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.

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.

WIRING DIAGRAMS

Single Stage and Multi-Stage Connections
Refer to equipment manufacturers’ instructions for specific system wiring information. This thermostat is designed to operate a single-transformer or two-transformer system. You can configure the thermostat for use with the following fossil fuel systems

Heat Pump Connections 
If you do not have a heat pump system, refer to figures 3 & 4. Refer to equipment manufacturers’ instructions for specific system wiring information. You can configure the thermostat for use with the following heat pump systems.

HM	DHM
Humidification Terminal, Energizes on call for heat if Humidity setpoint is above room humidity. Can also be used to provide humidification independent of a call for heat and/or in cooling mode if Automatic Humidification is selected in Configuration Menu item #42	De-energizes on call for Dehumidification to lower the fan speed. The DHM terminal is only used on systems with a compatible dehumidification feature that have the required terminal connection on the contol module or have a relay installed to lower the fan speed

Dehumidification wiring without an electronically controlled variable speed blower system for single stage compressor system only

If you have a single stage compressor system see the diagram below. A relay (customer provided) should be installed as shown in Fig 7 to switch the fan speed to the next lower speed on a call for dehumidification from the thermostat. The reduction in air flow allows the coil to remove more humidity from the air. The relay should be rated for blower motor load. Since this configuration reduces the air flow in cooling, the anti-freeze-up control (White-Rodgers CAFC) or equivalent is recommended. The CAFC prevents the air conditioning coil from freezing due to low air flow, dirty filters, low refrigerant pressure, etc. The CAFC snaps onto the suction line close to the evaporator coil as possible and breaks the compressor circuit when the suction line drops below 38°F and re-make the circuit at 46°F.

• 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 screen reference number 33) (4 heat/2 cool)
• SS1 – Single Stage System (3 wire zone see wiring diagrams.
• 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.
• 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”.
• 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.
• Program Steps per day – Not available if configured for non-programmable. 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.
• 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, Em for Emergency.
• 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.
• Cycle Rate Selection – The factory default setting is fast cycle (FA Cr) in all modes (Heat, Cool, Em). To change to slow cycling (SL, Cr), press touch keys or toggle between FA & SL. The cycle rates are below:
• Mode Med Slow Heat 0.6°F 1.5°F Cool 1.2°F 1.7°F Heat Pump 1.2°F 1.7°F Emer Heat 0.6°F 1.7°F
• 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. The thermostat will not reduce heating or cooling stages before the heating or cooling cycle is satisfied and all stages are turned off.
• 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.
• Select Continuous Display Lighting (dL) – In low lighting conditions, display backlight improves the display contrast. (See Table 1)

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 29. 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, Outdoor Remote. 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.

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

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.

Blower Balance Point for Heating
Requires DHM connection from thermostat to heat pump system. Air to air heat pumps use a fast fan speed to circulate warm air for first stage heating. As outdoor temperatures drop, the heat pump produces less heat and a high fan speed makes the air from the ducts feel cooler. Blower Balance Point allows you to select an outdoor temperature to slow the fan speed so the air from the duct feels warmer. Select an outdoor temperature where the air from the ducts starts to feel cool (Installer Configuration Menu item 37). When the outdoor temperature drops to the selected temperature, the thermostat will slow the fan speed so the outlet air feels warmer.

Comfort Alert Codes
The Comfort Alert diagnostics product monitors the air conditioning outdoor systems with single phase Copeland Scroll compressors. Abnormal system and electrical conditions are indicated by flashing ALERT codes on the yellow LED on the Comfort Alert module. The flash codes are transmitted to the thermostat by the Comfort Alert Thermostat interface module. The Comfort Alert compatible thermostat displays “Call For Service” that flashes at the same rate as the yellow LED on the Comfort Alert module.

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 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.
Thermostat does not have Menu Screen Numbers	1. Earlier version of thermostat	To access the earlier version instruction sheet (37-6914E) go to www.white-rodgers.com, enter 1F95-1291 in Model Number Search
