1) System Configuration - Selects SS (Single Stage) or HP
(Heat Pump) operating mode. Default configuration is SS.
For Heat Pump operation choose HP.
2) Select CS (Cool Savings™) - With Cool Savings™
enabled, the thermostat will make small adjustments to
the Setpoint temperature during periods of high demand
to reduce cooling system running time and save energy.
When the cooling system has been running for more than
20 minutes, humidity in the home will be lower and a higher
setpoint temperature will feel comfortable. After 20 minutes
of run time, the thermostat will start increasing the setpoint
temperature in steps of less than one degree as the system
continues to run. These adjustments will eventually cause
the system to satisfy the thermostat and turn the system off
to reduce the energy consumption. When the Cool Savings
feature is active and making adjustments, the display will
show "Save". The amount of the adjustments to the setpoint
temperature is dependent on the Cool Savings value that
is set, 1 being the least adjustment and 6 being the most
adjustment. With this feature set to OFF, no change will
occur when the cooling system is continuously running
during the periods of high demand. Periods of high demand
will normally occur during the late afternoon and early
evening on the hottest days of the summer.
3 & 4) Select Cycle Rate Selection - The factory default
setting for Single Stage Heat is Medium Cycle (ME). For
Single Stage Cool the default setting is fast (FA). To change

5) Select Compressor Lockout CL OFF or ON - Selecting
CL On will cause the thermostat to wait 5 minutes between
cooling cycles. This is intended to help protect the
compressor 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
lockout feature is already present in their system. When the
thermostat compressor time delay occurs, it will flash the
setpoint for up to five minutes.
6) Select Backlight Display - The display backlight improves
display contrast in low lighting conditions. When the "C"
terminal is connected, selecting backlight CdL On will keep
the light on continuously. Select backlight OFF will turn the
light on momentarily when any key is pressed. When the
"C" terminal is not connected, regardless of the backlight
selection, the light will be on momentarily when any key is
pressed.
7) Select Temperature Display Adjustment 4 LO to 4 HI -
Allows you to adjust the room temperature display up to 4°
higher or lower. Your thermostat was accurately calibrated
at the factory but you have the option to change the display
temperature to match your previous thermostat. The
current or adjusted room temperature will be displayed on
the display.
8) Select F° or C° Readout - Changes the display readout to
Celsius or Fahrenheit as required.
9) Select Filter Replacement Reminder and Set Run Time
Select the "Change Filter" reminder On or OFF. If selected
On, press
and
1975 hours in 25 hour increments. In a typical application,
200 hours (default) of run time is approximately 30 days.
After the selected time of blower operation, the thermostat
will display "Change Filter" as a reminder to change or
clean your air filter. When "Change Filter" is displayed,
press the
and
restart the time to the next filter change. A selection of OFF
will cancel this feature.
