Step 1.1: Download the LUX Products App to your mobile device and create an account.
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.
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.
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.
