Adjusting the Differential (Also called
Swing or Cycle rate)
The differential is adjustable, a smaller
differential will cause more frequent
cycles andalarger differential will
cause fewer cycles. There are separate
differentials for heat and for cool. Follow
the steps below to adjust the differential
for heat or cool:
1.
Select HEAT or COOL with the system
switch.
2. Hold down the
+
and
-
keys
together for 3 seconds.
3.
Use the
+
or
-
key to adjust
the differential. The differential is
adjustable from ±0.2°F to ±2°F.
For example: A differential setting
of 0.5°F will turn the cooling on
at approximately 0.5°F above the
setpoint and turn the cooling off
at approximately 0.5°F below the
setpoint. The factory default for
cooling is 0.5°F and 0.4°F for heating.
4. Wait approximately 10 seconds for
the thermostat to return to normal
operation.
This feature allows the Installer to
change the calibration of the room
temperature display. For example: If the
thermostat reads 70° and you would like
it to read 72° then select +2. You can
adjust the room temperature display to
read -4°F to +4°F above or below the
factory calibrated reading. Follow the
steps below to adjust the temperature
reading:
1.
Select OFF with the system switch.
2.
Hold down the
+
and
-
keys
