Getting started
Locate and gather the following items for ease of installation
Included:
Items needed:
Download the App and Create Your Account
Download your LUX/GEO App
Depending on device type, search the App store for “LUX GEO” and create your LUX/GEOTM user account
IF YOU DO NOT HAVE AN iOS OR ANDROID DEVICE, PLEASE VISIT LUX-GEO.COM.
Switch power off
IMPORTANT: Turn off the power of a circuit breaker to both your heating & cooling systems before performing any wiring.
Remove the existing thermostat & install GEOTM
- Remove the front of the existing thermostat from base
- Photograph current wiring for reference
- Release wires and mounting screws and remove the base from the wall
- Open GEO™ from the base, pull up on plastic “cover” between terminal blocks to access, and pull wires through.
- Secure GEO base to the wall (mounting hardware & optional wall plate included)
Powering & wiring LUX/GEOTM
GEOTM needs only 1 of 3 power source options:
- C-terminal (Recommended & for optimal performance.
Reference photo from step 3 to confirm C-wire.) - Battery* (2-AA Lithium included)
- USB micro-port available on GEOTM
(adapter & cord not included; recommend 1A adapter)
Step 5 provides detail on the battery & USB connection
NOTE: System compatibility
For Use On:
- Most 24-volt heating and cooling systems
- 1 or 2 stage heat / 1 or 2 stage cool: gas, oil, or electric furnace and a/c systems
- 1 or 2-stage heat / 1-stage cool: heat-pump style systems
- 2-wire hydronic (hot water) zone valves
- Gas Millivolt wall/floor heaters
Notice for battery installations:
- Batteries should be replaced at least once per year, but depending on your settings may need to be replaced sooner.
- Battery failure could leave the property without controlled heating or cooling. Reliance on battery power is not recommended with prolonged absence from the property.
- After installation, you can choose to set the “energy profile” for your GEOTM This energy profile will determine the delay in GEOTM responding to changes from the App.
- GEOTM should only be used with lithium batteries.
Not For Use On:
- 120/240 VAC line voltage systems (without a transformer)
- Heat pumps that have (Y2) two compressor stages
Wiring Terminal Reference: Conventional Furnace – gas/oil/electric & air-conditioning*
FOR A DETAILED WIRING GUIDE VISIT LUX-GEO.COM.
for heat pump systems – see section 4.2
Referencing your wiring photo & terminal guide below, wire to GEO.
GAS / OIL / ELECTRIC FURNACE and/or AIR CONDITIONING (typical)
RH (or R) = 24(+) VAC Power, Heat
W1 = 1st Stage Heat
G = Blower Fan
C = 24(-) VAC Common
Y1 = 1st Stage Cool
(other)
RC = 24(+) VAC Power, Cool
B = Heat Mode Damper
O =Cool Mode Damper
W2 = 2nd Stage Heat
Y2 = 2nd Stage Cool
[typical wire color used]
[RED]
[WHITE]
[GREEN]
[BLUE]
[YELLOW]
IMPORTANT: If you have both an RC and RH wire present then remove the RED RC-RH shorting cap found on the inside front of GEOTM.
- Wiring is complete – you may return “cover” between terminal blocks.
Wiring Terminal Reference: Heat Pump Systems
Referencing your wiring photo, attach your thermostat wires to the LUX/GEOTM using your original wiring letters and the following terminal reference as a guide based upon your system type.
HEAT-PUMP (COMPRESSOR) STYLE HEAT/COOL SYSTEM
R (or RC/RH) = 24(+) VAC Power, Cool
O = Reversing Valve
Y1 = Heat Pump Outdoor Unit
G = Blower Fan
W2 = Auxiliary/Emergency Heat
C = 24(-) VAC Common
B** = Reversing Valve (only if no “O” wire- ie: Rheem/Ruud/Bard systems)
[typical wire color used][RED]
[ORANGE]
[YELLOW]
[GREEN]
[WHITE]
[BLUE]
[can vary per each installation]
Note: There should NOT be a wire used on the W1 wire connection at the terminal.
** IMPORTANT: If you have both an O wire and B wire (ie: Trane system), please install B to the “C” terminal
Heat Pump systems (Y1/W1) – YELLOW cap MUST BE MOVED to sit on both pins.
- Wiring is complete – you may return “cover” between terminal blocks.
Power on
- For C-terminal: secure GEOTM front onto the base
- For battery power: insert 2-AA lithium batteries & secure the GEOTM front onto base
- For USB power: place a flathead screwdriver against the port cover from inside GEOTM along bottom side – twist & push out. Plug in Micro USB and insert into base.
- Once the GEOTM front has been secured to base (line up and firmly push), return power to system.
Configure system settings
GEOTM will guide you through setup Rotate the control wheel to navigate through options and values. To make a selection, press
; to go back, press
.
GEOTM will prompt you to select:
- Whether heating and/or cooling are connected.
- System type (only applies if you have heat). Note if you wired per section 4.1 you have a furnace. If you wired per section 4.2 you have a heat pump. If furnace fan is not operating properly after installation, change from furnace: gas to furnace: electric in the settings menu.
- The number of stages for heat/cool you have. The most common is 1 heat/1 cool. Not sure? refer to our online glossary to learn more.
- If you have set more than 1 stage of heat or cool, the OFFSET setting adjusts the stage-2 cut-in.
If you have not yet downloaded your LUX/GEOTM App–do so now
Connecting LUX/GEOTM
The recommended set-up of GEOTM requires an iOS or Android device…using another?… Visit LUX-GEO.com. Set-up follows a series of screen prompts – have your GEOTM and mobile device ready.
Getting ready to connect
You’ve downloaded the LUX/GEO App, created a user account and now, from your GEO, select “yes” for WiFi setup
GEO will begin scanning – but you can move on to 8b.
Connecting GEOTM to your mobile device
- Your GEO will show: “DISCONNECTED”.
- Open App and click + icon to add device. When prompted, leave App & go to your mobile device’s WiFi settings menu.
- Select the WiFi network that looks like LUXGEO-xx-xx
- After connecting to LUXGEO return back to App
Select your home WiFi network & enter password
When room temp appears on GEOTM display, continue by following prompts on App
Once you see on app and 
on GEO – your system is now successfully connected.
Troubleshoot:
You may need to manually reconnect your phone to your wifi network.
If this is unsuccessful – restart GEO by going to menu/settings/network and pick up App from step 8b.
Custom settings & RadiusTM set-up
RadiusTM is a geofence that allows you to set a geographic “fenced” zone via your mobile device. Using GPS, RadiusTM (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 RadiusTM, 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”
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.
Enjoy the comfort, peace of mind, and flexibility of your LUX/GEOTM thermostat.
