Thermostat Power Method  
Switch Position/Description  
WARNING  
Thermostat installation and all components of the  
control system shall conform to Class II circuits per  
the NEC code.  
!
Battery Powered, no 24  
Volt system power available.  
Switches "On", thermostat

up.  
Before removing wires from old thermostat, mark wires for  
terminal identification so the proper connections will be made  
to the new thermostat.  
*Battery Powered with  
Power Stealing Assist,  
for 24 Volt systems with no  
common connection from  
transformer to "C" terminal on  
thermostat.  
Switches "On", thermostat  
runs on batteries and  
supplemental power drawn  
through the heat or cool circuit.  
Installing New Thermostat  
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.  
*Power Stealing Assist is very reliable to increase battery life,  
but on a small number of heating or cooling systems with high  
impedance electronic modules you may observe one of the  
following conditions:  
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.  
1. The furnace draft inducer motor may run with no call for  
heat.  
2. The furnace fan may turn on with no call for heat or may  
not turn off.  
3. The furnace may not turn off when the call for heat ends.  
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.  
4. The air conditioner may not turn off when the call for cool  
ends.  
If the Power Stealing Assist method is not compatible with  
your system, place the Power Stealing Switches to "Off". This  
cancels Power Stealing Assist, operates the thermostat on  
batteries and corrects the condition.  
Battery Location  
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.  
Figure 1 – Thermostat Base Multi-Stage 1F97-0671  
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 premi-  
um brand "AA" alkaline battery such as Duracell® or Ener-  
gizer®. If the home is going to be unoccupied for an extended

1) GAS or Electric (ELE) fan operation. If the heating system  
requires the thermostat to energize the fan, select ELE.  
Select GAS if the heating system energizes the fan on a  
call for heat.  
6) Select Compressor Lockout CL OFF or ON – Selecting  
CL ON will cause the thermostat to wait 5 minutes be-  
tween 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.  
2) Select Cool Savings™ – Cool Savings allows you to  
select a temperature offset (from 1-6 degrees). When  
the compressor runs for long periods, the thermostat will  
internally slowly/gradually adjust the room temperature  
display lower, subtracting a maximum of the number of  
degrees you select.  
7) System Mode Configuration – This thermostat is config-  
ured for Heat and Cool (SYSTEM switch with Cool Off  
Heat) default. It can also be configured for Heat and Cool  
with Auto changeover (Heat, Auto, Cool, Off), Heat only  
with fan (Off Heat), Heat only without fan, Auto only  
(Auto Off), and Cool only (Cool Off).  
This energy saving feature is based on the principal that  
long compressor run times lower indoor humidity and  
make slightly higher temperature feel comfortable. Cool  
Savings operates only when the compressor runs 20  
minutes or longer, normally on the hottest summer days.  
When Cool Savings is operating the thermostat will flash  
"Cool Savings" to indicate it is slowly adjusting the dis-  
play temperature lower.  
8) Select Backlight Display – The display backlight improves  
display contrast in low lighting conditions. When the "C"  
terminal is powered, selecting backlight CdL ON will keep  
the light on continuously. Select backlight OFF will turn the  
light on momentarily after any button is pressed. When the  
"C" terminal is not powered, the light will be on momentarily  
after any button is pressed no matter whether the backlight  
is selected ON or OFF.  
To turn this feature on in the Cool mode press Cool  
Savings. The display will show “Save” next to the set-  
point temperature. When Cool Savings is making adjust-  
ments to the room temperature display “Save” will be  
flashing and the displayed room temperature may vary  
within the adjustment range you selected.  
9) 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 dis-  
play temperature to match your previous thermostat. The  
current or adjusted room temperature will be displayed.  
If "Save" is not displayed and this feature is OFF, no  
change will occur when the cooling system is continuously  
running during periods of high demand.  
3) Energy Management Recovery: (this step is skipped if  
configured to be non-programmable).  
10)Select F° or C° Readout – Changes the display readout  
Energy Management Recovery (E) On enables the ther-  
mostat 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.

beeper select OFF.  
12)Program Options: Selects configuration for 7 day (7) or  
5/1/1 day (3) programming or non-programming (0) mode.  
The default setting is 7, indicating 7 day programming.  
The programs per week can be changed to 3 or 0 by  
Example: E On is selected and your heating is 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 set tempera-  
ture.

