crease the setting.
HIGH AMBIENT ELECTRIC HEAT LOCKOUT SELEC-
TION (08) — If DIP switch A is set to ON (heat pump) and
DIP switch C is set to OFF (an outdoor temperature sensor is
present), electric heat can be locked out if the outdoor ambient
temperature rises above the user-defined value. Also, Configu-
ration 05 (Thermostat Sensor Connection Usage) must be set
to "od." Temperatures of 15 to 55 F (in 5-degree increments)
can be selected. The lockout can also be disabled. The default
is OF (disabled). Emergency Heat mode disables this func-
tion. Use the Up and Down buttons to increase or decrease the
setting.
LOCAL TEMPERATURE SENSOR CALIBRATION
(13) — The local Temperature Sensor Calibration is an offset
which is added or subtracted from the local temperature sensor
reading. The range of acceptable values is –5 to 5 F. The
default is 0° F (no offset).
To determine of an offset is required, compare the tempera-
ture reading on the thermostat to an accurate thermometer.

Adjust the offset (+ or –) until the thermostat temperature
matches room temperature.
OVERRIDE HOURS (18) — The Override Hours configura-
tion determines the number of hours that set point override will
last. The range of acceptable values is 1 to 6. The default is 3.
Set point override is activated by pressing the Occupied button
or by changing the set point with the Up or Down buttons. If
the schedule changes while the override time is still active, the
override is cancelled.
REMOTE TEMPERATURE SENSOR CALIBRATION
(19) — The Remote Temperature Sensor Calibration is an
offset which is added or subtracted from the remote tempera-
ture sensor reading. The range of acceptable values is –5 to
5 F. The default is 0° F (no offset).
To determine if an offset is required, compare the
remote temperature reading on the thermostat to an accurate
thermometer placed near the remote sensor. Adjust the offset
(+ or –) until the thermostat temperature matches the measured
temperature.
