19.02.02. Indoor EC Fan Speed setting / Commissioning Procedure Via Control Interface
1. Refer to the Fan Performance Data or the Fan Curve specific to your air conditioner.
2. Determine the Required Fan Speed (%) which matches your Airflow and External Static Pressure
requirements using either the Fan Performance Data or the Fan Curve.
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.
3. Use this Required Fan Speed % to set the medium speed via the control interface, following the menu
navigation:
G. Service Gfc. Service Settings Gfc. Thermoregulation Gfc4. Thermoregulat. (Supply Fan
Settings).
