Set proper external static pressure (ESP) according to the actual installation
conditions. Otherwise it may cause some problems.
ESP can be set through the DIP switch SW2 on the main board or the new
wired controller. Please refer to Part “8.3 DIP switch settings on main board”
for SW2 setting or the wired controller manual for wired controller setting.
If the connecting duct is long and the ESP setting is small, the airflow will
be very small, leading to poor performance.
If the connecting duct is short and the ESP setting is large, the airflow will
be very large, leading to higher operating noise and even water may be
blown out through the air outlet.

Four ESP can be set through DIP switch SW2.
Ten ESP can be set through the new wired controller.
