If you encounter an error code on your HVAC system, follow these steps:

2. Identify the error code: Locate the error code on the system's display or control panel.

3. Refer to the manufacturer's documentation: Consult the user manual or service guide to determine the cause of the error.

4. Troubleshoot and repair: Follow the troubleshooting steps provided in the documentation to identify and fix the underlying issue.

5. Reset the system: Once the repair is complete, reset the system by turning it off and back on.
