SWITCH POWER OFF AND TAKE PHOTO OF EXISTING WIRING

IMPORTANT: Turn off the power at circuit breaker to both your heating & cooling systems before performing any wiring.

DETERMINE HOW YOUR LUX/GEO WILL BE POWERED

LUX/GEO can be powered by one of four methods (in order of best performance):

Method #1 & #2 (Preferred): 24V System Power “C-wire” (this powers GEO from your heating/cooling equipment and provides the best performance when using WiFi)
Method #3: USB micro-port on GEO (wall adapter & cord not included – use 1A wall adapter)
Method #4: Battery Powered* (2-AA Lithium batteries included)

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.

A Micro-USB kit with extra-long power cable is available from LUX through our http://www.luxproducts.com/ website.
Refer to Step 4.1 for wiring method.

Notice for battery powered installations

GEO 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.

REMOVE EXISTING THERMOSTAT AND WIRE YOUR LUX/GEO

Lux Products GEO-WH Wi-Fi Thermostat (4)

Release wires and mounting screws from old thermostat and remove base from wall.
Open GEO from base, pull up on plastic “cover” between terminal blocks to access and pull wires through.
Secure GEO base to wall (mounting hardware & optional wall plate included)

Lux Products GEO-WH Wi-Fi Thermostat (5)

On the following pages, there are several different methods of wiring the GEO thermostat depending upon system type and the power method selected in Step 3. Follow the scenario most appraise for your system type, and please contact LUX support if there are any questions.

WIRING FOR METHODS: #1 C-WIRE, #3 MICRO-USB, AND #4 BATTERY POWER

A WIRING TERMINAL REFERENCE: CONVENTIONAL FURNACE – GAS/OIL/ELECTRIC & AIR- CONDITIONING (WITHOUT LUX POWER BRIDGE)

Referencing your wiring photo & terminal guide below, wire to GEO.

Lux Products GEO-WH Wi-Fi Thermostat (6)

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.

B 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.

Lux Products GEO-WH Wi-Fi Thermostat (7)

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 (i.e.: Trane system), please install B to the “C” terminal

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

WIRING TERMINAL REFERENCE: INSTALLING GEO WITH THE LUX POWERBRIDGE

The LUX Power Bridge 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.
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.

NOTE: When installing the Power Bridge, press the terminal levers before inserting wires into the holes. Once the wire is fully inserted, gently pull on the wire to confirm that it is securely installed. Press all the way down on the lever to release a wire.

A INSTALLING THE LUX POWER BRIDGE ON CONVENTIONAL SYSTEMS

Lux Products GEO-WH Wi-Fi Thermostat (10)

If your system provides a second stage of heating, you may have a W2 wire. You can leave this wire as-is in your furnace and connect it to the W2 block on your new thermostat.
If you have two R wires (R, Rc, or Rh), please call LUX Technical Support for assistance with your installation.
Connect your old Y wire to the empty hole next to the blue end of the y-splitter (1). Snap the orange lever shut to secure the wire in its place. Insert the yellow end of the y-splitter into the thermostat’s Y terminal and the green wire into the G terminal.
Move your old G wire to the C terminal on your thermostat.

B INSTALLING THE LUX POWER BRIDGE ON HEAT PUMP SYSTEMS

Lux Products GEO-WH Wi-Fi Thermostat (11)

If your system provides a second stage of heating, you may have a W2 wire. You can leave this wire as-is in your furnace and connect it to the W2 block on your new thermostat.
You may or may not have a W1 terminal block on your control board. Do not connect the Power Bridge’s “W” wire to any terminal block on your control board.
Connect your old Y wire to the empty hole next to the blue end of the y-splitter (1). Snap the orange lever shut to secure the wire in its place. Insert the yellow end of the y-splitter into the thermostat’s Y terminal and the green wire into the G terminal.
Move your old G wire to the C terminal on your thermostat.

INSTALLING THE LUX POWER BRIDGE ON COOL ONLY SYSTEMS

Lux Products GEO-WH Wi-Fi Thermostat (12)

The Power Bridge’s “W” wire is not used for this system – do not connect it to your control board.
Connect your old Y wire to the empty hole next to the blue end of the y-splitter (1). Snap the orange lever shut to secure the wire in its place. Insert the yellow end of the y-splitter into the thermostat’s Y terminal and the green wire into the G terminal.
Move your old G wire to the C terminal on your thermostat.

INSTALLING THE LUX POWER BRIDGE ON HEAT ONLY SYSTEMS

Lux Products GEO-WH Wi-Fi Thermostat (13)

For this system type, you will need to connect the Power Bridge’s “Y” wire to the W1 terminal block on your control board. Re-label the yellow tab on the Power Bridge’s Y wire with one of the included W wire stickers. You will not use the Power Bridge’s “W” wire for this system.
Connect your old W wire to the empty hole next to the blue end of the y-splitter (1). Snap the orange lever shut to secure the wire in its place. Insert the yellow end of the y-splitter into the thermostat’s W terminal and the green wire into the G terminal.
Move your old G wire to the C terminal on your thermostat.

POWER ON

For methods #1 with C-wire and #2 with LUX Power Bridge: secure GEO front onto base

Custom settings & Radius set-up

Radius is a geofence that allows you to set a geographic “fenced” zone via your mobile device. Using GPS, Radius (geofencing software) will recognize your approach into or out of the “fenced” area and trigger your thermostat to adjust to either your “at home” comfort settings or “Away” settings which provide more efficient energy use. With Radius, geofencing can be set on multiple devices/users and to your custom needs and can work with or without a thermostat schedule to still save energy when away from home.

Please note and be assured that your GPS location is NEVER reported or known by LUX Products.

SETTING YOUR “FENCE”

Lux Products GEO-WH Wi-Fi Thermostat (23)

TIP: If you set your fence further from your home then your system will have more time to make your home comfortable before you get home. If you set the fence closer to home then you will save more energy but sometimes your system will not have time to recover before you get home. If you are using battery power, we recommend setting a larger distance.
