Screwdrivers, wire stripper / cutter, and possibly a drill with assorted bits (new installations only).

1. Turn OFF the electricity to all heating and cooling components. Do not turn the electricity back on

until all work is completed.

2. Remove the front portion of your old thermostat to expose the wiring connections.

3. Write down the letters printed near each wire terminal that is used, and also the color of each wire

that is connected to it. Self-adhesive wire labels are also enclosed.

4. Carefully remove the wires one at a time, and bend them in a manner so that they do not fall back

inside the wall. Do not allow bare wire ends to touch each other.

5. oosen the mounting screws for the old thermostat and carefully remove it from the wall.

On replacement installations, mount the new thermostat in place of the old one unless the conditions listed below

suggest otherwise. On new installations, please follow these general guidelines:

1. Mount the thermostat on an inside wall, about 5 ft. (1.5m) above the floor.

2. Do not locate the thermostat where air circulation is poor such as in a corner, alcove, or behind a door that is normally

left open.

3. Do not locate the thermostat where unusual heating or cooling conditions may be present, such as: direct sunlight,

above a lamp, television, or radiator, or on a wall next to an exterior door or window.

4. Do not locate in a damp environment, as this can lead to corrosion that may shorten thermostat life.

5. If painting or construction work is still ongoing, cover the thermostat completely or wait until this work is complete

before installation.

1. Strip wire insulation leaving only 3/8 in. (9.5mm) bare wire ends, and clean off any corrosion present.

2. Fill the wall opening with non-combustible insulation to prevent drafts from affecting the thermostat’s normal

operation.

3. Route the wires through the opening in the new thermostat base plate, and hold the base against the wall. Try to line

up the screw holes from the prior thermostat, and install the mounting screws.

4. If the previous holes cannot be used, hold the thermostat base against the wall so that it appears straight and level

(position the base for best appearance) and mark for the new screw holes. Attach the base to the wall using the

screws provided (use the supplied plastic anchors if needed when mounting to a soft material such as drywall).

INSTALLATION OF NEW THE MOSTAT:

TOOLS YOU MAY NEED:

1. When attaching the wires to the thermostat, please ensure that the bare wire ends are held A the way into the

terminal block while the screw is being tightened.

2. Securely tighten all of the electrical terminal screws, including any unused ones. Be careful not to over tighten the

screws, they only need to be snug.

** Complete heating and/or cooling system wiring can be found in the WI E IDENTIFICATION AND WI ING

SCHEMATICS section of this instruction sheet. The schematics shown provide component information for brand

new installations or for unreferenced wires.

On the circuit board, there are hardware settings called “jumpers”. These settings can be changed from their default

values by removing its black cap and reinstalling the cap so that it is positioned

on only one (1) of the metal pins, and not both. A C OSED jumper means the

black cap is on both of the metal pins, and an OPEN jumper means the cap is on

only one (1) metal pin.

HA DWA E ESET BUTTON: A change to ANY of the jumper settings will not be

recognized by the thermostat until the white HARDWARE RESET button on the

circuit board is pressed.

JP1 (SYSTEM): [C OSED = Furnace, default] This setting is used for the majority of all heating

systems that are not heat pumps. Examples for this setting would be: natural gas furnace, hot

water baseboard heat, and oil heat. [OPEN = Heat Pump] Use this setting if you have a heat

pump unit (which looks just like an outside air conditioning unit, but is used for both cooing and

heating).

JP2 (DELAY): [C OSED = 5 Minutes, default] This setting changes the length of time that the

system must remain either on or off before it will switch to the alternate on or off state. The

main purpose of this setting is to provide equipment protection by preventing brief or undesirable

frequent on/off cycling. [OPEN = 2 Minutes] This can be used to decrease the minimum amount

of time that occurs between cycles, and may be desired for hot water radiator systems to reduce

overshoot.

JP3 (SCALE): [C OSED = Fahrenheit, default] All temperature values are displayed in F˚ degrees.

[OPEN = Celsius] This setting displays all temperature values in C˚ degrees.

JP4 (FAN): This option is located separately from the first three settings shown above.

[C OSED = Gas, default] This setting lets the heating system itself control the blower fan

automatically. Types of systems that would typically use the “Gas” fan setting would be: natural

gas furnace, propane furnace, and oil furnace.

