INSTALLATION  
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  
runs on batteries.  
Hardwired with Battery  
Back-up, for 24 Volt systems runs on power directly from  
Switches "On", thermostat  
with common connection from transformer with battery back-  
transformer to "C" terminal  
on thermostat.  
up.  
Remove Old Thermostat  
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.  
*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:  
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 snugly,  
use plastic screw anchors to secure the base.  
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.  
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.  
3. The furnace may not turn off when the call for heat ends.  
4. The air conditioner may not turn off when the call for cool  
ends.  
5. Connect wires to terminal block on base using appropriate  
wiring schematic.  
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.  
6. Push excess wire into wall and plug hole with a fire resis-  
tant 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.  
Figure 1 – Thermostat Base Multi-Stage 1F95-1280  
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.

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  
period (over 3 months) and  
is displayed, the batteries  
should be replaced before leaving.

Example: 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 set-  
point will change to 70° at 6:35 AM. Cooling allows more  
time per °F, because it takes longer to reach temperature.  
1. This control can be configured for:  
MS2 – Multi-Stage System - No Heat Pump (2 heat/2  
cool)  
HP1 – Heat Pump with one stage of compressor (2  
heat/1 cool)  
HP2 – Heat Pump with two stage compressor or two

10. Select Compressor Lockout (CL) – Selecting (CL On)  
will cause the thermostat to wait 5 minutes between cool-  
ing cycles. This is intended to help protect the compressor  
from short cycling. Some of the newer compressors have  
a time delay built in and do not require this feature to be  
activated in the thermostat.Your compressor manufactur-  
er 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.  
3. O/B Terminal selection – Selects the operation of the  
reversing valve (when item 1 is set to HP1 or HP2 only).  
When set to "O" the changeover valve will be energized  
in COOL to accommodate the majority of heat applica-  
tions. If the heat pump requires the changeover valve to  
energize in HEAT, select "B".  
4. Programs per week – This control can be configured for

19 & 20. Select Cool Savings™ – Cool Savings™ provides  
an energy saving temperature offset (from 1-6 degrees)  
under peak cooling load conditions (high outdoor tem-  
peratures). If selected on, Cool Savings™ becomes active  
when the air-conditioner runs for periods of longer than 20  
minutes. When active, Cool Savings™ gradually offsets the  
indoor temperature display downward. The first 1° of adjust-  
ment will take one hour of continuous air conditioner run  
time with subsequent 1° adjustments occurring with each  
additional half hour of run time (Example: For a 2° offset,  
the air conditioner would need to run continuously for 1 ½  
hours). The offset is limited to the number of degrees you  
select from 1 up to 6. When an offset starts or is active,  
“Cool Savings” will flash on the display.  
"Keypad Lockout and P" = Partial Lockout. Partial Lock-

21. Compressor Optimization – (Not available on earlier  
models) CO provides a delay in circulator fan operation  
after the compressor tuns on or off. With CO selected ON,  
when the compressor turns on (for a call for heat in heat  
pump or a call for cool) the fan will be delayed for five  
seconds before turning on to allow the air to be heated or  
cooled. After the compressor turns off for call for cool, the  
fan will continue to run for 20 seconds to capture addi-  
tional cooling from the system. If CO is set to OFF, there  
will be no delay in fan operation.  
22. Heat Temperature Limit Range – This feature adjusts  
the highest setpoint temperature for heat. The default  
setting is 99°F. It can be changed to a setting between  
62°F and 98°F. Temperature Limit" icon will be displayed

26 & 27. Select Fast Second Stage, ON or OFF – Selecting  
FA ON forces additional heat stages to come on quickly  
when  
is used to raise the temperature a few degrees  
above the room. Select this setting if you want the heat to  
increase quickly when you manually raise the tempera-  
ture.  
Selecting FA OFF allows the thermostat to calculate an  
optimal time to bring on additional stages of heat. When  
the  
is used to raise the setting above the room tem-  
perature additional heat stages may come on very quickly  
or very slowly (up to 30 minutes later) depending on  
recent system performance. Select this setting if you do  
not require the additional heat stages to come on quickly  
when you manually raise the setting and want to allow the  
thermostat to stage based on recent system performance.

