REMOVING OLD THERMOSTAT

Turn off power

WARNING:To prevent electrical shock and/or equipment damage, disconnect electrical power to the system at the main fuse or circuit breaker box, or by flipping a switch at the air handler. Do not restore power until installation is complete.

To ensure the power to your heating and cooling system has been turned off, try to turn on heating or cooling by changing the temperature on your old thermostat.

Remove the old thermostat cover

Remove the old thermostat’s front cover from the wall base. Some covers pull of easily, while others may need to be released by using a screwdriver.

CAUTION:Your old thermostat may have a sealed glass tube containing mercury. Be careful not to damage the tube or dispose of the tube in your trash. For safe disposal information, please see Mercury Notice.

Label wires

Tip: Taking a picture with a camera or smartphone can help you not only remember how wires are connected to the terminals, but can also ensure that you label your wires correctly. Mislabeling the wires may result in a high energy bill or damage to your heating and cooling system.

Using your screwdriver, carefully unscrew one wire at a time from the terminal block and attachthe corresponding wire label sticker.

Please note that not all terminals may be used, and that there’s no standard color code for thermostat wires, so your wire colors may vary. For your reference, we’ve included a terminal label reference chart below to help you connect the wires in your old thermostat to your new thermostat in case you get stuck.

Terminal labeling reference chart 

If your current terminal has the following letter: Label the wires with the following letters: Terminal function

RH, R, R5, 5: RH: 24V Power (Heating)RC: RC: 24V Power (Cooling)W, W1, 4: W: Heating RelayY, Y1: Y: Cooling RelayG: G: Fan RelayO: O: Reversing Valve (for heat pump applications energized in Cool mode)B: B: Reversing Valve (for heat pump applications energized in Heat mode)

Identify jumper wire

For terminal RC and RH:

On your old thermostat, if…: Then, on your new thermostat…Terminal RC and RH are connected with a jumper wire: Leave the jumper wire in its placeThere’s only one R wire (RC, RH, R or R5) coming out of the wall: Leave the jumper wire in its placeTerminal RC and RH (or 5 or R5) are NOT connected by a jumper wire: Remove the jumper wire between RC and RH

For terminal Y and W:If you have a heat pump with reversing valve, connect Y and W with a jumper wire on your new thermostat.If you need help with labeling and wiring, please contact Customer Support at 877.654.9394 or email [email protected] — we’re here to help!

Remove old thermostat base

With all of your wires disconnected and properly labeled, you may now safely remove the thermostat base from your wall.

Tip: Worried about having your wires falling into your wall? Keep the wires secure by wrapping the them around a pencil.

MOUNTING AND WIRING YOUR NEW THERMOSTAT

Install new thermostat base

Mount your new thermostat base using the supplied screws. Drill holes and insert wall anchors to secure the thermostat base to the wall, if necessary.

Connect wires to corresponding terminal blocks

Match each labeled wire to it’s corresponding terminal on the mounted thermostat base. Insert each labeled wire into the hole of it’s matching terminal, and using the screwdriver, tighten the screw on the terminal block securely.

CAUTION:Take care when securing and routing wires so they do not short to adjacent terminals or rear of thermostat. Personal injury and/or property damage may occur.

Set switch and advanced wiring

If you have either a gas or oil furnace, set the switch to GAS.If you have an electric furnace, set the switch to ELEC.

Install the batteries and attach front cover

Install the included AAA alkaline batteries and push the front cover on to the thermostat base until it’s secure.

Turn on power

Snowflake icon () is displayed (non-flashing) when the SYSTEM switch is in the COOL position.Snowflake is displayed (flashing) if the thermostat is in lockout mode to prevent the compressor from cycling too quickly.11. Alternately displays current time and temperature.12.  is displayed when the 2 “AAA” batteries are low and should be replaced.Nothing else will be displayed. Earlier models display “LO BATTERY”.13. Displays currently programmed set temperature (this is blank when SYSTEM switch is in the OFF position).14. “HOLD” is displayed when the thermostat is in the HOLD mode.

Operating features

Now that you are familiar with the thermostat buttons and display, read the following information to learn about the many features of the thermostat.

  • SIMULTANEOUS HEATING/COOLING PROGRAM STORAGE — When programming, you can enter both your heating and cooling programs at the same time. There is no need to reprogram the thermostat at the beginning of each season.
  • TEMPERATURE OVERRIDE— Press or until the display shows the temperature you want. The thermostat will override current programming and keep the room temperature at the selected temperature until the next program period begins. Then the thermostat will automatically revert to the program.
  • HOLD TEMPERATURE — The thermostat can hold any temperature within its range for an indefinite period, without reverting to the programmed temperature. Press HOLD button. “HOLD” will be displayed. Then choose the desired temperature by pressing or The thermostat will hold the room temperature at the selected setting until you press the RUN button to start program operation again.
  • ENERGY MANAGEMENT RECOVERY — Energy Management Recovery (EMR) causes the thermostat to startheating 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. Cooling will start approximately 15 minutes early for every 1° because it takes longer to reach temperature. Clipping W903 jumper will disable EMR.Example: You select EMR and have your heating 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 degreethe thermostat setpoint will change to 70° at 6:35 AM.
  • °F/°C CONVERTIBILITY — The factory default setting is Fahrenheit. Clipping W904 jumper on the circuit board will alter this feature to Celsius temperature setting.
  • LOW BATTERY INDICATOR — If the 2 “AAA” alkaline batteries are low and should bereplaced, the display will be blank except for . When the batteries are low, pressing any button will cause the display to operate for ten seconds. After ten seconds, the display will be blank except for . After has been displayed for 4 weeks, the thermostat will raise the temperature 10° above your set point in COOL mode and drop the temperature 10° below your setpoint in HEAT mode. You cannot program with low batteries, but you can override setpoint temperature.
  • TEMPERATURE DISPLAY ADJUSTMENT — Your new thermostat has been accuratelyset in our factory.However, if you wish, you may adjust your new thermostat temperature display to match your old thermostat.This can be accomplished (within a ±3° range) as follows:1. Press PRGM and RUN buttons at the same time.2. Press or to adjust the displayed temperature to your desired setting.3. Press RUN to resume normal program operation.
  • DISPLAY BACKLIGHT — (Not available on earlier models.) The display backlight improves display contrast in low lighting conditions. Selecting backlight ON will turn the light on for a short period of time after any button ispressed.Selecting backlight OFF (default) will keep the light off. Turn the display backlight feature ON as follows:1. Press TIME and RUN buttons at the same time. The display will show “d-L” and “OFF” alternately.2. Press or to change “OFF” to “ON”
Programming your thermostat

