Step 6—Final Settings
1. Assuming the system is to be left in operation after the
installation is complete, use MODE button to select between
HEAT, COOL, EHEAT, or AUTO to provide the desired
operation of heating, cooling, or both.
2. The default set points and programmed schedule conform to
the Energy Star requirements of the U.S. Department of
Energy for both heating and cooling. These provide energy
saving temperature settings.
3. Turn on HOLD if fixed set points are to be used. If the
programmed schedule is to be used, make sure the HOLD icon
is off.
4. For further information on temperature selection and program-
ming, refer to Homeowner's Guide.
5. If AUTO mode is to be used, be sure both heat and cool set
points are properly adjusted.
6. The FAN button may be used to select between AUTO (fan on
only with equipment) and ON (fan on continuously) fan
modes.