INSTALLER/CONFIGURATION MENU  
The Fast Cool feature operates the cooling stages in the  
same manner as Fast Heat, On or Off when the tempera-  
ture is lowered below the room setting.  
If indoor temperature drops below 45° because of a pos-  
sible heat pump malfunction, the thermostat will turn off  
the pump and switch to Auxiliary heat. "Call for Service"  
will display on screen.  
There are two ways the thermostat will return to normal  
heat pump operation:  
28. Select Remote Temperature Sensor Enabled – ON  
enables a remote sensor connected to thermostat and  
displays the sensor temperature in the clock digits. OFF  
(default) indicates no remote sensor connected or en-  
abled.  
Press any key to retry the pump and erase the "Call  
for Service" icon.  
29. Selects Remote Sensor as Indoor or Outdoor – If 28  
is enabled, select the remote to be Remote In (Indoor,  
F145-1328) or Outdoor Remote (Outdoor, F145-1378).  
Default is Remote In.  
When setpoint is achieved on Auxiliary, system will  
return to heat pump operation on next call for heat.  
36. Select Pre-Occupancy Purge (PP) – A selection of -O-  
opens the damper at the Day (occupied) program period.  
A selection of 1, 2 or 3 opens the damper early, 1, 2 or 3  
hours before the Day (occupied) time in the program. This  
allows 1, 2 or 3 hours of fresh air circulation before people  
arrive.  
30. Select Local Sensor Disable – If 29 is selected Indoor,  
the thermostat Local Sensor can be disabled so the  
displayed temperature will be from the Remote Sensor.  
Default is On LS. To disable the Local Sensor, change  
selection to OFF LS.  
37. Select Economizer or Damper Operation – This option  
configures the thermostat A1 terminal for Commercial  
Occupied Damper systems or Economizer systems. Com-  
mercial Occupied Damper systems open a damper during  
all Day (occupied) program time periods. Economizer  
systems use the A1 terminal to open an economizer and  
use outside air as the first cooling stage.  
31. Select Dual Fuel Feature (dF) – This feature is appli-  
cable only in heat pump modes (HP1, HP2). Enables (On)  
or disables (Off) dual fuel feature of thermostat.  
32. Select Dual Fuel Temperature – With dF selected On  
and outdoor remote sensor available, select the outdoor  
temperature the thermostat will use to determine when to  
switch to gas heat and shut down the compressor. When  
the outdoor temperature falls below the selected tem-  
perature the gas heat will begin. Default is 35°, but can be  
set in the range of -5 to 50°. A lower setting will delay the  
start of gas heat allowing cooler temperature in the home.  
Select EC "Off" (Economizer Off) for Commercial Oc-  
cupied Damper systems that require the A1 terminal to be  
energized constantly during Day (occupied) program time  
periods. With EC Off, the cooling terminals and stages  
operate as follows:Y = Stage 1 cooling, Y2 = Stage 2 cool-  
ing. A1 is energized constantly during Day (occupied) time  
periods.  
33. Select Dual Fuel Setting – With DF selected On and no  
outdoor sensor, select the dF setting from 01-09. Fac-  
tory default is 05. The dF setting influences when second  
stage comes on. The factory default creates a separation  
of approximately 1oF between stages. Increasing the set-  
ting decreases the separation between stages. Decreas-  
ing the value increases stage separation. This adjust-  
ment allows a small change in the operation of your heat  
pump system versus your auxiliary system relative to the  
thermostat adjustment. The higher the number the sooner  
the auxiliary stage energizes for better comfort. The lower  
the number the longer period of time before auxiliary is  
energized for more economy.  
Select EC "On" (Economizer On) for Economizer systems  
that use outside air for the first stage of cooling. With EC  
On selected, the cooling terminals and stages operate  
as follows: A1 = Stage 1 cooling, Y = Stage 2 cooling, Y2  
= Stage 3 cooling. EC "On" also runs the first stage of  
cooling (economizer) longer than a standard (compressor)  
cooling stage because economizers are more efficient  
with a longer run time.  
41 & 42. Change UV Lamp – This feature allows the thermo-  
stat to display the words "Change UV Lamp" (Call for  
Service of UV bulb) after a set time of UV bulb operation.  
This is a reminder to maintain your UV system at opti-  
mum level of operation. When enabled, the factory set  
interval for "Change UV Lamp" to be displayed is 350  
days of UV bulb operation and can be adjusted in 25 day  
increments. This should be adjusted with respect to the  
bulb’s recommended maintenance schedule.  
Note: This setting is not minutes or degrees. It is numeric  
setting that will influence the internal thermostat calcula-  
tion for staging.  
34. Select Compressor Delay (Cd) – Applicable only in  
heat pump modes (HP1, HP2). After the auxiliary heat is  
turned on, the compressor(s) shut down is delayed for the  
time selected (in seconds). This delay is factory set to 60,  
but can be set in the range of 0 to 99.  
When "Change UV Lamp" is displayed, you can clear it  
by pressing Clean Display.  
43 & 44. Select Change Filter Run Time – This feature al-  
lows thermostat to display "Change Filter" after a set  
time of blower operation. This is a reminder to change  
or clean your air filter. This time can be set from 25 to  
1975 hours in 25 hour increments. A selection of OFF will  
cancel this feature. When "Change Filter" is displayed,  
you can clear it by pressing Clean Display. In a typical ap-  
plication, 200 hours of run time is approximately 30 days.  
35. Select Auxiliary Off (AO) – Applicable only In heat pump  
modes (HP1, HP2) with outdoor sensor available. Select  
the temperature that will inhibit the auxiliary heating  
stage. As long as the outdoor temperature is above the  
selected temperature, the auxiliary heat will not turn on.  
The default setting is 60°, but can be set in the range of  
-5 ° to 79°.

