INSTALLATION

WARNING
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.

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 snugly, 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).
6. Push excess wire into wall and plug hole with a fire resistant 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.

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 premium brand “AA” alkaline battery such as Duracell® or Energizer®.

WIRING CONNECTIONS

Refer to equipment manufacturers’ instructions for specific system wiring information. After wiring, see CONFIGURATION section for proper thermostat configuration.

1. This control can be configured for:
   MS2 – Multi-Stage System (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 compressor system, Gas or Electric backup; (Dual Fuel see menu item 26) (3 heat/2 cool)
   SS1 – Single Stage System (3 wire zone see wiring diagram 37-6808A)

2. 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. Note: Resetting the thermo- stat switches the  option to ELE.

3. Programs per week — This control can be configured for 7 independent day or 5/1/1 day programming or non- programmable modes. Default is 7-day mode. The display indicates “7 Days” as default. Other options “5 Days” or “0  Days” can be selected by pressing touch keys, . If “0 Days” is selected for non-programmable mode, the step for EMR will be skipped, as this feature will not be available in this mode.

4. Program Steps per day — This control can be configured for 4 or 2 program steps per day. Default is “4 PS” and can be toggled between 4 PS and 2 PS by pressing the  touch keys.

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). When the control is in heat pump configuration (HP 1/ 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.
   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  toggle between FA & SL. The cycle rates are as below different selections:
   Mode Fast rate Slow rate
   Heat 0.6°F 1.2°F
   Cool 1.2°F 1.7°F
   Emer 1.2°F 1.7°F

8. 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.

9. Select Continuous Backlight — In low lighting conditions, display backlight improves the display contrast. When C terminal is connected, selecting dL On will turn the backlight on continuously. Selecting dL Off will turn the  backlight on momentarily after any key is pressed. When C terminal is not powered (battery only), dL On enables the momentary backlight whenever a key is pressed.

10. Select Backlight Intensity — This thermostat has the ability to provide two selectable intensities of the backlight: HI and LO. Using touch keys you can toggle the selection between HI and LO.

11. Select Temperature Display Adjustment 4 LO to 4 HI This allows you to adjust the room temperature display by an amount in the range of -4°F to +4°F in 1° steps by using the touch keys. Your thermostat was accurately  calibrated at the factory, however you have the option to change the display temperature value to match your previous thermostat, if you so prefer.

12. Select °F or °C Readout — Select the desired temperature unit by pressing . Factory default is °F.

13. Select Audio Prompting (Beeper) On or Off — Factory default setting is on (b, On). If you wish to turn off the beeper  select OFF.

14. Select Daylight Saving Time Calculation — This feature will allow the thermostat to calculate the DST automatically and apply it to the Real Time Clock display. Default On. Use touch keys to select the  feature, OFF.

15. & 18) Select Automatic Schedule — This feature allows programming a “Comfort Temperature” into 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 oar “Comfort Temperature is already set. See Auto Schedule in Programming section.

16. Select Cool Savings™: With Cool Savings™ enabled, 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 eventually cause the system to satisfy the thermostat to turn the system off and reduce the energy consumption. When the Cool Savings™ feature  is active and making adjust- ments, the display will flash “Cool Savings”. 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 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 Savings” no longer flashes.

17. Heat Temperature Limit Range — This feature adjusts the highest setpoint temperature for heat. The default setting is 99°F. It can be changed between 62°F and 98°F by pressing the key. The “temperature limit” icon will be displayed to the left of your setpoint temperature when using this feature. The “temperature limit” icon will flash if an attempt is made to adjust the temperature beyond the range selected.

18. Cool Temperature Limit Range — This feature adjusts the lowest setpoint temperature for cool. The default setting is 45°F It can be changed between 46°F and 82°F by pressing the key. The “temperature limit” icon will be displayed to the left of your setpoint temperature when using this feature. The “temperature limit” icon will flash if an attempt is made to adjust the temperature beyond the range selected.

