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 off easily, while others may need to be removed by prying the cover off with a screwdriver.

WARNING
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 on page 43.

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.

Using your screwdriver, carefully unscrew one wire at a time from the terminal block and attach the corresponding wire label sticker.
Please note that not all terminals may be used and that there’s no standard colour code for thermostat wires, so your wire colors may vary. For your reference, we’ve included a terminal label reference chart on page 7 to help you connect the wires in your old thermostat to your new thermostat in case you get stuck.

Terminal labelling 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 Relay
Y, Y1	Y	Cooling Relay
G	G	Fan Relay
O	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

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 place
There’s only one R wire (RC, RH, R or R5) coming out of the wall	Leave the jumper wire in its place
Terminal RC and RH (or 5 or R5) are NOT connected by a jumper wire	Remove the jumper wire between RC     and RH

For terminals Y and W:

• If you have a heat pump with a reversing valve, connect Y and W with a jumper wire on your new thermostat.
• If you need help with labelling and wiring, please contact Customer Support at 877.654.9394 or email wr.techsupport@emerson.com — 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 labelled 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 the rear of the 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.

PROGRAMMING YOUR THERMOSTAT

Before you begin programming your thermostat, you should be familiar with its features and with the display and the location and operation of the thermostat buttons. Your thermostat consists of two parts: the thermostat cover and the base. To remove the cover, pull it straight out from the base. To replace the cover, line up the cover with the base and press until the cover snaps onto the base.

The thermostat buttons and switches

1. Raises temperature setting.
2. Lowers temperature setting.
3. TIME button.
4. PRGM (program) button.
5. RUN (run program) button.
6. HOLD temperature button.
7. FAN switch (ON, AUTO).
8. SYSTEM switch (COOL, OFF, HEAT).
   The display
9. Indicates the day of the week.
10. The flame icon is displayed when the SYSTEM switch is in the HEAT position. 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. Displays “CHANGE ” when the 2 “AAA” batteries are low and should be replaced.
    Only “CHANGE ” and “LO” in the minutes field are displayed when batteries are low with no system power.
12. Alternately displays current time and temperature. Displays “LO” in the minutes field when batteries are low.
13. The word “HOLD” is displayed when the thermostat is in the HOLD mode. “HOLD” is displayed flashing when the thermostat is in a temporary HOLD Mode.
14. Displays currently programmed set temperature (this is blank when the SYSTEM switch is in the OFF position).
15. Displays “FLTR” when the system has run for the programmed filter period as a reminder to change or clean your air filter.

Configuration menu

The configuration menu allows you to set certain thermostat operating characteristics to your system or personal requirements.
Press RUN to make sure the thermostat is in the run program mode, then press PRGM and RUN at the same time to enter the configuration menu. The display will show the first item in the configuration menu.
The configuration menu table summarizes the configuration options. An explanation of each option follows.
Press HOLD to change to the next menu item or press TIME to go backwards to the previous item in the menu. To exit the menu and return to the program operation, press RUN. If no keys are pressed within fifteen minutes, the thermostat will revert to normal operation.

1. Select Temporary Hold Time – The thermostat can hold any temperature you set it to for the amount of time you select on this option. Your choices are 0:00 to 8:00 hours in 15-minute increments. 0:00 disables the function
   Example:
   • You have selected 3:00 hours for the Temporary Hold period.
   • With the thermostat set to Heat or Cool, press HOLD for approximately five seconds until HOLD time (3:00 indicating 3 hours) appears as a setting reminder.
   • After releasing the button, “HOLD” on the display will blink.
   • Use or to set the temperature to your preference. The thermostat will maintain this temperature setting for 3 hours with “HOLD” blinking to remind you it is in Temporary Hold. After 3 hours the thermostat will go back to the program temperature and “HOLD” will no longer blink or display.
2. Select FA or SL (Fast or Slow) Heating Cycle Rate – The FA setting is frequently used for gas, oil or electric heat. The SL setting produces a longer heating cycle which is normal for hot water or steam (hydronic) systems. Both settings produce very accurate temperature control and can be set to your personal preference. FA cycles the system just under 1°F and the SL setting cycles at approximately 1.5°F.
3. Select backlit display – The display backlight improves display contrast in low lighting conditions. Selecting backlight ON will keep the light on for a short period after any key is pressed. Selecting OFF will keep the light off.
4. Select Energy Management Recovery OFF or ON – Energy Management Recovery (EMR) causes 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:
   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 degree the thermostat setpoint will change to 70° at 6:35 AM. Cooling allows more time per degree because it takes longer to reach temperature.
5. Select filter replacement run time – The thermostat will display “FLTR” after a set time of operation. This is a reminder to change or clean your air filter. This time can be set from 0 to 1950 hours in 50 hour increments. A selection of 000 will cancel this feature. When “FLTR” is displayed, you can clear it by pressing HOLD and RUN at the same time. This resets the timer and starts counting the hours until the next filter change. Changing the time in the menu also resets the timer.
6. Select Compressor Lockout LOC OFF or ON – Selecting LOC ON will cause the thermostat to wait 5 minutes before turning on the compressor if the heating and cooling system loses power. It will also wait a minimum of 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 feature is already present in their system. When the compressor time delay occurs it will fl ash the (snowfl ake icon) for about five minutes then turn on the compressor.
7. Select Temperature Display Adjustment 4 LO to 4 HI – Allows you to adjust the room temperature display
   +/- 4°. Your thermostat was accurately calibrated at the factory but you have the option to change the display temperature to match your previous thermostat.
8. Select F° or C° Readout – Change the display readout to Celsius or Fahrenheit as required.

Operating features

This section contains information about the many features of your new 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 your desired temperature.
  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. To engage this feature, 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 RUN button to start program operation again.
• CONFIGURATION MENU — Allows you to customize certain thermostat options.

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.

Planning your program
Look at the factory pre-programmed times and temperatures shown in the sample schedule. 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 pre-programmed times and temperatures, follow these steps.
Determine the periods and temperatures for your weekday and weekend programs. You must program
four periods for both the weekday and weekend programs. 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 weekday 1st period cooling start time and temperature).

SAMPLEHeating/Cooling Schedule Plan (Factory Program)

Use the following table to plan your program periods and the temperatures you want during each period. Fill in the complete table to have a record of your programs.