[OPEN = Elec] This setting runs the system’s blower fan when heat is called for, and is required

for systems that do not control their own fan while in HEAT mode. Heat pump systems, and units

with an electric heating element typically require this setting.

HEAT / OFF / COOL, SYSTEM MODE SWITCH: Set this switch to HEAT to control your heating system, and COO to control

your cooling system. The OFF position will disable both the heating and cooling units.

AUTO / ON, FAN SWITCH: When this switch is in AUTO, the blower fan (if present in your system) will automatically cycle

on and off by itself when heating or cooling is running. When in the ON position, the blower fan will run constantly with

or without a demand for heating or cooling, even in OFF mode.

UP AND DOWN BUTTONS: While in HEAT or COO mode, you can use the UP and DOWN buttons to raise or lower the set

temperature. When the thermostat is powered up for the first time, it will use the default set temperatures of 68°F

(20°C) for Heat mode and 72°F (22°C) for Cool mode. NOTE: when you adjust the temperature using UP and DOWN

buttons, the change occurs immediately and you do not have to press the SAVE button to accept the changes.

SAVE BUTTON: Reducing the amount of heating and cooling energy you use will directly save you money. The SAVE

feature allows you to use just one button press to easily decrease the current set temperature by 5F (3°C) degrees while

in Heat mode (or raise the set temperature by 5°F (3°C) degrees while in Cool mode). When you leave the house, simply

press the SAVE button one time to put the thermostat into Save mode, and the word “SAVE” will be shown on the screen.

When you return home, press the SAVE button again to cancel the Save mode and return back to the previous set

temperature that you were using originally.

After Save mode has been started, you can adjust the energy-saving set temperature by using the UP and DOWN buttons

in either direction. Just like above, one more press on the SAVE button will cancel the Save mode and return back to the

original set temperature that was used prior to starting Save mode.

LCD DISPLAY BACKLIGHT: The display screen has a light that will assist viewing at nighttime, or in low lighting areas.

When any front panel button is pressed, the screen will light up for approximately 10 seconds. Any button presses that

occur while the backlight is on, will reset the 10 second timer, causing the screen to remain illuminated for an additional

10 seconds.

STATIC NOTICE: This thermostat is protected against normal minor static electric discharges, however to minimize the

risk of damaging the unit in extremely dry weather, please touch a grounded metal object before touching your

thermostat.

OPE ATING INST UCTIONS:

TEMPE ATU E SWING: The amount of temperature variation between load-on and load-off is changed by adjusting the

swing setting. The default value for this thermostat is #4, and the adjustment range is from #1 to #9. A smaller swing

number makes the temperature control more precise and constant, and increases the number of cycles per hour. A larger

swing number will produce a greater variation between load-on and load-off events, and decreases the number of cycles

per hour.

To adjust the Swing setting: Set the thermostat to OFF mode using the System Mode switch, and hold down the SAVE

button for at least 5 seconds. When the screen changes to a single digit, this is the current Swing setting value and it

can be adjusted using the UP or DOWN buttons. The thermostat will return back to the normal Run mode screen if no

buttons are pressed for 4 seconds.

TEMPE ATU E CALIB ATION: This thermostat is accurately calibrated at the factory, and in most cases alteration to this

setting should not be required. The Calibration feature allows you to manually offset the room temperature measurement

by as much as plus or minus 5°F (3°C) degrees from its original value. 0°F (0°C) is the default setting.

To adjust the Calibration setting: Set the thermostat to OFF mode using the System Mode switch, press both the UP and

DOWN together for at least 2 seconds. When the screen changes to a single digit, this is the current Calibration setting

value and it can be adjusted using the UP or DOWN buttons. The thermostat will return back to the normal Run mode

screen if no buttons are pressed for 4 seconds.

This thermostat is powered by two “AA” Alkaline batteries. The batteries should be replaced AT EAST once per year (or

sooner, if the “ OW BAT” battery symbol appears in the display screen). When the O BAT symbol is shown, the

temperature digits will also display the word “ o”. The batteries are located on the back of the circuit board, and can be

accessed by pulling the front portion of the thermostat straight outwards and removing it from the wall. When installing

new batteries, we recommend using only brand new Energizer®or DURACE ®, “AA” size alkaline batteries. Please

observe the polarity markings shown in the battery compartment to ensure proper installation. When finished, line up the

front of the thermostat to the base, and firmly press together.
