Outdoor unit Refer to "Error code table (Outdoor unit)" on page 03-3
Detective actuator Indoor unit main PCB
1. Detect the open condition of the sensor.
2. When signal from sensor is "L" (0 V) for more than
20 min.
Forecast of cause
Connector connection failure
Sensor failure
Main PCB failure
Check point 1. Check the connector connection and cable open
• Check if connector is loose or removed.
• Check erroneous connection.
• Check if sensor cable is open
→ Reset power when reinstalling due to removed connector or incorrect wiring.
↓
Check point 2. Check the conduction or voltage
• Conduction check (sensor connections error)
Disconnect the sensor and check the 2-3 pin on sensor connector.
→ With conduction: Sensor failure
→ Without conduction: Main PCB failure
• Voltage check (sensor signal error)
Disconnect the sensor and check the voltage of 3 pin of the CN10 on the main PCB.
→ 5 V: Sensor failure
→ Other than 5 V: Main PCB failure