that step in the menu will be skipped.  
13)Program Steps per day – This control can be configured  
for 4 or 2 program steps per day. Default is "2 PS" and  
can be toggled between 4 PS and 2 PS.  
4 & 5) Cycle Rate Selection – The factory default setting for  
Heat and Cool modes is medium cycle (ME). To change  
cycle rate, press the  
or  
button.  
14 & 15) Select Automatic Schedule – 1F97 only, with just  
one touch of the Auto Schedule key this feature allows  
you to program a desired comfort temperature into all the  
program periods along with a 6° set back for night periods  
of both Heat and Cool programs. Factory default is "On"

PlanningYour Program – Important  
The Heating and Cooling Program schedules below allow you to pencil in your own program times and temperatures.  
The 1F97-0671 comes configured for 7 day programming and can also be configured for 5+1+1 programming (see configura-  
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 schedule, 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 temperature higher than the cooling temperature.

PROGRAMMING  
Weighing of Remote Reading:  
Entering Fan Program  
The thermostat will weight or average the temperature of the  
indoor remote sensor 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.  
The fan can be programmed to turn on at the beginning of a  
period and remain on through the whole period. In RunSched  
mode when the FAN switch indicates Prog Fan On the fan is  
programmed to be on for the period.  
1) Press System button to select either Heat or Cool.  
2) Press Menu button and then press Fan button to the right  
of the display.  
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  
3) The top of the display will show the day(s) being pro-  
grammed. The first period to be programmed will appear.  
4) Press the Fan button to change from Auto to Prog.  
5) Press the Fan button to the right of the display to change  
to the next period.  
6) Repeat steps 4 and 5 to program the fan for all periods of  
the day.  
7) Press Fan to advance to the next day of the week and  
repeat steps 4 through 7 to program the fan for all days of  
the week.  
default), H4 (high) or L1 (low). Pressing the  
tons at the same time will change the weight for the program  
period. The weight of the thermostat sensor is fixed.  
or  
but-  
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).  
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.  
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 sen-  
sor can be enabled or disabled in the Installer/Configuration  
menu, item 16.  
(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°  
If weight is selected L1, the average temperature of 75° will  
be displayed.  
When remote sensor, Remote, is selected Off (factory de-  
fault), 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 se-  
lected as Remote In, an additional step will be to select if the  
temperature shown on the display will be from the thermostat,  
Loc On, or the remote sensor Loc Off.  
(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.  
Sensing Range:  
Outdoor temperature range is -40oF to 140oF  
Indoor temperature range is 32oF to 99oF

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 thermo-  
stat 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.  
To reset the programming, clock and configuration settings, press the  
,
and SYSTEM button simultaneously. The  
thermostat should go blank and then all segments will be displayed momentarily.  
Symptom  
Possible Cause  
Corrective Action  
No Heat/No Cool/No Fan  
(common problems)  
1. Blown fuse or tripped circuit breaker.  
2. Furnace power switch to OFF.  
Replace fuse or reset breaker.  
Turn switch to ON.  
3. Furnace blower compartment door or  
panel loose or not properly installed.  
4. Loose connection to thermostat or system.  
Replace door panel in proper position to engage safety  
interlock or door switch.  
Tighten connections.  
No Heat  
1. Pilot light not lit.  
Re-light pilot.  
2. Furnace Lock-Out Condition. Heat  
may also be intermittent.  
Many furnaces have safety devices that shut down when  
a lock-out condition occurs. If the heat works intermittently  
contact the furnace manufacturer or local HVAC service  
person for assistance.  
3. Heating system requires service or  
thermostat requires replacement.  
Diagnostic: Set SYSTEM Switch to HEAT and raise the  
setpoint above room temperature. Within a few seconds  
the thermostat should make a soft click sound. This sound  
usually indicates the thermostat is operating properly. If  
the thermostat does not click, try the reset operation listed  
above. If the thermostat does not click after being reset  
contact your heating and cooling service person or place  
of purchase for a replacement. If the thermostat clicks,  
contact the furnace manufacturer or a HVAC service  
person to verify the heating is operating correctly.  
No Cool  
1. Cooling system requires service or  
thermostat requires replacement.  
Same as diagnostic for No Heat condition except set the  
thermostat to COOL and lower the setpoint below the  
room temperature. There may be up to a five minute delay  
before the thermostat clicks in Cooling.

Runs Constantly  
1. Possible short in wiring.  
Check each wire connection to verify they are not shorted  
or touching together. No bare wire should stick out from  
under terminal block. Try resetting the thermostat as de-  
scribed above. If the condition persists the manufacturer  
of your system or service person can instruct you on how  
to test the Heat/Cool system for correct operation. If the  
system operates correctly, replace the thermostat.
