the increase in air temperature as soon as the door is opened.
Press the up button.
1 time = FC sensor temperature. The current FC sensor temperature is displayed in a code form
(refer Section 6.2.3 Sensor Temperature Conversion).
2 times = Defrost sensor temperature. The current defrost sensor temperature is displayed in a code
