INSTALLATION  
Battery Location  
WARNING  
!
2 "AA" alkaline batteries are included in the thermostat at  
the factory with a battery tag to prevent power drainage.  
Remove the battery tag to engage the batteries.  
To replace batteries, set system to OFF, remove thermostat  
from wall and install the batteries in the rear along the top of  
the thermostat (see Figure 1). For best results, use a  
premium brand "AA" alkaline battery such as Duracell® or  
Energizer®.  
Thermostat installation and all components of the  
control system shall conform to Class II circuits per  
the NEC code.  
Remove Old Thermostat  
A standard heat/cool thermostat consists of three basic parts:  
1. The cover, which may be either a snap-on or hinge type.  
2. The base, which is removed by loosening all captive screws.  
3. The switching subbase, which is removed by unscrewing  
the mounting screws that hold it on the wall or adapter  
plate. Before removing wires from old thermostat,  
label each wire with the terminal designation from  
which it was attached. Disconnect the wires from the old  
thermostat one at a time. Do not let wires fall back into  
the wall.

1. Pull the thermostat body off the thermostat 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.  
(for appearance only)  
Rear view of thermostat  
3. Move base out of the way. Drill mounting holes. If you  
are using existing mounting holes and the holes drilled  
are too large and do not allow you to tighten base snug-  
ly, use plastic screw anchors to secure the base.  
4. Fasten base snugly to wall using mounting holes shown  
in Figure 1 and two mounting screws. Leveling is for  
appearance only and will not affect thermostat operation.  
5. Connect wires to terminal block on base using  
appropriate wiring schematic (see diagram sheet  
37-6808).  
2 "AA" Batteries  
6. Push excess wire into wall and plug hole with a fire re-  
sistant material (such as fiberglass insulation) to prevent  
drafts from affecting thermostat operation.  
7. Carefully line the thermostat up with the base and snap  
into place.  
WIRINGCONNECTIONS  
Refer to equipment manufacturers' instructions for specific  
system wiring information. After wiring, see CONFIGURA-  
TION section for proper thermostat configuration.  
For wiring diagrams, see 37-6808.

5) System Switch Configuration (MS2/SS1) This  
thermostat is configured for Heat and Cool with Auto  
changeover default (Cool-Off-Heat-Auto). Can be  
configured as Heat & Cool (Cool-Off-Heat), or Heat Only  
(Off-Heat), or Cool Only (Cool-Off).  
On. Use  
or  
touch keys to select the feature, OFF.  
17 & 18) Select Automatic Schedule This feature allows  
programming a Comfort Temperatureinto all program  
periods with the Auto Schedule key. When Heat AS (for  
Heat mode) or Cool AS (for Cool mode) is selected On,  
the Auto Schedule feature is ready to be set. Off  
indicates that the feature is not ready to be used or a  
Comfort Temperature is already set. See Auto Schedule  
in Programming section.  
When the control is in heat pump configuration (HP1/  
HP2), the system switch configuration will have an  
additional mode available namely, Emer for Emergency  
Mode.  
6) Energy Management Recovery (EMR) (this step is  
skipped if configured as non-programmable).  
When set to "On" causes the thermostat to start heating  
or cooling early to make the building temperature reach  
the program setpoint at the time you specify.  
19) Select Cool Savings: With Cool Savingsenabled,  
the thermostat will make small adjustments to the  
setpoint temperature during periods of high demand to  
reduce AC 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  
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 eventu-  
ally cause the system to satisfy the thermostat to turn the  
system off and reduce the energy consumption. When  
the Cool Savingsfeature is active and making adjust-  
ments, the display will flash Cool Savings. The amount  
of the adjustments to the setpoint temperature is depen-  
dent on the Cool Savingsvalue 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 AC  
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. As demand lessens the adjustments  
to setpoint temperature are reversed until setpoint  
temperature returns to normal and Cool Savingsno  
longer flashes.  
Example: Let us say, the heating program is 65°F at  
night and 70° at 7 AM. If the building temperature is 65°F,  
the difference is 5°F. Allowing 5 minutes per °F rise, the  
thermostat setpoint will change to 70° at 6:35 AM.  
Cooling allows more time per °F, because it takes  
longer to reach temperature.  
7, 8 & 9) Cycle Rate Selection The factory default setting  
is fast cycle (FA Cr) in all modes (Heat, Cool, Emer). To  
slow cycling (SL, Cr), press touch keys  
or  
toggle  
between FA & SL. The cycle rates are as below different  
selections:  
Mode  
Heat  
Cool  
Fast rate  
0.6°F  
1.2°F  
Slow rate  
1.2°F  
1.7°F  
Emer  
1.2°F  
1.7°F  
10) Select Compressor Lockout (CL) 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 of the newer  
compressors have already got a time delay built in and  
do not require this feature to be activated in the thermo-  
stat. Your compressor manufacturer can tell you if  
this lockout feature is already present in their system.  
When the thermostat compressor time delay is activated,  
it will flash the set point for up to five minutes.

tion section).  
Factory settings are listed on Monday, Saturday and Sunday. If you are re-programming a 5+1+1 day schedule, pencil in your  
own times and temperatures directly below the factory times and temperatures.  
If you are re-programming a 7 day fill in all lines with the times and temperatures you want.  
Keep the following guidelines in mind when planning your program.  
In Heating, lower temperatures will save energy.  
In Cooling, higher temperatures will save energy.  
If you plan on using Auto Changeover, do not program the heating higher than the cooling.

