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 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.
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 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.

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 backup.
*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.

WIRING DIAGRAMS

Figure 2 – Single Stage or Multi-Stage System (No Heat Pump) with Single Transformer

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 twotransformer system.
You can configure the thermostat for use with the following fossil fuel systems:
SINGLE STAGE (SS 1) gas, oil or electric.
MULTI-STAGE (MS 2) gas, oil or electric.
After wiring, see INSTALLER CONFIGURATION section for proper thermostat configuration.

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.
HEAT PUMP TYPE 1 (HP 1). Single stage compressor system; gas or electric backup.
HEAT PUMP TYPE 2 (HP 2). Multi-stage compressor or two compressor system with gas or electric backup.
After wiring, see INSTALLER CONFIGURATION section for proper thermostat configuration.

Figure 4 – Humidity and Sensors

Humidification Te rminal, 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 #41| 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| Supply voltage to  remote temperature sensor| Remote temperature sensor signal| Supply voltage to  remote temperature sensor

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.

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 screen reference number 33) (4 heat/2 cool)
   SS1 – Single Stage System (3 wire zone 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 nonprogrammable mode, the step for EMR will be skipped, as this feature will not be available in this mode.

5. 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.

6. 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.

7. 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.

8. 9 & 10. 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

9. 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

Auto Schedule Heat is a fast way to program all the heating temperatures during the day to a comfortable temperature and then lower the temperature 6° at night. Auto Schedule Cool will program all of the cooling time periods to the  same temperature.
Note: Auto Schedule is available only when the thermostat is first powered on, after the thermostat has been reset, or anytime you turn AS on in the Configuration Menu (item 17 AS Heat or 18 AS Cool). After use in heating and cooling, Auto Schedule on the display will change to Humidity.
Heating Example:

1. In Heat mode, press Auto Schedule once.
2. Press or to select a comfortable day time temperature (example 72°).
3. Press Auto Schedule again. Your thermostat is now programmed for 72° from 6:30 AM until 10:30 PM at 72°. At 10:30 PM, your thermostat will set back 6° to 66°.
   Your heating program for each day of the week will look like this:

Programmable Fan Option
In the Set Schedule mode, the Fan key is used to select the fan operation during a program period. The default state of the Fan key is FAN Auto (fan runs during a call for cool but not on a call for heat). It can be changed to FAN Prog (fan   runs during a program period). Each press of the FAN key will change the mode of the fan between Auto and Prog. In the Run mode, when a program period that has FAN Prog begins, the fan will turn on and stay on during the complete period. The display will show FAN On Prog. Pressing the FAN key will change FAN On Prog to On (fan running continuously) or Auto.
To return to FAN On Prog, press Run Schedule.

Energy Saving Factory Pre-Program
This thermostat is programmed with the energy saving settings shown in the table below for all days of the week. If this program suits your needs, simply set the thermostat clock and press the RUN key. The table below shows the factory set heating and cooling schedule for all days of the week.

• You can eliminate these two program periods in the configuration menu (reference #5) if the building is occupied all day.
  Day period will change to 6:00 AM and 70° and can be programmed as required.
  Planning Your Program – Important
  The Heating and Cooling Program schedules below allow you to pencil in your own program times and temperatures.
  The thermostat 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 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.

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 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, 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.
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 o F to 140 o F Indoor temperature range is 32 °F to 99 °F

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 33 or 34.
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 34) from 01 to 09 can be selected. A higher temperature or dual fuel setting will provide a smaller stage separation between the heat pump  and Aux to give more comfort. A lower temperature or number will provide a larger stage separation for more economy.
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.

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.

TROUBLESHOOTING

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.
