Troubleshooting Common Issues with Your Honeywell T5+ Smart Thermostat

Wi-Fi Connectivity Problems

Issue: Thermostat won't connect to Wi-Fi or frequently disconnects.

Solution: Verify your router is 802.11 b/g/n compatible and broadcasting at 2.4 GHz.[1] Move the thermostat closer to the router to improve signal strength. Restart your Wi-Fi router and the thermostat by removing power for 30 seconds. Ensure your mobile device is connected to the same Wi-Fi network. If problems persist, reset the thermostat to factory settings and reconnect.

Geofencing Feature Not Working

Issue: Location-based temperature adjustments aren't activating as expected.

Solution: Confirm that location services are enabled on your smartphone and the Honeywell Home app has permission to access your location. Ensure Bluetooth is activated on your device. Check that geofencing is enabled in the app settings. Allow the thermostat 24-48 hours to learn your location patterns before expecting full functionality.

Touchscreen Display Issues

Issue: Screen is dim, unresponsive, or displaying error messages.

Solution: Clean the touchscreen with a soft, dry cloth to remove dust or fingerprints affecting responsiveness. Check system alerts for battery replacement or internal sensor failure messages.[3] If the display remains unresponsive, power cycle the thermostat. For persistent errors, consult the error code documentation or contact Honeywell customer support.

Temperature Not Reaching Desired Settings

Issue: Your home isn't heating or cooling to your programmed temperature.

Solution: Verify your system is compatible with the thermostat (check heating/cooling system type).[1] Confirm your HVAC system is functioning properly by testing manually. Check that Smart Response isn't conflicting with your settings. Ensure auxiliary heat (if applicable) is properly configured for heat pump systems.[2] Review your scheduling to confirm the thermostat isn't in Away mode. Consider that extreme outdoor temperatures may require longer adjustment times.

Filter Change Reminders Not Appearing

Issue: Smart alerts for filter maintenance aren't displaying.

Solution: Ensure push notifications are enabled in your Honeywell Home app settings on your mobile device. Verify your phone has adequate battery and network connectivity. Check that you've properly set up filter change reminders during initial thermostat configuration. Manually reset the filter counter in the app's maintenance section.

Preventive Maintenance Tips

Clean the touchscreen monthly to maintain responsiveness and visibility[8]
Check Wi-Fi connection strength quarterly to prevent connectivity issues
Review and update your temperature schedules seasonally for optimal efficiency
Monitor filter change reminders and replace filters according to manufacturer recommendations
Keep your mobile app and thermostat firmware updated for best performance
