BATTERY LOCATION  
ATTACH THERMOSTAT BASE TO WALL  
“AA” Alkaline Batteries  
1. Remove the packing material from the thermostat. Gently  
pull the cover straight off the base. Forcing or prying on the  
thermostat will cause damage to the unit.  
2. Place base over hole in wall and mark mounting hole  
locations on wall using base as a template (see Fig.1).  
Two “AA” alkaline batteries are installed in your thermostat  
with a battery tag to prevent power drainage. Prior to use,  
open the battery door and remove the battery tag. To open,  
pull the battery door as shown by the arrow and lift open. The  
two “AA” batteries will operate all functions or maintain time  
and continuously display the temperature during a loss of AC  
power. Installed batteries will also allow programming prior to  
installation. To replace batteries, pull the battery door shown  
by the arrow and lift open. Using the polarity indicated inside  
the battery door, insert the batteries. To close the battery door,  
swing the door down while pulling in the direction of arrow.  
Once fully down, snap the door back into position.  
3. Move base out of the way. Drill mounting holes.  
4. Push wires through opening in thermostat base.  
5. Fasten base loosely to wall using two mounting screws.  
Place a level against bottom of base, adjust until level,  
and then tighten screws. (Leveling is for appearance only  
and will not affect thermostat operation.) If you are using  
existing mounting holes, or if holes drilled are too large and  
do not allow you to tighten base snugly, use plastic screw  
anchors to secure subbase.  
6. Connect wires to terminals on base using appropriate  
wiring schematic (see figs. 2 through 4).  
Thermostat can be powered by system AC power or Battery. If

O/B TERMINAL SWITCH SELECTION  
The O/B switch on this thermostat is factory set to the “O”  
position. This will accommodate the majority of heat pump  
applications, which require the changeover relay to be  
energized in COOL. If the thermostat you are replacing or the  
heat pump being installed with this thermostat requires a “B”  
terminal, to energize the changeover relay in HEAT, the O/B  
switch must be moved to the “B” position.

is displayed, the  
batteries should be replaced before leaving. When less than  
two months of battery life remain, the setpoint temperature will  
offset by 10 degrees (10 degrees cooler in Heat mode / 10  
degrees warmer in Cool mode). If offset occurs, the normal  
setpoint can be manually reset with

automatically start the heating system at 5:00 AM, so that the  
programmed temperature of 70°F is reached by about 6:00  
AM.  
ENERGY MANAGEMENT RECOVERY  
(EMR)  
When the EMR feature is activated the thermostat’s  
microcomputer calculates the time it will take to change the  
room temperature to the next heat or cool program setting.  
Then the thermostat will start the system before the next  
programmed period so that the desired temperature is reached  
at or near the beginning of the period (the thermostat calculates  
15 minutes for every 1°F temperature change). This feature  
provides better efficiency by allowing gradual temperature  
changes.  
If the overnight room temperature drops only to 68°F, the  
thermostatwillstartthesystemat5:30toreachtheprogrammed  
temperature of 70°F at 6:00.  
The thermostat is shipped with the EMR feature active, which  
means that the thermostat will start the heating system before  
the beginning of the next program period.  
To deactivate the EMR function, see the Configuration menu  
on Page 5).The thermostat will then wait until the programmed  
time to start the system for a temperature change.  
For example: The thermostat is programmed to provide an  
overnight heating temperature of 66°F, and during the next  
program period, beginning at 6:00 AM, the programmed  
temperature is 70°F. With EMR activated, the thermostat will

3) Select Energy Management Recovery  
-
Energy  
1) System Configuration - Selects SS (Single Stage) or HP  
(Heat Pump) operating mode. Default configuration is SS.  
For Heat Pump operation choose HP.  
Management Recovery (E) On enables the thermostat  
to start heating or cooling early to make the building  
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: E On is  
selected and your heating is programmed to 65o at night  
and 70o at 7AM. If the building temperature is 65o, the  
difference between 65o and 70o is 5o. Allowing 5 minutes  
per degree, the thermostat Setpoint will change to 70o at  
6:35 AM. Cooling allows more time per degree, because it  
takes longer to reach set temperature.  
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.  
4 & 5) 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  
cycle rate, press the  
and  
buttons.

INSTALLER/CONFIGURATION MENU  
6) 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.  
8) 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.  
9) Select F° or C° Readout - Changes the display readout to  
Celsius or Fahrenheit as required.  
7) 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.  
10) Select Filter Replacement Reminder and Set Run Time  
Select the “Change Filter” reminder On or OFF. If selected  
On, press RUN/HOLD to select the time period from 25 to  
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 RUN/HOLD button to clear the display and restart  
the time to the next filter change. A selection of OFF will  
cancel this feature.
