Display shows E19; charger may indicate that maximum current cannot be set or may default to a low current.

Safety first: Turn off power before adjusting internal settings.

• Check configuration switches: Locate the current setting dip switches or selector on the control board. Verify they match the branch circuit rating and Sun Country Highway installation guide.
• Reset to default: If allowed by the manual, reset configuration to factory defaults and reprogram the desired current limit.
• Inspect selector hardware: If a rotary switch or potentiometer is used, ensure it is not broken or loose. Replace if physically damaged.
• Board replacement: If configuration cannot be stored or read correctly, the control board’s memory may be faulty and require replacement.
