INSTALLATION

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

• Pull the thermostat body off the thermostat base. Forcing or prying on the thermostat will cause damage to the unit.
• Place base over hole in wall and mark mounting hole locations on wall using base as a template.
• 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.
• 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.
  Connect wires to terminal block on base using appropriate wiring schematic.
• Push excess wire into wall and plug hole with a fire resistant material (such as fiberglass insulation) to prevent drafts from affecting thermostat operation.
• 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 is displayed, the batteries should be replaced before leaving.

• This control can be configured for:
  • MS 2 – Multi-Stage System (no heat pump)
  • HP 1 – Heat Pump with one stage of the compressor
  • HP 2 – Heat Pump with two stage compressor or two-compressor system, Gas or Electric backup
  • SS 1 – Single Stage System 2)
• Select Cool Savings™ value – Selects the amount of adjustment for the Cool Savings™ feature in Cool mode with 1 (1°) being the least amount of adjustment and 6 (6°) being the most amount of adjustment. Default value is 3. Cool Savings is an optional energy saving feature that can reduce your cooling costs. It is based on the principal that lower indoor humidity makes a slightly higher temperature feel more comfortable. Cool Savings operates during periods of high demand which normally occur on the hottest summer days when a cooling system may run for hours to reach the thermostat setting. Long cooling run times also lower indoor humidity. Cool Savings, very slowly, adjusts the setpoint temperature to make the setpoint closer to the displayed room temperature, to a maximum of the number of degrees you select. Adjusting the setpoint temperature over a long cooling run time allows the system to reach your set temperature and turn off. The room temperature will actually be higher than the thermostat displays but the reduction in humidity will allow comfort at the slightly higher temperature. To turn this feature on in the Cool mode press Cool Savings. The display will show “Save” next to the setpoint temperature. When Cool Savings is making adjustments to the room temperature display “Save” will be flashing and the displayed room temperature may vary within the adjustment range you selected. 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.
• Energy Management Recovery: (this step is skipped if configured to be non-programmable). Energy Management Recovery (E) On enables 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: E On is selected and your heating is programmed 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 temperature.
• Cycle Rate Selection – The factory default setting for Heat and Cool modes, SS1, MS2, is medium cycle (ME). For Heat Pump, HP1, HP2, the default setting is medium (ME). For Emer (Aux) the default setting is fast cycle (FA). To change cycle rate, press the button. Cycle rate differentials for different settings are:
  • MODE Fast Medium Slow
    • FA ME SL
    • Heat (SS1, MS2) 0.4°F 0.6°F 1.7°F
    • Cool (SS1, MS2) 0.9°F 1.2°F 1.7°F
    • Heat Pump (HP1, HP2) 0.9°F 1.2°F 1.7°F
    • Emer (HP1, HP2) 0.6°F – 1.7°F
• Select Compressor Lockout CL OFF or ON – 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 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.
• System Mode Configuration – This thermostat is configured 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).
• 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.
• 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 display temperature to match your previous thermostat. The current or adjusted room temperature will be displayed.
• Select F° or C° Readout – Changes the display readout to Celsius or Fahrenheit as required.
• Select Audio Prompting (Beeper) On or Off – Factory default setting is on (b, On). To turn off the beeper, select OFF. Some models do not have a beeper. This setting has no effect on models without a beeper.
• 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 pressing the or buttons. A selection of 0 days for non-programmable will eliminate the need for EMR, and that step in the menu will be skipped
• 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.
• Select Automatic Schedule – 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” for both. When Heat AS On and Cool AS On are activated while in Heat or Cool mode, select desired setpoint temperature and press Auto Schedule. This value will be copied into all the morning, day and evening program periods. The night program periods will have a 6°F setback.
• Select Fast Second Stage ON or OFF – Heat pump or Multi-stage only, 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 the second stage will energize immediately. With FA OFF, second stage will not energize until the setpoint temperature 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.
• 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 Loc On. You can make it Loc Off if you desire by using or buttons. Then, only the indoor remote temperature reading will be used for control
• 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 or touch keys to select the feature OFF.
• 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 MENU to advance the menu. Three security settings are available in this menu item. Use the or buttons to select the lockout desired.

The remote sensor can be enabled or disabled in the Installer/Configuration menu, item 20. 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, Loc On, or the remote sensor Loc 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

Weighing of Remote Reading:
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 or buttons 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).

Dual Fuel Temperature Setpoint
When the thermostat is configured for Heat Pump mode and an outside remote sensor is installed and enabled, the thermostat can monitor the outside temperature to determine when to switch to auxiliary heat and shut down the compressor. This eliminates the need for a fossil fuel kit. The Compressor Off temperature (CO) set in the configuration menu, item 25, will determine when the auxiliary heat will start and the compressor will shut off. Default setting is 05° (feature disabled) and can be set for 06 to 50°. When the outside temperature falls to the selected temperature, the auxiliary heat system will begin. The auxiliary heat system can be fossil fuel (dF) or electric heat (EA). This is selected after CO is set greater than 05. If the auxiliary heat is fossil fuel, (df), a delay time for the compressor shut down (Cd) can be selected. Default for this delay is 60 seconds but can be set from 0 to 99 seconds. If EA is selected, there is no selection for Cd because the compressor will shut down immediately.

TROUBLESHOOTING

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.     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 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 button (button will disappear) and hold in for 20 seconds. This unlocks the thermostat.
