Note: IF YOU DO NOT HAVE AN iOS OR ANDROID DEVICE, PLEASE VISIT LUXGEO.COM.
Step 2: Switch power off
IMPORTANT: Turn off the power at circuit breaker to both your heating & cooling systems before performing any wiring.
Step 3: Remove existing thermostat & install GEO®
- Remove front of existing thermostat from base
- Photograph current wiring for reference
- Release wires and mounting screws 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)
Note: WATCH OUR VIDEO DEMO LUXGEO.COM
Step 4: Powering & wiring LUX/GEO®
GEO® 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 GEO® (adapter & cord not included; recommend 1A adapter) Step 5 provides detail on 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
Wiring Terminal Reference:
Conventional Furnace – gas/oil/electric & air-conditioning 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 wire color used]
(typical)
- 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
- B = Heat Mode Damper
- O = Cool Mode Damper
- W2 = 2nd Stage Heat
- Y2 = 2nd Stage Cool
IMPORTANT: If you have both an RC and RH wire present then remove the RED RC-RH shorting cap found on inside front of GEOTM.
Wiring is complete – you may return “cover” between terminal blocks.
AS AN ADDED RESOURCE, A GLOSSARY OF TERMS IS AVAILABLE ON LUX-GEO.COM
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 property without controlled heating or cooling. Reliance on battery power is not recommended with prolonged absence from property.
- After installation you can choose to set the energy profile” for your GEO® This energy profile will determine the delay in GEO® responding to changes from the App.
- GEO® should only be used with lithium batteries.
Not For Use On:
- 120/240 VAC linevoltage systems (without a transformer)
- Heat pumps that have (Y2) two compressor stages
FOR A DETAILED WIRING GUIDE VISIT LUX-GEO.COM.
Wiring Terminal Reference: Heat Pump Systems
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.
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 ie: Rheem/Ruud/Bard systems) installation]
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
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.
Step 5: Power on
- For C-terminal: secure GEO® front onto base
- For battery power: insert 2-AA lithium batteries & secure GEO® front onto base
- For USB power: place a flathead screwdriver against port cover from inside GEO® along bottom side – twist & push out. Plug in Micro USB and insert into base.
- Once GEO® front has been secured to base (line up and firmly push), return power to system.
WITH GEO SECURE & POWER ON – THE DISPLAY SHOULD ILLUMINATE, IF NOT, CHECK POWER IS BACK ON.
Step 6: Configure system settings
GEO® will guide you through setup Rotate the control wheel to navigate through options and values. To make a selection, press
; to go back, press
. GEO® 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.
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.
Step 7:
If you have not yet downloaded your LUX/GEO® App–do so now
Step 8: Connecting LUX/GEO®
The recommended set-up of GEO® requires an iOS or Android device…using another?… Visit LUXGEO.com. Set-up follows a series of screen prompts – have your GEO® and mobile device ready.
8a. 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.
8b. Connecting GEOTM to your mobile device
Open App and click + icon to add device. When prompted, leaveApp & go to your mobile device’s WiFi settings menu.
Select the WiFi network that looks like TSTAT-xx-xx. Enter in the password displayed on the thermostat. After connecting to TSTAT-xx-xx return back to App.
8c. Select your home WiFi network & enter password
Once the GEO® connects to your home WiFi Network, the thermostat will automatically complete steps 3-6.
8d. When room temp appears on GEO® 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.
Step 9: 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.
Step 10:
Enjoy the comfort, peace of mind, and flexibility of your LUX/GEOTM thermostat.
