air temperature difference
Only when Air-side difference pressure sensor type is set to 0~50Pa 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 can not be set to No or 0~500Pa.
When Indoor fan control type is not set to Pressure diff ctrl, Air-side difference
pressure sensor type can not be set to 0~500Pa.