This section will help you plan your thermostat’s program to meet your needs. For maximum comfort and efficiency, keep the following guidelines in mind when planning your program.

  • When heating (cooling) your building, program the temperatures to be cooler (warmer) when the building is vacant or during periods of low activity.
  • During early morning hours, the need for cooling is usually minimal.

Look at the factory preprogrammed times and temperatures shown below. If this program will suit your needs, simply press the RUN button to begin running the factory preset program.

If you want to change the preprogrammed times and temperatures, follow these steps.

Determine the time periods and temperatures for your weekday and weekend programs. You must program four periods for both the weekday and weekend program. However, you may use the same heating and cooling temperatures for consecutive time periods. You can choose start times, heating temperatures, and cooling temperatures independently for both weekday and weekend programs (for example, you may select 5:00 AM and 70° as the weekday 1st period heating start time and temperature, and also choose 7:00 AM and 76° as the weekday1st period cooling start time and temperature). Use the table at the bottom of the page to plan your program time periods and the temperatures you want during each period. You may also want to look at the sample program table to get an idea of how the thermostat can be programmed.

This also resets the factory defaults to the configuration menu and program. If the thermostat has power, has been reset and still does not function correctly contact your heating/cooling service person or place of purchase.

BatteriesFor optimum performance, we recommend replacing batteries once a year with fresh “AAA” alkaline batteries.

Symptom:Possible Cause:Corrective Action.

1. Heat, Cool or Fan Runs Constantly.:

  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.:

Check each wire connection to verify they are not shorted or touching together. No bare wire should stick out from under terminal screws. Try resetting the thermostat. 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.

2. No Heat:

  1. Pilot light not lit.
  2. SYSTEM Switch not set to HEAT.
  3. Loose connection to thermostat or system.
  4. Furnace Lock-Out Condition. Heat may also be intermittent.
  5. Heating system requires service or raise thermostat requires replacement.:

Re-light pilot.Set SYSTEM Switch to HEAT and raise setpoint temperature above room temperature. Verify thermostat and system wires are securely attached.Many furnaces have safety devices that shutdown when a lock-out condition occurs. If the heat works intermittently contact the furnace manufacturer or local service person for assistance.Diagnostic: Set SYSTEM Switch to HEAT and the setpoint above room temperature. Within a few seconds the thermostat should make a soft click sound. This sound usually indicates thethermostat 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 service person to verify the heating is operating correctly.

3. No Cool:

  1. SYSTEM Switch not set to COOL.
  2. Loose connection to thermostat or system.
  3. Cooling system requires service or thermostat requires replacement.

Set SYSTEM Switch to COOL and lower setpoint temperature below room temperature. Verify thermostat and system wires are securely attached.Same procedure 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.

4. 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 screws. Try resetting the thermostat as described above. If the condition persists themanufacturer 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.

5. Furnace 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 normally provide precise temperature control and may cycle faster than some older mechanical models. A faster cycle rate means the unit turns on and off more frequently but runs for a shorter time so there is no increase in energy use.If you would like to increase the cycle time, clip Jumper W-905 as mentioned in the instructions for Hydronic Heating Systems. It is not possible to shorten the cycle time. If an acceptable cycle rate is not achieved as received or by clipping W-905 contact a local service person for additional suggestions.

6. Cooling cycles Too Fast or Too Slow (narrow or wide temperature swing):

  1. The location of the thermostat and the size of the Cooling System can influence the cycle rate.:

The cycle rate for cooling is fixed and can not be adjusted. Contact a local service person for suggestions.

7. Thermostat Setting and Thermostat Thermometer Disagree:

  1. Thermostat thermometer setting requires adjustment.:

The thermometer can be adjusted +/- 3 degrees. See Temperature Display Adjustment in the Operation section.

8. Thermostat Does Not Follow Program:

  1. AM or PM set incorrectly in program.
  2. AM or PM set incorrectly on the clock.
  3. Voltage spike or static discharge:

Check current clock and programsettings including the AM or PM designations for each time period. If a voltage spike or a static discharge occurs use the Reset Operation listed above.

9. Blank Display and/or Keypad Not Responding:

  1. Voltage spike or static discharge
  2. Battery change required:

Replace batteries and check heat/cool system for proper operation. If a voltage spike occurs use the Reset Operation listed above.
