Maintenance

The WarmlyYours nTrust 2.0 thermostat requires minimal maintenance. Keep the screen clean and free from dust and debris. Use a soft, dry cloth for cleaning. Do not use abrasive cleaners or solvents, as these can damage the display and touch interface.

Troubleshooting

If you encounter issues with your nTrust 2.0 thermostat, consider the following common troubleshooting steps:

• No display/power: Check the circuit breaker to ensure power is supplied to the thermostat. Verify all wiring connections are secure.
• Incorrect temperature reading: Ensure the floor sensor is properly installed and connected. Check for any damage to the sensor cable.
• Heating not activating: Verify the desired temperature is set above the current floor temperature. Check the GFCI for tripping.
• GFCI tripping: A tripping GFCI indicates a ground fault. Immediately disconnect power and contact a qualified electrician to diagnose and resolve the issue. Do not attempt to bypass the GFCI.

If problems persist after attempting these steps, contact WarmlyYours technical support for assistance.
