should only be used with lithium batteries.
Battery failure could leave property without controlled heating or cooling. Reliance on battery
power is not recommended with prolonged absence from property.
Battery life will vary depending on your settings. After installation you can choose to adjust the
“energy profile” for your GEO. This energy profile will determine the delay in GEO responding to
changes from the App, but can increase battery life.
Refer to Step 4.1 for wiring method.
Notes for Method #3: Micro-USB
You can use any standard USB wall adapter and Micro-USB cable, however the wall adapter must
be rated for 1 Amp (1000 mA) or higher.

scenario most appriate for your system type, and please
contact LUX support if there are any questions.

HEAT-PUMP (COMPRESSOR) STYLE HEAT/COOL SYSTEM [typical wire color used]
R (or RC/RH) = 24(+) VAC Power, Cool [RED]
O = Reversing Valve [ORANGE]
Y1 = Heat Pump Outdoor Unit [YELLOW]
G = Blower Fan [GREEN]
W2 = Auxiliary/Emergency Heat [WHITE]
C = 24(-) VAC Common [BLUE]
B** = Reversing Valve (only if no “O” wire- [can vary per each installation]
ie: Rheem/Ruud/Bard systems)
Note: There should NOT be a wire used on the W1 wire connection at terminal.
** IMPORTANT: If you have both an O wire and B wire (ie: Trane system), please install B to the “C” terminal
4.1b Wiring Terminal Reference: Heat Pump Systems (without LUX Power Bridge)
Referencing your wiring photo, attach your thermostat wires to the LUX/GEO using your original wiring
letters and the following terminal reference as a guide based upon your system type.
GAS / OIL / ELECTRIC FURNACE and/or AIR CONDITIONING [typical wire color used]
RH (or R) = 24(+) VAC Power, Heat [RED]
W1 = 1st Stage Heat [WHITE]
G = Blower Fan [GREEN]
C = 24(-) VAC Common [BLUE]
Y1 = 1st Stage Cool [YELLOW]
(other)
RC = 24(+) VAC Power, Cool [can vary per each installation]
B = Heat Mode Damper [can vary per each installation]
O = Cool Mode Damper [can vary per each installation]
W2 = 2nd Stage Heat [can vary per each installation]
Y2 = 2nd Stage Cool [can vary per each installation]
IMPORTANT: If you have both an RC and RH wire present, remove the RED shorting cap inside of GEO
(the YELLOW shorting cap must only be on one pin, not both).
Wiring is complete - you may return “cover” between terminal blocks .
Wiring for methods: #1 C-wire, #3 Micro-USB, and #4 Battery Power
4.1a Wiring Terminal Reference: Conventional Furnace - gas/oil/electric & air-
conditioning (without LUX Power Bridge)
Referencing your wiring photo & terminal guide below, wire to GEO.
IMPORTANT: For Heat Pump applications, the YELLOW shorting cap must be across both metal pins
instead of the default of just one. Also, there will NOT be a wire connected to the “W1” terminal.
Wiring is complete - you may return “cover” between terminal blocks .

Wiring for method: #2 using LUX Power Bridge
4.2 Wiring Terminal Reference: Installing GEO with the LUX PowerBridge
The LUX PowerBridge is for applications that do not have a C-wire at the thermostat:
Take a photo of the wiring at both your thermostat and your furnace. The Power Bridge
cannot be used with 2-wire applications, and requires at least cooling or heating wires
and a fan “G” wire at the thermostat. If you have more wires (multi-stage systems) than
are needed for installing the Power Bridge, leave them attached as they are.
AT YOUR THERMOSTAT – Use the thermostat wire labels to identify each thermostat
wire with its current terminal letter. If any of your thermostat wiring connections are
unclear, please call LUX Technical Support.
NOTE: When using the Y-Splitter, pull the orange
lever all the way up before inserting your wire.
Press the lever back down to lock a wire in place.
AT YOUR FURNACE (AIR HANDLER) – Remove the door panel and locate your control
board. Use the additional wire labels to identify each wire from your thermostat with
its terminal letter on the control board. If any of your furnace wiring is unclear, please
call LUX Technical Support. Depending upon your application, some wires attached to
the control board will remain in place and will not be used with the LUX Power Bridge.