Wired Remote Temperature Sensing  
One remote temperature sensor can be installed indoor or  
outdoor and connected to the thermostat by a maximum  
cable length of 100 meters (300 feet). Terminals +, S and -  
on the terminal block allow connection of the remote sensor.  
The thermostat must have 24 VAC Common connection to  
terminal C for the remote sensor to operate. The remote  
sensor can be enabled or disabled in the Installer/Configura-  
tion menu, item 25.  
Example: Local sensor temperature is 80° and the remote  
sensor is 70°.  
If weight is selected H4, the averaged temperature of 72° will  
be displayed.  
(1 x 80) + (4 x 70) / 5 = 72°  
If weight is selected A2, the average temperature of 73° will  
be displayed.  
(1 x 80) + (2 x 70) / 3 = 73.3°  
When remote sensor, Remote, is selected Off (factory  
default), no remote sensor is enabled. When remote sensor  
is selected On, the next step is to select the remote as  
indoor, Remote In, or outdoor, Remote Outdoor. If the  
remote is selected as Remote In, an additional step will be to  
select if the temperature shown on the display will be from  
the thermostat, LS On, or the remote sensor Ls Off.  
If weight is selected L1, the average temperature of 75° will  
be displayed.  
(1 x 80) + (1 x 70) / 2 = 75°  
The example shows that the weight selected would prioritize  
the overall averaged temperature between the two sensors.  
The high weight selection caused the remote sensor to have  
a higher influence in the calculated temperature average  
than the local sensor and the low weight selection caused  
the remote sensor to have less influence.  
In normal operation, when a remote sensor is enabled the  
time digits of the display will alternate between the time and  
the remote temperature for three seconds each. Above the  
remote temperature will be Remote, for indoor sensor or  
Outdoor Remote, for outdoor sensor. If the remote sensor is  
an indoor sensor and the local display has been disabled,  
the temperature displayed as the room temperature will be  
the remote sensor temperature.  
Dual Fuel Temperature Setpoint  
When the thermostat is configured for Heat Pump mode and  
an outside remote sensor is installed, the thermostat can  
monitor the outside temperature. When the outside tempera-  
ture falls below a user selectable temperature, the thermostat  
will switch to gas heat and shut down the compressor. This  
eliminates the need for a fossil fuel kit.  
Sensing Range:  
Outdoor temperature range is -40 to 140oF  
Indoor temperature range is 32 oF to 99oF  
The user selectable temperature is called the dual fuel  
temperature setpoint, dF and is set in the Installer/Configura-  
tion menu, item 26. The dual fuel temperature setpoint can  
be set to a temperature of 5 through 50. A selection of 5  
(default setting) disables this feature and menu selection of  
Cd will not be available.  
Weight of Remote Reading:  
The thermostat is designed to receive the temperature of the  
indoor remote sensor and average, or weight, it with the local  
sensor in the thermostat for each program period. The  
averaging will be active only when the local sensor and the  
indoor remote sensor are both functional and enabled in the  
Installer/Configuration menu.  
After the dual fuel temperature setpoint is set above 5 and  
is pressed, a delay, Cd, can be set for compressor shutdown  
after the auxiliary stage is energized. This delay can be set  
from 0 seconds to 99 seconds to minimize the time that the  
system may blow cooler air until the alternate source of heat  
comes on. Default setting for delay is 60. When setting the  
When the thermostat is in the Set Schedule mode, the weight  
of the indoor sensor will be shown in the current temperature  
digits of the display. The weight will show as A2 (average  
and default), H4 (high) or L1 (low). Pressing the  
and  
delay if the  
or  
keys are held depressed, the setpoint  
keys at the same time will change the weight for the program  
period. The weight of the local sensor is fixed.  
will increase or decrease at the rate of one degree every half  
second for the first three seconds and double the speed after  
three seconds.  
In normal operation of the thermostat, the current tempera-  
ture displayed will be the weighted average of the local  
sensor and the remote sensor using the formula (local  
sensor weight x local sensor temperature) + (remote sensor  
weight x remote sensor temperature) / (local sensor weight +  
remote sensor weight).

TROUBLESHOOTING  
Reset Operation  
Note: When thermostat is reset, installer configuration menu settings and programming will reset to factory settings.  
If a voltage spike or static discharge blanks out the display or causes erratic thermostat operation, you can reset the thermostat by removing  
the wires from terminals R and C (do not short them together) and removing batteries for 2 minutes. After resetting the thermostat, replace  
the wires and batteries. If the thermostat has been reset and still does not function correctly contact your heating/cooling service person or  
place of purchase.  
Note: Be sure to review the installer configuration menu settings.
