TOOLS YOU MAY NEED:

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

EMOVAL OF OLD THERMOSTAT:

1. Tur n OFF the electricity to all heating and cooling components. D o not turn the electricity back on until all work is completed.

2. Remove the front portion of your old thermostat to expose the wiring con ne ct io ns .

3. Write dow n the l etters printed near each wire terminal that is used, and a ls o 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 be nd 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. Loosen the mounting screws for the old thermostat and carefully remove it from the wa ll .

THERMOSTAT MOUNTING LOCATI ON:

On replacement installations, mount the new thermostat in place of the old one unless the conditions listed b el ow 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 wh er e air circula tion is p oo r such as in a corner, alcove, or behind a door that is normally left open.

3. Do not locate the thermostat wh er e unusual h ea ting or coo li ng conditions m ay 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 c an lead to corrosion tha t may shorten thermostat l if e.

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

INSTALLATION OF NEW T HERMOSTAT:

1. Strip wire insulation le aving only 3/8 in. (9.5mm) bare wire ends, and clean off any c or ro si on present.

2. Fill the wa ll opening with non-combustible insula ti on to prevent drafts from affecting the thermostat’s normal operation.

3. Route the wires through the opening in the n ew thermostat base plate, and ho ld the base against th e wall. Try to line up the screw ho le s from the prior thermosta t, and install the mounting screws.

4. If the previous holes cannot be used, hold the thermosta t base against the w al l so that it a ppears straight and level (position the base fo r best appearance) and m ar k for the new screw holes. Attach the base to the wall using t he screws provided (use th e supplied plastic anchors if needed when mounting to a soft ma terial such as drywall).

1. When at ta ch in g the wires to the thermostat, please ensure that the bare wire ends are held ALL the way into the terminal block while th e screw is being tightened.

2. Securely tighten all of the electrical terminal screws, including any unused ones. Be careful not to over ti gh te n the screws, they only need to be snug.

SYSTEM CONFIGURATION AND SETUP OPTIONS:

On the circuit bo ar d, there are hardware settings called “jumpers”. These settings can be changed from their d ef au lt values by removing it s black cap and re in st al li ng the ca p so th at it is positioned on only one ( 1) of the metal pins, and not both. A CLOSED jumper means the black cap is on both of the m et al pins, and an OPEN jumper means the c ap is on only one (1) me ta l pin.

HARDWARE RESET BUTTON: A change to ANY of the ju mp er settings will not be recognized by the t he rm os ta t until the white HA RD WARE RESET button o n the circuit board is pr es se d.

JP1 (SYSTEM): [CLOSED = Furnace, default] This setting is used for the majority of all heating systems that are not heat pumps. Examples fo r this setting would be: natural gas furnace, hot water baseboard heat, and oil heat. [ OP EN = Heat Pump] Us e this setting if you have a heat pump unit (which lo ok s just like an outside air conditioning unit, but is used for both cooing and heating).

JP2 (DELAY): [CLOSED = 5 Minutes, default] This setting changes the length of time th at the system must remain ei th er on or off before it will switch to the alternate on or off state. T he main purpose of t hi s setting is to provide equipment protection by preventing brief or u nd es ir ab le frequent on/off cycling. [OPEN = 2 Minutes] This can be us ed to decrease the minimum amount of time that occurs between cycles, and may be desired for hot wat er radiator systems to r ed uc e overshoot.

JP3 (SCALE): [CLOSED = Fahrenheit, default] All temperature values are displayed in F˚ degrees. [OPEN = Celsius] This setting displays all temperature values in C˚ degrees.

JP4 (FAN): This o pt io n is loca ted separately from the first three setti ng s shown above.

[CLOSED = Gas, default] This setting le ts the heating system it se lf control the blower fa n automatically. Types of systems that would typically use the “Gas” fan setting w ou ld be: natural gas furnace, propane furnace, and oil f ur na ce .

[OPEN = Elec] This setting runs the system’s blower fan when heat is called for, an d is required for systems that do not control their o wn fan while in HE AT mode. Heat pump systems, and un it s with an electric he ating element typically require th is setting.
