INSTALLATION

WARNING!
Thermostat installation and all components of the control system shall conform to Class II circuits per the NEC code.

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.

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 the 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 the appropriate wiring schematic.
  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®. If the home is going to be unoccupied for an extended period (over 3 months) and Emerson-1F95-1280-Blue-Series-Touchscreen-Thermostats-fig.2is displayed, the batteries should be replaced before leaving.
Power Stealing Switches
The Power Stealing Switches (Fig. 1) should be left in the “On” position for most systems. The information in the following table details the thermostat power method and switch options.

Thermostat Power Method Switch Position/Description
Battery Powered, no 24 Volt system power available . Switches “On”, thermostat runs on batteries .
Hardwired with Battery Back-up, for 24 Volt systems with common connection from transformer to “C” terminal

on thermostat .

 Switches “On”, thermostat runs on power directly from transformer with battery back- up .
*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 .

*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:

  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.
  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.

  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 compressor system, Gas or Electric backup; (Dual Fuel see menu item 27) (4 heat/2 cool)
    • SS1 – Single Stage System and 3 wire zone systems see wiring diagrams.
  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 thermostat switches the option to GAS.
  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 applications. If the heat pump requires the changeover valve to energize in HEAT, select “B”.
  4. Programs per week – This control can be configured for 7 independent day or 5/1/1 day programming or nonprogrammable modes. Default is 7-day mode. The display indicates “7 Days” as default. Other options “5 Days” or “0 Days” can be selected. 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.
  5. System Switch Configuration (MS2/SS1) – This thermostat is configured for Heat and Cool with Auto changeover default (Cool-Off-Heat-Auto). It 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 (HP1/
    HP2), the system switch configuration will have an
    additional mode available, Em 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: 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. Cycle Rate Selection – The factory default setting is fast cycle (FA Cr) in all modes (Heat, Cool, Emer). To change to slow cycling (SL, Cr), press touch keys Emerson-1F95-1280-Blue-Series-Touchscreen-Thermostats-fig.9 toggle between FA & SL. The cycle rates are below:
  8. Emerson-1F95-1280-Blue-Series-Touchscreen-Thermostats-fig.13
  9. Stage Cycle Completion (SC) – Selecting (SC On) will cause the thermostat to complete heating and/or cooling cycles on the highest stage engaged during the cycle. Thermostat will not reduce heating or cooling stages before the heating or cooling cycle is satisfied and all stages are turned off.
  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 a time delay built in and do not require this feature to be activated in the thermostat. 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.
  11. Select Continuous Backlight (dL) – In low lighting conditions, display backlight improves the display contrast. (See table 1)
  12. Select Temperature Display Adjustment 5 LO to 5 HI – This allows you to adjust the room temperature display by -5°F to +5°F in 1° steps. Your thermostat was accurately calibrated at the factory, however you have the option to change the display temperature value to match the previous thermostat, if you so prefer.
  13. Select °F or °C Readout – Changes the display readout to Celsius or Fahrenheit as required.
  14. select Audio Prompting (Beeper) On or Off – Factory default setting is b, On. If you wish to turn off the beeper select OFF.
  15. 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 is On.
  16. 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 or a “Comfort Temperature” is already set. See Auto Schedule in Programming section.
  17. Select Cool Savings™ – Cool Savings™ provides an energy saving temperature offset (from 1-6 degrees) under peak cooling load conditions (high outdoor temperatures). 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 adjustment 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.
    The principle of this energy saving feature takes advantage of the long air conditioning run times lowering the indoor humidity allowing a slightly higher temperature to feel comfortable. As the peak load subsides, this feature also takes advantage of the air conditioner’s increased capacity under more efficient conditions to gradually reduce the offset back to zero and return control to the selected setpoint temperature.
    If Cool Savings is selected off, no temperature offset will
    occur.
  18. 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 additional cooling from the system. If CO is set to OFF, there will be no delay in fan operation.
  19. Comfort Alert with Active Protection – (not available on earlier models) Turn this feature ON to enable active protection. This allows the thermostat to identify fault codes sent by the Comfort Alert module when compressor damage is possible and react to those codes by turning the compressor off. Fault codes from the Comfort Alert module will flash on the thermostat. (Refer to Comfort Alert Codes in Troubleshooting section.) If a Comfort Alert module is not connected, or to disable active protection, turn this feature OFF. If a Comfort Alert module is connected and this feature is turned OFF, the thermostat will still receive and flash the fault codes from the Comfort Alert module, but the active protection will not be enabled to protect the compressor.
