4. Press increase ▲ or decrease ▼ key to adjust the
temperature setting, if desired. (Example: Heat 54° =
heating equipment will operate when the room
temperature is below 54°F)
NOTE: When the System is set for Auto (select
models), both heat and cool settings are
needed. If the System is set for Heat, only the
Heat setpoint is needed or if Cool is selected,
only the Cool setpoint is needed.
5. Press Heat/Cool Settings to change between heat and
cool settings.
6. Press increase ▲ or decrease ▼ key to adjust the
temperature setting, if desired. (Example: Cool 84° =
cooling equipment will operate when the room
temperature is above 84°F)
NOTE: In this example, the thermostat uses the Hold setting
for eighteen days and returns to the daily programs
at the Return period start time. The temperature
settings are heating 54°F and cooling 84°F. Only the
heating temperature is used because the System is
set for Heat. The thermostat will use both the heating
and cooling temperature settings when the System
is set to Auto (select models).
IMPORTANT
If the Hold needs to be canceled before the
designated time, press Run Program to return to the
program.
