If you fi nd that the temperature displayed on the

temperature where the thermostat is located, this
offset function compensates for the difference.
The thermostat will apply an offset between what
temperature the thermostat is measuring versus the
temperature that is displayed.
TEMPERATURE OFFSET
The Temperature Offset function allows for
calibration of the temperature sensor.
Adjust the Temperature Offset settings using the
up/down arrow buttons. Press the center button to
save changes.

5.6.4.2 SMART RECOVERY
Smart recovery is a feature designed to save
energy by gradually adjusting temperatures. When
it is time for a program schedule temperature
change, smart recovery begins working in
advance, turning the system on and off as needed
to slowly adjust the indoor temperature so that
it reaches the program temperature setpoints at
the time you set. Rather than waiting to start the
equipment until the program time has occurred.
Adjust the Smart Recovery setting using the up/
down arrow buttons. Press the center button to
save changes.
• Events Per Day (default On): options: ON,
OFF
NOTE 1: The thermostat must be confi gured for
programmable mode by installer to access the
Smart Recovery setting.
NOTE 2: Auxiliary heat will not be used during
Smart Recovery.
5.6.4.3 EVENTS PER DAY
NOTE: The thermostat must be confi gured for
programmable mode by installer to access the
Events per Day setting.
Events Per Day sets the number of program
schedule events for each day. An event is a period
of time scheduled with a certain heat setpoint, cool
setpoint, and fan mode.
