.
Place the jumper plug with the literature of the unit and keep in
case servicing is needed later.
9. Set the outdoor thermostat to the desired level using a flat
head screw driver (see Figure 2). The setting will determine
the temperature at which the unit will switch from mechanical
heat with the heat pump to gas heat using the gas furnace. In
most cases, it is recommended that the setting be in the range
of 35°F – 40°F depending on the cost of local utilities.
Set the thermostat
by lining the small tick mark
on the dial with the desired temperature.

IMPORTANT NOTE: If the housing is in a location where it will be in
direct sunlight, the temperature inside the housing could be 5°F -
10°F higher than the ambient outside of the box. Take this into
consideration when setting the thermostat in these applications.
10. Once the thermostat is set, replace the door to the housing
and to the blower compartment.