  20. 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 to the left of your setpoint temperature when using this feature. “Temperature Limit” icon will flash if an attempt is made to adjust the temperature beyond the range selected.
  21. Cool Temperature Limit Range – This feature adjusts the lowest setpoint temperature for cool. The default setting is 45°F. It can be changed to a setting between 46°F and 82°F. “Temperature Limit” icon will be displayed to the left of your setpoint temperature when using this feature. “Temperature Limit” icon will flash if an attempt is made to adjust the temperature beyond the range selected.
  22. 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 or 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 Lockout 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.
      After the type of lockout is selected, pressEmerson-1F95-1280-Blue-Series-Touchscreen-Thermostats-fig.10 .
    • Keypad Lockout Combination Number Selection Display will read “000” “Keypad Lockout”.
      Skip this step and continue through the remainder of the configuration menu if you require an Air Filter Change out indicator or Humidifier Pad Change out indicator by pressing the key to advance.
      Return to this point when you are ready to start your selected lock-out and continue by:
      Pressing or 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 key will remain active for 10 seconds to allow setting Heat, Off, Cool or Auto.
      To unlock the keypad, press Menu, then press Installer Config. Display will show “000” and keypad lock. Enter the code used to lock the keypad and press .
  23. 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 temperature.
    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 temperature 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.
    The Fast Cool feature operates the cooling stages in the same manner as Fast Heat, On or Off when the temperature is lowered below the room setting.
  24. 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 enabled.
  25. 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.
  26. 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.
  27. Select Dual Fuel Feature (dF) – This feature is applicable only in heat pump modes (HP1, HP2). Enables (On) or disables (Off) dual fuel feature of thermostat.
  28. 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 temperature 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.
  29. Select Dual Fuel Setting – With DF selected On and no outdoor sensor, select the dF setting from 01-09. Factory 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 setting decreases the separation between stages. Decreasing the value increases stage separation. This adjustment 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.
    Note: This setting is not minutes or degrees. It is numeric setting that will influence the internal thermostat calculation for staging.
  30. 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.
  31. 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°.
    If indoor temperature drops below 45° because of a possible 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:
    • Press any key to retry the pump and erase the “Call for Service” icon.
    • When setpoint is achieved on Auxiliary, system will return to heat pump operation on next call for heat.
  32. 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.
  33. Select Economizer or Damper Operation – This option configures the thermostat A1 terminal for Commercial Occupied Damper systems or Economizer systems. Commercial 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.
    Select EC “Off” (Economizer Off) for Commercial Occupied 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 cooling. A1 is energized constantly during Day (occupied) time periods.
    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.
  34. Change UV Lamp – This feature allows the thermostat 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 optimum 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.
    When “Change UV Lamp” is displayed, you can clear it by pressing Clean Display.
  35. Select Change Filter Run Time – This feature allows 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 application, 200 hours of run time is approximately 30 days.

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 26.
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 -40oF to 140oF
  • Indoor temperature range is 32oF to 99 oF

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.
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.
In normal operation of the thermostat, the current temperature 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) + (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°
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 the Dual Fuel feature is selected on, the thermostat can monitor 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.
The user selectable temperature is called the dual fuel temperature 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.
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 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.

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.

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 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 .
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 ac-

ceptable cycle rate is not achieved, contact a local HVAC service person for additional suggestions .
Forgot Keypad Lockout Code Press the menu key (key will disappear) and hold in for 20 seconds . This unlocks the thermostat .
Blank display any or keypad not responding 1 . Voltage Spike or static discharge Use the Reset Operation shown above .
“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 .
Thermostat does not have Menu Screen Numbers 1 . Earlier version of thermostat To access the earlier version of instruction sheet (37-7292A) go to www.white-rodgers.com, enter 1F95-1280 in Model Number Search