19. Keypad Lockout — This step allows you to select the type of lockout or limited range security required. If no lockout or limited range security is required, press to advance the menu. Three security settings are available in this menu item. Use the keys to select the lockout desired.
    Lockout selections are: “Keypad Lockout and L” = Total Lockout. Total Lockout locks all keys. “Keypad Lockout and P ” = Partial Lockout. Partial Lock- out allows only the or keys to operate within your set temperature limits. “Temperature Limit/Keypad Lockout” prevents changing the temperature limits in the Configuration Menu. Keypad Lockout Combination Number Selection Display will read “OFF” “Keypad Lockout”. Skip this step and continue through the configuration menu items 19 thru 22 if you require an Air Filter Change out indicator or Humidifier Pad Change out indicator by pressing the button to advance. Return to this point when you are ready to start your selected lock- out and continue by: Pressing keys to select ON. Press A. Display will read “000”. Pressing keys to select your keypad lockout combination number. Note: “000” is not a valid combination choice.
    Record the number you select for future use.
    Press to exit the menu. The security feature you select will start in 10 seconds. The system button will remain active for 10 seconds to allow setting Heat, Off, Cool or Auto.

20. & 24) Select Fast Second Stage ON or OFF – In the run mode, with the fast Heat feature enabled (FA Heat On), if the Heat setpoint temperature is manually raised by 3°F (2°C) or more above the actual temperature using A\ the second stage will energize immediately. With FA OFF, 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 temperature is lowered.

21. Select Remote Temperature Sensor — This control allows one wired remote temperature sensor (indoor, F145-1328, or outdoor, F145-1378) be connected to it and indicates the measured temperature in clock digits. This menu  enables you to select the remote sensor and also configure it as indoor or outdoor temperature sensor. Factory default is off. Select Remote On and Remote in (for indoor) or Outdoor Remote. Local Temperature Sensor disable —  This is applicable only when indoor remote temperature sensor is enabled. Factory default is On LS. You can make it Off LS if you desire by using touch keys. Then, only the indoor remote temperature reading will be used  for control.

22. Select Dual Fuel Feature and Setpoint — This feature inapplicable only in heat pump modes. An outside remote sensor must also be installed. When the outside tem- perature falls below the selected setpoint temperature, dF, the  thermostat will switch to gas heat and shut down the compressor. Use the keys to select the desired setpoint temperature in the range of 5 to 50. Factory default is 5, which disables this feature. See Dual Fuel Temperature  and Setpoint in Programming section. Select Compressor Delay — When dF is enabled, the shut down of the compressor(s) is delayed for a time period after the auxiliary stage is energized. This delay, Cd, is factory set at 60, but can  be set in the range of 0 to 99.

23. Select Change Filter Run Time — The thermostat will 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 application, 200 hours of run time is approximately 30 days.

period. The display will show FAN On Prog.
In the Run mode, pressing the FAN key will change the fan from Auto (default setting) to On (fan running continuously) or Prog. When FAN Prog is displayed, the fan will run when the system cycles. If the system does not cycle for more  than 60 minutes, the thermostat will turn the fan on for 10 minutes and off for 20 minutes to improve indoor air quality. If the display shows FAN On Prog to indicate the program period has the fan programmed to run, FAN Prog will  override the programmed setting until Run Schedule is pressed or the next schedule period begins.

Planning Your Program — Important
The Heating and Cooling Program schedules below allow you to pencil in your own program times and temperatures.
The 1F95-1277 comes configured for 7 day programming and can also be configured for 5+1+1 programming (see configuration 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/Configuration menu, item 25.
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.
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 -40 to 140°F
Indoor temperature range is 32°F to 99°F
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.
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 local sensor is fixed.
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.
(1 x 80) + (4x 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°
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.
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 temperature 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.
The user selectable temperature is called the dual fuel temperature setpoint, dF and is set in the Installer/Configuration 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.
After the dual fuel temperature setpoint is set above 5 and AA 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 delay if the 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.

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 and and the SYSTEM button simultaneously. The thermostat should go blank and then all segments will be displayed momentarily.

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.
3.  Heating system requires service or thermostat requires replacement.| 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.
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.
2.  Possible short in thermostat.
3.  Possible short in heat/cool/fan system.
4.  FAN Switch set to Fan ON.| 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.
Thermostat Setting & Thermostat Thermometer Disagree| 1.  Thermostat thermometer setting requires adjustment.| The thermometer can be adjusted +/- 4 degrees. See Temperature Display Adjustment in the Configuration Menu section.
Furnace (Air Conditioner) Cycles Too Fast or Too Slow (narrow or wide

temperature swing)

| 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 acceptable cycle rate is not achieved, contact a local HVAC service person for additional suggestions.
Forgot Keypad Lockout Code| | Press the menu button (button will disappear) and hold in for 20 seconds. This unlocks the thermostat.
