Only when Direct free-cooling is set to No, Motorized damper can be set to
Enable.
Only when Motorized damper is set to Disable, Direct free-cooling can be
set to Disable or Enable.
Only when Air-side difference pressure sensor type is set to 0~500Pa or
Differential pressure sharing is enabled, Indoor fan control type can be set
to Pressure diff ctrl.
When Indoor fan control type is set to Pressure diff ctrl, Air-side difference
pressure sensor type cannot be set to No or 0~50Pa.
When Indoor fan control type is not set to Pressure diff ctrl, Air-side
difference pressure sensor type cannot be set to 0~50Pa.
