3.2 High Ceiling operation
Function to Control the Air Volume by Ceiling Height Control of the air intensity has been made possible by employing a
height-control algorithm for the interior fan.
According to the height of the installation, it provides variability of indoor fan motor rpm. If the height of installation is low
then you can adjust low rpm of indoor fan motor. On the other hand if the height of the installation is high you can adjust
high rpm of indoor fan motor. Selection of speed can be done by slide switch at the back of the LCD wired remote.

[ Notes ]
1. To get the desired Airflow & E.S.P. combination from the table set the matching value from the table. Value other than
that in table will not give the combinations of airflow & E.S.P. which are mentioned in the table.
2. Table data is based at 230V. According to the fluctuation of voltage, air flow rate varies.
