4. Fan Settings: Select 'AUTO' for the fan to run only when cooling, or 'ON' for continuous fan operation.
5. Heating (if applicable): If an electric heater is installed, set the thermostat to 'HEAT' mode and adjust the desired temperature.

For detailed programming and advanced features, refer to your specific thermostat's instruction manual.

5. Maintenance

Regular maintenance is crucial for the longevity and efficient performance of your EcoTemp AC Package Unit. It is recommended to have the unit inspected and serviced by a qualified HVAC technician annually.

User Maintenance Tasks:

• Air Filter Replacement: Check and replace or clean the air filter monthly, or more frequently if the unit is in constant use or in dusty environments. A dirty filter restricts airflow and reduces efficiency.

6. Troubleshooting

Before contacting a service technician, review the following common issues and potential solutions. For complex problems, always consult a qualified HVAC professional.

Common Issues:

• Unit Not Turning On:
  • Check if the thermostat is set to 'COOL' or 'HEAT' and the desired temperature.
  • Verify the main power disconnect switch is 'ON'.
  • Check for tripped circuit breakers at your electrical panel.
• Insufficient Cooling/Heating:
  • Ensure the air filter is clean and not obstructed.
  • Check that outdoor unit coils are free of debris.
  • Verify all supply and return vents are open and unobstructed.
  • Ensure windows and doors are closed.
• Unusual Noises:
  • Minor operational sounds are normal.
  • Loud or unusual noises (e.g., grinding, squealing) may indicate a mechanical issue requiring professional service.
