LUX TX100Ea - Operation, Wiring Notes, and Assistance; Basic Heating and Cooling Operation; Wiring Diagram Notes and Interpretation; Technical Assistance Information

BASIC HEATING AND COOLING OPERATION:
Basic operation of your heating or cooling system can be obtained by selecting HEAT or COOL on the
System Mode switch, and using UP or DOWN to adjust the temperature. To maintain a single fixed
temperature, you can use the HOLD button. If there Is a padlock present on the display screen, the
keypad lockout feature is enabled (both of the mode slide switches are still functional).
WIRING DIAGRAM NOTES:
1) If the wiring diagrams do not clearly represent or match your system, please refer to "TECHNICAL
ASSISTANCE" below, and contact us before removing any of your existing thermostat wires.
2) All of the DASHED wires shown in the wiring diagrams are either optional, or their usage depends
upon your specific system type (EXAMPLE: Diagram #1 shows the fan wire as optional. This does not
infer that your system does not have a fan, only that there may not be a wire for it).
3) The terminal letters shown in black represent typical wiring usage. The terminal letters shown in
gray represent other possible wiring letter designations that you might see on your particular brand
and mode! of thermostat.
4) If your old thermostat has BOTH an “0" wire and a “B” wire present, then “B" is likely a System
Common (power wire) and can either be connected to the “C" terminal, or taped off and unused.
Connecting a System Common wire to this thermostat’s "B/0" terminal will damage the thermostat,
and also your heating and cooling system equipment.
5) If your existing thermostat connections contain a wire labeled as ‘‘W2", "AUX", “E", or “X2”, this
would indicate that you have additional heating stages present. This is a single-stage thermostat,
and cannot accomodate any of these system components. You will need to select a different model.
6) If replacing an old thermostat that has a mechanical time clock on the front panel, there may be TWO
wires labeled as "C” for the clock power. Do not connect either of them to this thermostat.
