3. Divide the determined % Fan Speed by 10 to get the corresponding voltage to the nearest one decimal
figure.
Example:
Unit Model:
CAY620T / EVY620T
Airflow: 3200 l/s
External Static Press: 100 Pa
Required Fan Speed: 62.9%
LED FAN STATUS Display (Divide Required Fan Speed by 10): 6.2V ( 62.9 / 10);
LED adjustments are in 0.1V increments.
4. Use this calculated fan voltage to set the indoor speed via the CIB01 Fan Control.
