INSTALLATION

1. Step 1.1: Download the LUX Products App to your mobile device and create an account.
   
2. Step 1.2: Now set your phone aside and turn off the power at the circuit breaker to both your heating and cooling systems before performing any wiring.
3. Step 1.3: Confirm that your heating and cooling system is powered down by changing the temperature on your thermostat.
   
   Hint: Your system should not make any noise and you should not feel any air exiting your vents.
4. Step 1.4: Remove the front of your old thermostat from its base. If you see thick black wires, wire nuts, or any labels that say 120-240VAC or High Voltage, your system is not compatible with CS1. Please call LUX Technical Support at 856.234.8803 before proceeding with your installation. If you do not see any high-voltage labels or wires, you can continue with your installation.
   
5. Step 1.5: Use the included wire labels to mark which wire is connected to each terminal in your old thermostat.
   Take a picture of your current wiring layout, you will need this picture later.
   
6. Step 1.6: Confirm that you have a C-Wire. If you do, please turn to the next page. If you do not, please skip ahead to page 10.

Installing with a C-wire

Before starting
Turn off the power at the circuit breaker to both your heating and cooling systems before performing any wiring.

1. Step 2.1: Identify your system configuration (see wiring diagrams in appendix). Potential configurations include:
   • Conventional 1H/1C (Y, G, W, R, C)
   • Conventional 2H/1C (Y, G, W, W2, R, C)
   • Heat Pump Single-Stage (Y, G, R, O/B, C)
   • Heat Pump with auxiliary heat or dual fuel (Y, G, R, O/B, W, C)
     If you have only one R wire, please use the RH terminal. If you have a different configuration other than what is listed above, please call LUX Technical Support for help with your installation.
2. Step 2.2: Remove each wire from its terminal – make sure that they don’t fall down back into the wall.
3. Step 2.3: Remove the mounting screws from the base of the old thermostat. Remove the base from the wall.
4. Step 2.4: If you would like to use the trim plate or wall anchors, you can install them now.
5. Step 2.5: Separate CS1 from its base, pull the halves apart from the bottom edge. Pull the wires from your wall through the center hole of the CS1 base. Secure the base to the wall using the included mounting hardware.
   Option 1 – Conventional (furnace) Systems:
6. Step 2.6(f): Following the terminal labels marked “Conventional” on the thermostat base, loosen the screw and insert each labeled wire into the top hole of the corresponding terminal, tighten the screw.
7. Step 2.7(f): If you have both an RC and RH wire present, then remove the red cap located on the left side of the terminal pins. You can now skip ahead to step 2.8.
   Option 2 – Heat Pump Systems:
8. Step 2.6(hp): Following the terminal labels marked “Heat Pump” on the thermostat base and referencing your wiring photo, loosen the screw and insert each labeled wire into the top hole of the corresponding terminal, tighten the screw.
   If your old thermostat did not have a W1 wire but did have a W2 wire, please insert the W2 wire into the W1 terminal.
9. Step 2.7(hp): If you have both an O wire and a B wire (i.e. in some systems), please install the B wire to the “C” terminal.
   For more detailed directions, please see the wiring diagrams in the appendix or call LUX Technical Support.
10. Step 2.8: Securely fasten CS1 onto its base. Once it has clicked into place, return power to your heating and cooling system.
11. Step 2.9: After your thermostat powers up, you are ready to configure CS1 for your heating and cooling system and connect to a wireless network.
    Please skip ahead to the “System Setup” section of this manual on page 18.

Installing without a C-Wire  Using the LUX Power Wire (included)

For installation without C-wire, you will need to access your furnace.
NOTE: DO NOT USE P-WIRE IF YOU HAVE AN ELECTRIC FURNACE OR HEAT PUMP

Before starting
Turn off the power at the circuit breaker to both your heating and cooling systems before performing any wiring.

4. Step 3.4: If you would like to use the trim plate or wall anchors, you can install them now.
5. Step 3.5: Separate CS1 from its base, pull the halves apart from the bottom edge. Pull the wires from your wall through the center hole of the CS1 base. Secure the base to the wall using the included mounting hardware.
6. Step 3.6: Following the terminal labels marked “Conventional” on the thermostat base, loosen the screw and insert each labeled wire into the top hole of the corresponding terminal.
7. Step 3.7: Securely fasten CS1 onto its base
8. Step 3.8: Go to your furnace – remove the door or panel and locate your control board or transformer. In most cases, there should be four wires running from the furnace to your thermostat – Y, G, W, and R. If you have additional wires, leave them as is.
9. Step 3.9:
   • Remove the G Wire from the Fan Terminal at your furnace, insert the wire into your Furnace Transformer Terminal
   • Insert one end of the LUX Power Wire into the now emty Fan Terminal and the other end into the Cool Terminal (with the Y Wire).
10. Step 3.10: If you had to remove a panel or door to access your control panel, replace it now.
11. Step 3.11: Return power to your heating and cooling system. If your system, including your thermostat, does not power up please call LUX Technical Support.
    After CS1 powers up, you are ready to configure it for your heating and cooling system (page 21).
