CAUTION: This thermostat is protected against normal static electric discharges; however touching a grounded metal object before touching your thermostat will minimize the risk of damaging the unit in extremely dry weather. 4. SELECTING A LOCATION On replacement installations, mount the new thermostat in place of the old one unless the conditions listed below suggest otherwise. On new installations, follow the guidelines listed below. 1. Locate the thermostat on an inside wall, about 5 ft. (1.
• Your thermostat is a precision electronic instrument; please handle it with care to avoid damage. 5. REMOVE OLD THERMOSTAT 1. Turn OFF the electricity to all heating and cooling components. Do not turn the OFF electricity back on until all work is completed. 2. Remove the cover and 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 the color of the wire that is connected to it.
3. Remove the body from the thermostat’s base by pressing the thumb latch at the bottom center of the unit and swinging the body away from the base. NOTE: If you are mounting the base to soft material like plasterboard or if you are using the old mounting holes, the screws may not hold. Drill a 3/16 in. (4.8mm) hole at each screw, and insert the plastic anchors provided. 4. Hold the base against the wall. Route the wires through the hole below the terminal block.
• All of the dashed wires shown in the following wiring diagrams are either optional, or their usage depends upon your specific system type or brand. For example: Diagram #1 shows the fan wire as optional. If your system does not have a fan, than this terminal will not be used. • The optional “C” terminal is used for powering the thermostat by the 24 Volt system power. This can be used alone, or in addition to installing batteries.

8. HARDWARE SETUP OPTIONS NOTE: All of the settings, options, and components listed in the following section are located on the rear of the thermostat, on the circuit board. GAS/ELEC. FAN OPERATION This is a plastic jumper cap, which is labeled as JP2. This jumper must remain installed, and can be in one of two positions, GAS or ELECTRIC. ELECRIC JP2 GAS This setting changes how the system’s blower fan (if applicable) is controlled while in HEAT mode, and with the Fan switch in the AUTO position.
[1] SYSTEM MODE This setting tells the thermostat about the type of heating and cooling equipment that it is controlling, so that the system is operated properly. This switch needs to be in the OFF (NON-HP) position if you have a furnace or conventional heating and air conditioning system. If you have a Heat Pump system, the switch needs to be in the ON (HP) position; this is applicable even if your heat pump system has an auxiliary heat stage that is a gas furnace.
[4] SCALE This setting determines how the thermostat displays all temperatures on the screen. Switch position OFF is F°, and ON is C°. [5] TIME This setting determines how the thermostat displays the clock and all other time values on the screen. Switch position OFF is 12 HR (US Standard), and ON is 24 HR (Military Time). [6] BATTERY MONITOR This determines whether the internal battery voltage monitor watches the condition of the batteries that are installed in the thermostat.
NOTE: When you are finished performing your installation and setup options, please remove the thin plastic film that is protecting the LCD display screen on the front of the thermostat. This plastic may or may not be present, and is evident by the appearance of fake digits appearing on the display screen. 10. FRONT PANEL ITEMS RESET The RESET button is a small recessed push button that is located right above the NEXT button behind the front door.
needed. With the Fan switch in the ON position, the fan will operate even when the Temperature Mode switch is in the OFF position to provide air circulation only. When the fan is running, the word “FAN” is displayed in the temperature portion of the display screen. NOTE: The Fan Mode switch only works if your system provides a wire for the thermostat’s “G” wire terminal, to control a blower fan.
buttons, adjust the clock to the current time, and make sure that the proper AM or PM indication is observed as appropriate. To assist with large adjustments, the clock digits will increment rapidly in either direction if the UP or DOWN buttons are held pressed for more than a few seconds.
TEMPERATURE OVERRIDE A Temperature Override occurs in Run mode, in either Heat or Cool, anytime the user adjusts the set temperature to a value that differs from the stored program temperature for that day and time. When the thermostat is in an Override, the word “OVERRIDE” will appear in the temperature area of the display. The thermostat will temporarily maintain thermal control using this new set temperature, until the start time of the next program period is reached.
EMERGENCY HEAT (Heat Pump Configuration Only) While in normal Heat mode with the rotary dial in the RUN position, one single press of the COPY/EMER button will activate Emergency Heat mode. A single press again will end Emergency Heat mode, and return back to normal Heat mode. While in Emergency Heat mode, the word “EMER” will be shown in the temperature portion of the display screen.
AIR FILTER MONITOR In systems that have a blower fan and air ducts, this feature is to assist you with proper maintenance and periodic replacement of the filter located in your heating or cooling system. The Air Filter Monitor counts the duration of filter usage that has occurred, since the last time the Filter Monitor has been reset. The Air Filter Monitor is for information only, and does not affect the operation of your heating or cooling equipment.
save energy in some cases. There is only one Swing setting, and this determines the cut-in and cut-out points for both the first and second stages (if present), and affects both heating and cooling. To change the Swing setting, ensure that the System Mode switch is in the OFF position and the rotary dial is in RUN. Press the HOLD button for at least 2 seconds. The words “SET:” and “SWING” will appear on the screen with a single digit shown.
OFFSET: After the swing value has been accepted, the words “SET:” and “OFFSET” will be shown on the screen. This setting is shown as a number of degrees, and is similar in nature to the swing however it only effects the operation of the second (auxiliary) heating stage, if present. The setting range for Offset is from 0 to 9 degrees. When set to 0 degrees, the second heating stage is disabled.
four-digit code to unlock them. You may use either the default lock code of “0000”, or your own code number (see “TO CHANGE THE LOCK CODE:”). TO LOCK THE THERMOSTAT: Ensure the rotary dial is in the RUN position. Press the NEXT button for at least 2 seconds. The words “ENTER CODE” will appear on the screen, above “0000”. Enter the correct code by using the UP/DOWN buttons to change the flashing digit, and the NEXT button to advance to the next digit. Press the NEXT button again for at least 2 seconds.
TO CHANGE THE LOCK CODE: First ensure that the thermostat is unlocked and the rotary dial is in the RUN position. Press the NEXT button for at least 2 seconds. The words “ENTER CODE” will appear on the screen, above “0000”. Now press the HOLD button for at least 2 seconds. The words “SET CODE” will appear on the screen, along with “0000”. Enter your desired code by using the UP/DOWN buttons to change the flashing digit, and the NEXT button to advance to the next digit.
13. PROGRAMMING SET HEAT PROGRAM Rotate the dial to HEAT PROGRAM. You will be programming the heat periods for all seven days, one after the other starting with Monday. The first period is MORN. Using the UP and DOWN buttons, set the start time for this period, and then push the NEXT button to proceed. Now set the desired set temperature for the MORN period using the UP and DOWN buttons, and push NEXT to proceed.
will appear on the screen, with one of the days flashing above. Using the UP/DOWN buttons, select the day that you want to copy from. Press the NEXT button once. Your “copy from” day should be on steady with the following day flashing. Use the UP/DOWN buttons to select the day that you would like to copy to. A single short press of the COPY button will perform the copy, and the flashing day will advance to the next following day.
swinging the body towards you, up and away from the base. Remove the used batteries from the battery tray and discard appropriately. Install two new Energizer ® or DURACELL ® “AA” size alkaline batteries into the battery tray. Observe the polarity markings shown in the battery compartment to ensure proper installation. When finished, hang the top of the unit by the tabs at the top corners of the base, and then snap the bottom of the unit into place. Do not use unnecessary force.
