Note<br />
1. Sensor checking function is used with Refrigerant<br />
Checking and Refrigerant Au<strong>to</strong> Charging.<br />
2. Check abnormal sensor<br />
3. It is displayed at the LED on the main PCB at each step.<br />
4. Reference the sensor error in ** page.<br />
5. Refer <strong>to</strong> service manual about refrigerant au<strong>to</strong><br />

Caution<br />
1. Confirm au<strong>to</strong> addressing has been performed (Check<br />
installed number of IDU).<br />
2. The error can be displayed even if the sensor is<br />
normal according <strong>to</strong> installation and temperature<br />
condition. If error occurs, check the sensor and<br />
judge abnormality.<br />
