Operating Instructions
Basic Operation
- Adjusting Temperature: Use the up and down arrows on the thermostat's display or within your smart home app to set your desired temperature.

Remote Sensor Usage
The TQX thermostat comes with one remote sensor and can be paired with up to five additional sensors (sold separately). These sensors monitor temperature, humidity, and occupancy to provide whole-house comfort.
- The TQX system adjusts the overall temperature based on combined sensor data from all rooms collectively.
- Each single sensor does not regulate individual rooms independently.
- Place remote sensors in key living areas to optimize comfort where it matters most.

- Battery Replacement: The remote sensor uses 2 CR2 batteries (included). Replace them when the low battery indicator appears in your smart home app or on the thermostat.
- Firmware Updates: Ensure your thermostat's firmware is up to date through your smart home app to benefit from the latest features and improvements.
Troubleshooting
- Thermostat not powering on: Check the circuit breaker for your HVAC system. Verify C-wire connection or proper installation of the Lux Power Bridge.
- Cannot connect to smart home app: Ensure your Matter-enabled smart speaker/hub is online and within range. Re-attempt the Matter pairing process.
- Inaccurate temperature readings: Ensure remote sensors are not placed near heat sources, direct sunlight, or drafts. Verify sensor battery levels.
- HVAC system not responding: Check all wiring connections at the thermostat and the HVAC unit. Ensure the correct system type is configured in the thermostat settings.
