INSTALLATION  
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.  
WARNING  
!
Thermostat installation and all components of the  
control system shall conform to Class II circuits per  
the NEC code.  
Battery Location  
Remove Old Thermostat  
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).  
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.

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.

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  
37-6740A).

Energy Management Recovery (E) On causes 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: If E On is selected 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 set-  
point will change to 70° at 6:35 AM. Cooling allows  
more time per degree, because it takes longer to reach  
temperature.

10) 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 compres-  
sors 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.

second stage will energize immediately. With FA OFF,  
the  
second stage will not energize until the setpoint tempera-  
ture is 1°F or more above actual temperature for more  
than ten minutes. The Fast Cool feature (FA Cool)  
provides the same controls when the setpoint tempera-  
ture is lowered.  
12) 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 cali-  
brated at the factory, but you have the option to change  
the display temperature to match your previous thermo-

Planning Your Program – Important  
The Heating and Cooling Program schedules below allow you to pencil in your own program times and temperatures.  
The 1F95-1271 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 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.

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.  
To reset the programming, clock and configuration settings, press  
should go blank and then all segments will be displayed momentarily.  
and  
and the SYSTEM button simultaneously. The thermostat  
Possible Cause  
Corrective Action  
Symptom  
1. Blown fuse or tripped circuit breaker.  
2. Furnace power switch to OFF.  
Replace fuse or reset breaker.  
Turn switch to ON.  
No Heat/No Cool/No Fan  
(common problems)  
3. Furnace blower compartment door or  
panel loose or not properly installed.  
Replace door panel in proper position to engage safety  
interlock or door switch.  
4. Loose connection to thermostat or system. Tighten connections.  
1. Pilot light not lit.  
Re-light pilot.  
No Heat  
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.  
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.  
No Cool  
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  
described 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.  
Heat, Cool or Fan  
Runs Constantly  
2. Possible short in thermostat.  
3. Possible short in heat/cool/fan system.  
4. FAN Switch set to Fan ON.  
1. Thermostat thermometer setting  
requires adjustment.  
The thermometer can be adjusted +/- 4 degrees. See  
Temperature Display Adjustment in the Configuration  
Menu section.

1. The location of the thermostat and/or  
the size of the Heating System may  
be influencing the cycle rate.  
Digital thermostats provide precise control and cycle faster  
than older mechanical models. The system turns on and  
off more frequently but runs for a shorter time so there is  
no increase in energy use. If you would like an increased  
cycle time, choose SL for slow cycle in the Configuration  
menu, step 6 (heat) or 7 (cool). If an acceptable cycle rate  
is not achieved, contact a local HVAC service person for  
additional suggestions.  
Furnace (Air Conditioner)  
Cycles Too Fast or Too Slow  
(narrow or wide  
temperature swing)  
Press the menu button (button will disappear) and hold in  
for 20 seconds. This unlocks the thermostat.
