Setting Temperature Differentials
The default settings for the first and second stage differentials are compatible
with most systems and applications. This is normally set at time of installation and
usually does not require any modification under normal operating conditions. If you
feel that your system is turning on too often, simply follow the instructions below.
NOTE: The temperature differential settings are the same for both the heating
and cooling systems.
Setting First Stage Differential
The default setting is 0.5˚ F (0.25˚ C). The room temperature must change .5˚ F
(0.25˚ C) from the set point temperature before the thermostat will initiate the
system in heating or cooling.
1. In normal operating mode, press and hold
the and buttons at the same time for 3
seconds. LCD display will show "
SET D1 X˚",
where " X" equals the ˚F / ˚C differential setting.
This is the current first stage differential setting.
2. Press the or buttons to set the first stage differential to your desired
setting of .5˚, 1˚, or 2˚ F (.25––displayed as .3˚, .5˚ or 1˚ C).

3. Press both the and buttons at the same time again to change the next
setting. For the model 3200, the next setting is the Second Stage Differential.
For the model 3000, the next setting is the Residual Cooling Fan Delay, or wait
5 seconds for the thermostat to return to the normal operating mode.
Setting Second Stage Differential (Model 3200 Only)
The default setting is 2˚ F (1.0˚ C). The room temperature must change 2˚ F
(1.0˚ C) in addition to the first stage differential setting before the thermostat will
initiate the second stage of the system in heating.
4. Press and hold the and buttons at the same
time again and the LCD display will show "
SET
D2 X˚", where "X" equals the ˚F / ˚C differential
setting. This is the current second stage
differential setting.
5. Press the or buttons to set the second stage differential to your desired
setting of 2˚, 3˚, 4˚, 5˚or 6˚ F (1˚, 1.5˚, 2˚, 2.5˚ or 3˚ C).
6. Press and hold the and buttons at the same time to change the residual
cooling fan delay, or wait 5 seconds for the thermostat to return to the
normal operating mode.
Setting Residual Cooling Fan Delay
The default setting is 60 seconds. During the
COOL mode of operation, the fan
will stay on for 60 seconds after the cooling system has reached the set point
temperature and has turned off the compressor. This improves system efficiency
during cooling operation.
1. The display will show "FAN SET XX", where
"
XX" is the fan delay time in seconds.
2. Press the or button to change the Residual
Cooling Fan Delay (0, 30, 60, or 90 seconds).
3. Press both the and buttons at the same time again to return to normal
operating mode or wait 5 seconds for the thermostat to return to normal
operating mode automatically.
NOTE: To erase all user program settings, gently press the RESET button using a
paper clip or a small pencil tip. This will return all thermostat settings to their
default values, erasing all program settings entered by the user.
