Troubleshooting

If you encounter issues with your ProSelect SL11NP thermostat, consider the following common solutions:

• Display is Blank:
  • Check if the thermostat is receiving power from the hardwired connection.
  • Ensure the backup batteries are correctly installed and not depleted. Replace if necessary.
• Heating/Cooling Not Activating:
  • Verify that the system mode switch is set to HEAT or COOL, not OFF.
  • Check that the set temperature is appropriate for activating the system (e.g., set temperature below room temperature for cooling, above for heating).
  • Ensure the fan mode is set to AUTO or ON.
  • Allow for short cycle protection delay if the system recently turned off.
• Incorrect Temperature Reading:
  • Ensure the thermostat is not exposed to direct sunlight, drafts, or heat sources that could affect its temperature sensor.
  • Verify the Fahrenheit/Celsius switch is set to your desired unit.
• Settings Lost After Power Outage:
  • The thermostat is designed to retain settings in permanent memory. If settings are lost, ensure the backup batteries are functional and properly installed.
