Step 4. Set Thermostat for Your Type of Heating System
IMPORTANT:
Setting your thermostat cor-
rectly for your type of heating
system allows it to maintain
accurate temperature control,
minimize swings in the tem-
perature of the room, and
efficiently run the fan.
a. Use the FUEL SWITCH
on the back of the thermostat
to set your new thermostat
for the type of fuel that your
heating system uses: F–
gas or oil, or E–electric.
NOTE: This setting enables
proper fan operation.
b. Use DIP switches 1 and 2
on the back of the thermostat
to set your new thermostat
for your type of heating sys-
tem. See the Heating System
Table on the next page to find
the correct settings.
NOTE: These DIP switches
are factory-set for a warm air,
gas, or oil heating system.
c. The thermostat is set to display the temperature in degrees Fahrenheit (°F). If you want to display the temperature
in degrees Celsius (°C), turn DIP Switch 3 to Off position.
d. You can install the batteries and program your thermostat now, or you can wait until the thermostat is mounted on
the wall. To install the batteries, see Step 7. To program the thermostat, see the Programming section.
