19 SECOND STAGE DIFFERENTIAL
Second stage temperature differential determines when
the equipment advances from first to second stage. If the
temperature differential between indoor temperature and
setpoint exceeds the second stage temperature differential,
the equipment activates second stage heating or cooling.
Press the NEXT key to select Option 12 and the Up
or Down key to set the second stage temperature
differential. If the first stage temperature differential is
greater than third stage temperature differential, first
stage differential will automatically be incremented.
Note: Each stage differential is set at the desired number
of degrees from the setpoint not the previous stage.

20 THIRD STAGE DIFFERENTIAL
Third stage temperature differential determines when
the equipment advances from second to third stage.
Setting the differential temperatures the same for
second stage and third stage turns second and third
stage on at the same time.
Press the NEXT key to select Option 13 and the
Up or Down key to set the third stage temperature
differential. The third stage temperature differential
cannot be set below the second stage differential.
21 STAGE TIMING
The Staging Override Time will turn on the next stage
even though the temperature differential has not been
reached.
Press the NEXT key to select Option 14 and the Up or
Down key to set the stage timing.

CALIBRATING THE TEMPERATURE
SENSOR OFFSET
Typically, it is not necessary to adjust the temperature
calibration offset from the factory setting. If calibration is
necessary, a high quality electronic digital thermometer
must be used. Place the thermometer sensor probe next
to the thermostat sensor and allow five minutes before
comparing the temperature readings.
Press and hold the MENU key until the calibration
screen appears as shown. Use the Up and Down keys
to adjust the temperature calibration offset. Press the
ENTER key to save the setting and return to normal
thermostat operation.
