Setup
1. Compatibility Check
Before installation, ensure your HVAC system is compatible with the W200. The thermostat works with approximately 85% of HVAC systems, including furnaces, air conditioners, heat pumps, boilers, and PTAC units. If your system lacks a C-wire, an Aqara C-Wire Adapter (sold separately) is required for stable power.
2. Wiring Installation
Turn off power to your HVAC system at the circuit breaker before beginning installation. Carefully remove your old thermostat and take a picture of the existing wiring for reference. Connect the wires to the corresponding terminals on the Aqara W200. A trim kit is included to cover any old wiring marks.

3. App Pairing and Configuration
After physical installation, download the Aqara Home app. Open the app, tap '+' in the top right, and select 'Add Accessory'. Scan the QR code on the thermostat or select 'Thermostat Hub W200' from the HVAC category. Follow the in-app instructions to pair the device with your network and configure initial settings.

Operating Instructions
1. Manual and App Control
Adjust the temperature directly on the 4-inch touchscreen display or remotely via the Aqara Home app. The app provides a comprehensive interface for setting temperatures, scheduling, and monitoring your HVAC system.

2. Voice Assistant Integration
When connected to compatible platforms, control your thermostat using voice commands through Siri, Google Assistant, or Alexa. For example, say "Hey Siri, set the room temperature to 70°F."
3. Apple Adaptive Temperature & Clean Energy Guidance
Leverage Apple Home app features for enhanced energy savings and comfort:
- Adaptive Temperature: Uses your iPhone's location and activity states (home, sleep, away, extended away) to automatically adjust the thermostat, providing comfort upon arrival and saving energy when away. Requires a home hub (Apple TV or HomePod) and an iPhone/Apple Watch running iOS 26 or later.
- Clean Energy Guidance: Makes small temperature adjustments to utilize cleaner grid times, potentially reducing electricity costs and carbon emissions. This feature is available only in the contiguous U.S.

4. Smarter Presence Detection (mmWave Radar)
The built-in mmWave radar detects real human presence, not just motion. This allows the W200 to automatically adjust temperature when you are present and save energy when no one is home. The screen activates instantly upon approach, and the presence sensor can be used in smart automations, such as turning on lights.

5. Smart Display Functions
The W200 can act as a visual control panel for other Aqara devices. It displays visitor snapshots from compatible Aqara video doorbells (G410/G400, G4 excluded) and allows unlocking smart locks with a tap.

Maintenance
To ensure the longevity and optimal performance of your Aqara Smart Thermostat W200, follow these general maintenance guidelines:
- Cleaning: Gently wipe the touchscreen and exterior with a soft, dry, or slightly damp cloth. Avoid using abrasive cleaners, solvents, or aerosol sprays, as these can damage the device.
- Software Updates: Regularly check for and install firmware updates through the Aqara Home app. Updates often include performance improvements, new features, and security enhancements.
- Environmental Conditions: Ensure the thermostat is not exposed to extreme temperatures, direct sunlight, or excessive humidity, which can affect its accuracy and lifespan.
Troubleshooting
If you encounter issues with your Aqara Smart Thermostat W200, refer to the following common troubleshooting steps:
- No Power: Verify that the power to your HVAC system is on at the circuit breaker. Check all wiring connections to ensure they are secure and correctly matched according to the installation guide. If using a C-Wire Adapter, ensure it is properly installed.
- Connectivity Issues: Ensure your Wi-Fi network (2.4 / 5GHz) is active and the thermostat is within range. Restart your Wi-Fi router and the thermostat. If connecting to Matter, ensure your Matter controller is properly set up and the pairing code is correctly entered.
- Inaccurate Temperature Readings: Ensure the thermostat is not installed near heat sources (e.g., direct sunlight, lamps, vents) or drafts that could affect its sensor. If using external temperature sensors, verify their placement and connectivity.
- App Control Not Responding: Check your internet connection and ensure the Aqara Home app is updated to the latest version. Restart the app and try again.
- HVAC System Not Responding: Confirm that the thermostat is set to the correct mode (Heat, Cool, Auto) and the desired temperature is outside the current room temperature. Check your HVAC system for any error codes or issues.
