If your system does not have a fan, than this terminal will not be used. Depending upon the brand of your specific system or thermostat, your terminal letters may not match exactly. Terminal letters shown in gray represent other possible wiring designations that you might see on your existing thermostat terminals. This can be used alone, or in addition to installing batteries as a backup. NOTE: connecting the System Common wire to the thermostat is not necessary for heating and cooling to function properly.

If painting or construction work has yet to be completed, cover the unit completely or do not install it. This may damage the thermostat and void your warranty.
Turn OFF the electricity to all heating and cooling components. Do not turn the electricity back on until all work is completed. Remove the cover and front portion of your old thermostat to expose the wiring connections. Write down the letters printed near each wire terminal that is used, and the color of the wire that is connected to it.
Using the enclosed labels, attach a label to each of your wires so that the letter matches the marking on your existing thermostat. When they are all labeled, carefully remove the wires one at a time, making sure that they do not fall back inside the wall. Do not allow any of the bare wire ends to touch each other, or any parts on the thermostat.
Loosen all of the screws on the old thermostat and remove it from the wall. Fill wall opening with non-combustible insulation to prevent drafts from affecting the thermostat. Be careful not to drop the unit or disturb electronic parts. Leave the door closed while the body is being removed from the base. 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.
Hold the base against the wall. Route the wires through the hole below the terminal block. Position the base for best appearance to hide any marks from an old thermostat. Attach the base to the wall with the two screws provided. Wires must be trapped between the black clamps and the brass terminals as shown here.

The schmatics shown provide component information for brand new installations or for unreferenced wires.
The hardware reset is a push button that is located on the right edge of the circuit board, just above the battery location. When any of the following items are changed, the hardware reset button must be pushed for the change to be recognized. User temperature programs are not erased when a hardware reset is performed. The Furnace Mode setting determines how the thermostat controls the fan operation. This setting has no effect in Cool Mode.
While in Heat Mode, with the jumper in the Gas position, the fan is controlled by your furnace. With the jumper in the Electric position, the fan is controlled by the thermostat and is turned on when the heating terminal becomes energized. The following option settings are all located within a group of small switches labeled 1 through 6 as shown below, and are located in the center of the circuit board.
This sets the minimum length of time that the thermostat must remain with Heat or Cool either On or Off, before it will automatically switch to the alternate On or Off state. This feature prevents rapid cycling and provides compressor protection for cooling units. This determines how the thermostat displays the clock and all other times on the screen. This determines how the thermostat displays all temperatures on the screen.
This determines how the remaining filter life will be displayed on the filter bar graph at the bottom of the LCD screen. In the Days mode, the display will count down the number of calendar days remaining before a filter change is recommended. Either option will display the visual bar graph. This determines whether the internal battery voltage monitor watches the condition of the batteries that are installed in the thermostat.
This setting should always remain enabled unless the thermostat is being powered by System Power alone, without any batteries present. The software reset is a small recessed push button that is located right above the NEXT button. This button can be pushed with a pencil or the end of a paper clip. This reset clears all of the heating and cooling programs, filter settings, and other user changeable preferences to their default values.
You should write down your heating and cooling program times and temperatures prior to using the software reset. There are two mode switches on the front, a Temperature mode switch and a Fan mode switch.
In the winter, set the system switch to HEAT to control your heating system. In the summer, set the switch to COOL to control your air conditioner. In the spring and fall or when the windows are open, you can set the switch OFF.
Setting the Fan mode switch to AUTO, automatically runs your system's blower fan as required only during heating and cooling activation. About the Lux TXU Lux TXU specifications. Related product manuals. Where is the best location to place the thermostat?
