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 off 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 on page 27.

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 attach the 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 to help you connect the wires in your old thermostat to your new thermostat in case you get stuck.

Terminal labeling reference chart

Identify jumper wire
For terminal RC and RH

For terminals 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 wr.techsupport@emerson.com — we’re here to help

Remove the 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 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 its corresponding terminal on the mounted thermostat base. Insert each labeled wire into the hole of its 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.

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

Turn on power
Turn on your power at the source.

Congratulations! You’ve completed the thermostat installation process

CHECK THERMOSTAT OPERATION

Tip
If at any time during testing your system does not operate properly, please contact Customer Support at 877.654.9394 or email wr.techsupport@emerson.com

Note
To prevent static discharge problems, touch the side of the thermostat to release static build-up before touching any keys.

If at any time during testing your system does not operate properly, contact a qualified service person.

Fan operation
If your system does not have a G terminal connection, skip to Heating System.

1. Turn on the power system
2. Move FAN switch to ON position. The blower should begin to operate.
3. Move FAN switch to AUTO position. The blower should stop immediately.

Cooling system

CAUTION
To prevent compressor and/or property damage, if the outdoor temperature is below 50°, DO NOT operate the cooling system

This thermostat has a time delay between cooling cycles to allow the head pressure in the compressor to stabilize. If the temperature is adjusted to call for cool within 5 minutes of the last cycle the snowflake icon will blink indicating the thermostat is locked out. After 3 to 5 minutes, the compressor will start and the snowflake icon will stop flashing. This helps prevent the compressor from cycling too quickly and is a normal operation for the thermostat.

1. Mose SYSTEM switch to COOL position.
2. Press  to adjust the thermostat setting below room temperature. The blower should come on immediately on high speed, followed by bold air circulation
3. Press   to adjust the temperature setting above room temperature. The cooling system should stop operating.

Heating system

1. Move SYSTEM switch to HEAT position. If the heating system has a standing pilot, be sure to light it.
2. Press   to adjust the thermostat setting to room temperature. The heating system should begin to operate.
3. Press    to adjust the temperature setting below room temperature. The heating system should stop operating.

Before you begin using 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, gently pull it straight out from the base. To replace the cover, line up the cover with the base and press gently until the cover snaps onto the base.

The thermostat buttons and switches

1. (Up arrow) Raises temperature setting.
2. (Down arrow) Lowers temperature setting.
3. FAN switch (ON, AUTO).
4. SYSTEM switch (COOL, OFF, HEAT).

The display

• Flame is displayed when the SYSTEM switch is in the HEAT position  is displayed (non-flashing) when the SYSTEM switch is in the COOL position.   is displayed (flashing) when the compressor is in lockout mode.
• Displays current temperature.
• is displayed when the 2 “AAA” batteries are low and should be replaced. Nothing else will be displayed.
• Displays currently set temperature (this is blank when the SYSTEM switch is in the OFF position).

 

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 SETPOINT STORAGE
  You can enter both your heating and cooling setpoints at the same time. There is no need to re-enter the thermostat at the beginning of each season.
• TEMPERATURE SETTING
  Press  or   until the display shows the temperature you want. The thermostat will keep the room temperature at the selected temperature.
• °F/°C CONVERTIBILITY
  The factory default setting is Fahrenheit. Clipping W904 jumper on the circuit board will alter this feature to Celsius temperature setting. See diagram on page 11.
• LOW BATTERY INDICATOR
  If the 2 “AAA” alkaline batteries are low and should be replaced, 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 setpoint 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 accurately set 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  or  at the same time for two seconds with the SYSTEM switch in OFF position.
2. Press  or   to adjust the displayed temperature to your desired setting.
3. Move the SYSTEM switch from OFF to exit the feature.

• DISPLAY BACKLIGHT
  (Not available on earlier models.) The display backlight improves display contrast in low lighting conditions. Selecting the backlight ON will turn the light on for a short period of time after any button is pressed. Selecting the backlight OFF (default) will keep the light off. Turn the display backlight feature ON as follows

1. Press  and  at the same time for two seconds with the SYSTEM switch in the HEAT position.
   The display will alternately show “-L” AND “FF” (off).
2. Press  or  to change “FF” to “ON”.
3. Move the SYSTEM switch to OFF to exit the feature.
