1) Select FA or SL (Fast or Slow) Heating Cycle Rate—The
FA setting is frequently used for gas, oil or electric heat. The
SL setting produces a longer heating cycle which is normally
for hot water or steam (hydronic) systems. Both settings
produce very accurate temperature control and can be set to
your personal preference. FA cycles the system just under
1
°
F and the SL setting cycles at approximately 1.5F
°
.
2) Select backlit display—The display backlight improves
display contrast in low lighting conditions. Selecting backlight
ON will keep the light on for a short period of time after any
key is pressed. Selecting OFF will keep the light off.

stat to start heating or cooling early to make the building
The only way to restore this feature is to complete a software

temperature reach the program setpoint at the time you
specify. Heating will start 5 minutes early for every 1
°
of
temperature required to reach setpoint.
Example: You select EMR and have your heating pro-
grammed to 65
°
at night and 70
°
at 7 AM. If the building
temperature is 65
°
the difference between 65
°
and 70
°
is 5
°
.
Allowing 5 minutes per degree the thermostat setpoint will
change to 70
°
at 6:35 AM. Cooling allows more time per
degree because it takes longer to reach temperature.
4) Select Compressor Lockout LOC OFF or ON—Selecting
LOC ON will cause the thermostat to wait 5 minutes before
turning on the compressor if the heating and cooling system
loses power. It will also wait 5 minutes minimum between
cooling cycles. This is intended to help protect the compres-
sor from short cycling. Some newer compressors already
have a time delay built in and do not require this feature. Your
compressor manufacturer can tell you if the feature is already
present in their system. When the compressor time delay
occurs it will flash the for about five minutes then turn on
the compressor.
5) Select Temperature Display Adjustment 4 LO to 4 HI—
Allows you to adjust the room temperature display 4
°
higher
or lower. Your thermostat was accurately calibrated at the
factory but you have the option to change the display tem-
perature to match your previous thermostat.

PROGRAMMING YOUR THERMOSTAT
This section will help you plan your thermostat’s program to meet
your needs. For maximum comfort and efficiency, keep the
following guidelines in mind when planning your program.
• When heating (cooling) your building, program the tempera-
tures to be cooler (warmer) when the building is vacant or
during periods of low activity.
• During early morning hours, the need for cooling is usually
minimal.
Look at the factory preprogrammed times and temperatures shown
below. If this program will suit your needs, simply press the RUN
button to begin running the factory preset program.
If you want to change the preprogrammed times and tempera-
tures, follow these steps.
Determine the time periods and temperatures for each day
programs. You must program four periods for each day program.
