7. Troubleshooting

If you encounter issues with your Pearl Thermostat, refer to the following common troubleshooting steps:

• No Display/Power: Check if the AA batteries are correctly installed and fully charged. Ensure power to the HVAC system is on at the circuit breaker.
• HVAC System Not Responding: Verify that the wiring connections to the backplate are secure. Confirm the thermostat is in the correct operating mode (Heat/Cool/Auto).
• Connectivity Issues (ZigBee): Ensure your smart home hub is powered on and within range. Refer to your smart home hub's instructions for device pairing. You may need to initiate a re-pairing process.
• Incorrect Temperature Readings: Ensure the thermostat is not exposed to direct sunlight, drafts, or heat sources that could affect its internal sensor.
• Thermostat Not Responding to Touch: Gently clean the screen surface. If the issue persists, try removing the thermostat from its backplate, waiting 30 seconds, and reattaching it to perform a soft reset.
