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 .

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 .

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 .

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
Set To
to adjust the temperature calibration offset . Press the
ENTER key to save the setting and return to normal
thermostat operation .
