3.1 Manual Temperature Adjustment

The Google Nest Learning Thermostat is compatible with Alexa. To enable voice control, ensure your Nest account is linked to your Alexa app. Once linked, you can use simple voice commands to adjust your home's temperature. For example, say "Alexa, set the thermostat to 22 degrees Celsius" or "Alexa, turn up the heat."

4. Maintenance

To ensure optimal performance and longevity of your Nest Thermostat, follow these maintenance guidelines:

• Cleaning: Gently wipe the display and outer ring with a soft, dry cloth. Avoid using abrasive cleaners or solvents, as they may damage the finish.
• Software Updates: The Nest Thermostat automatically downloads and installs software updates when connected to Wi-Fi. Ensure your thermostat remains connected to receive the latest features and improvements.
• Battery: The thermostat is primarily powered by your HVAC system, but it also contains a small rechargeable battery. If the battery level is low, the thermostat will indicate this on the display and in the app. Ensure proper wiring to allow the battery to charge.
• Sensor Window: Keep the sensor window (located at the bottom of the display) clear of dust and obstructions to ensure accurate temperature, humidity, light, and activity readings.

5. Troubleshooting

If you encounter issues with your Nest Learning Thermostat, consider the following common troubleshooting steps:

• No Power/Display Off: Check the circuit breaker for your HVAC system. Ensure the thermostat is properly seated on its base and that the wiring connections are secure.
• Wi-Fi Connectivity Issues: Verify your home Wi-Fi network is active. Restart your Wi-Fi router. In the Nest app, check the network settings and attempt to reconnect.
• Incorrect Temperature Readings: Ensure the sensor window is clean and unobstructed. Avoid placing the thermostat in direct sunlight or near heat sources that could affect readings.
• Heating/Cooling Not Activating: Check the mode selected on the thermostat or in the app (Heat, Cool, Eco). Verify that your HVAC system is functioning correctly.
• Schedule Not Working: Review your schedule in the Nest app to ensure it is set as desired. The Auto-Schedule feature may override manual adjustments if it detects a consistent pattern.
