What does 6-time blink mean?
This fault indicates poor contact in the i-see SENSOR wiring or an error during the loading of its corrected data. The i-see SENSOR is crucial for intelligent detection of room occupants and optimized airflow, so its malfunction can lead to reduced comfort and inefficient energy use. The unit may operate but without smart sensing capabilities.
