error will be displayed.

OPTION 13—ROOM TEMPERATURE OFFSET
This option allows calibration (or deliberate miscalibration) of
room temperature sensor. There are various reasons why the home
owner may want to have displayed temperature adjusted to a
higher or lower value. The selected number is the number of
degrees, plus or minus, which will be added to the actual
temperature. The number can range between -5 and +5. Factory
default is 0. This adjusted value will be used as actual temperature
for both display and control action. For example, if 2 is selected,
72°F actual will read 74°F. If setpoint is 72, the room will control
to an actual value of 70 which will be displayed and acted upon as
if it were 72. The effect is that a positive number selection will
make the room temperature lower and vice versa. This thermostat
is factory calibrated within an accuracy of plus or minus 1°F, so
this adjustment will provide the best accuracy when set to 0.
TO SELECT:
1. Enter configuration mode (if not already there).
2. Use up and down buttons to display Option 13. The SET icon
should be off.
3. Press MODE button once. The SET icon will come on. The

button are used to move between OFF, HEAT, and EHEAT (in