PlanningYour Program – Important  
The Heating and Cooling Program schedules below allow you to pencil in your own program times and temperatures.  
The 1F95-1280 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  
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 26.  
(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.  
(1 x 80) + (1 x 70) / 2 = 75°  
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,  
LS On, or the remote sensor LS Off.  
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  
the Dual Fuel feature is selected on, the thermostat can moni-  
tor the outside temperature using remote sensor F145-1378  
or use software logic to determine when to switch to gas heat  
and shut down the compressor. This eliminates the need for a  
fossil fuel kit.  
Sensing Range:  
Outdoor temperature range is -40oF to 140oF  
Indoor temperature range is 32oF to 99oF  
The user selectable temperature is called the dual fuel tem-  
perature setpoint, dF and is set in the Installer/Configuration  
menu, items 32 or 33. With outdoor remote sensor installed  
and enabled, the dual fuel temperature setpoint (menu item 33)  
can be set to a temperature of 5° through 50°. When outdoor  
remote sensor is not installed, a software logic based dual fuel  
number (menu item 32) from 01 to 09 can be selected.  
Averaging or Weighting Remote Sensors  
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.  
After the dual fuel temperature setpoint is set 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  
keys at  
the same time will change the weight for the program period.  
The weight of the thermostat sensor is fixed.  
delay, if the  
or  
keys are held depressed, the setpoint  
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 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  
and SYSTEM keys 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.  
3. Furnace blower compartment door or  
panel loose or not properly installed.  
4. Loose connection to thermostat or system.  
Replace fuse or reset breaker.  
Turn switch to ON.  
Replace door panel in proper position to engage safety  
interlock or door switch.  
Tighten connections.  
No Heat  
1. Pilot light not lit.  
2. Furnace Lock-Out Condition. Heat  
may also be intermittent.  
Re-light pilot.  
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.  
Heat, Cool or Fan  
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.  
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.

Cycles Too Fast or Too Slow  
(narrow or wide  
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 7 (heat) or 8 (cool). If an ac-  
ceptable cycle rate is not achieved, contact a local HVAC  
service person for additional suggestions.

"Call for Service" on display  
Power applied to thermostat "L" terminal  
Indicates the heat pump system is sending a signal (volt-  
age) to the thermostat terminal marked "L". It does not  
indicate a malfunction in the thermostat. The manufac-  
turer of the Heat Pump system can determine the likely  
cause of Call for Service on the thermostat by identifying  
the component in the system sending power to the "L"  
terminal.
