6. Operating Instructions

The PSM40SA thermostat offers simple, manual control over your heating and cooling system.

• System Mode Switch: Locate the system mode switch (typically labeled HEAT, OFF, COOL). Slide the switch to your desired operating mode:
• HEAT: Activates the heating system when the room temperature falls below the setpoint.
• OFF: Turns off both heating and cooling systems.
• COOL: Activates the cooling system when the room temperature rises above the setpoint.
• Temperature Adjustment: Use the temperature slider on the front of the thermostat to set your desired room temperature. Slide the indicator to the desired temperature setting (e.g., 70°F). The system will then work to maintain this temperature.
• Fan Operation (if applicable): Some installations may include a separate fan switch (AUTO/ON).
• AUTO: The fan runs only when the heating or cooling system is actively operating.
• ON: The fan runs continuously, regardless of whether the heating or cooling system is active.

7. Maintenance

Your LUXPRO PSM40SA thermostat requires minimal maintenance to ensure continued reliable operation.

• Cleaning: Periodically wipe the exterior of the thermostat with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the finish or internal components.
• Battery Replacement: As the thermostat is battery-powered, replace the batteries annually or when the low battery indicator (if present) appears. Always use fresh, high-quality alkaline batteries.

8. Troubleshooting

If you experience issues with your thermostat, refer to the following common troubleshooting steps:

• No Power/System Not Responding:
  • Check if the power to your HVAC system is ON at the circuit breaker.
  • Ensure batteries are correctly installed and have sufficient charge. Replace if necessary.
  • Verify all wiring connections are secure at the thermostat and the HVAC system.
• Incorrect Temperature Reading:
  • Ensure the thermostat is not exposed to direct sunlight, drafts, or heat sources (e.g., lamps, appliances) that could affect its temperature sensor.
• System Runs Continuously or Not at All:
  • Confirm the system mode switch (HEAT/OFF/COOL) is set correctly.
  • Adjust the temperature setpoint to be above (for cooling) or below (for heating) the current room temperature to trigger the system.
  • Check the adjustable heat anticipator setting (if applicable and accessible) to ensure it is calibrated correctly for your system.

If problems persist after attempting these steps, contact a qualified HVAC technician or LUX customer support.
