Step 2 Connect the longer PU hose to the port without the Lo(-) silk screen under the
dierential pressure sensor, and route the hose through the top of the cabinet to
the supply air pipe plenum chamber. (There should be two binding points adjacent
to the pressure inlet. The distance between the binding point closer to the
pressure inlet and the pressure inlet should not exceed 25 mm, and the distance
between two binding points is within 20–30 mm.)
Step 3 Connect the cables of the
dierential pressure sensor to the 4, 5, and 6 of x502
terminal.
Step 4 After powering on the NetCol8000, choose Settings > System Settings > Indoor
Fan, and set Air-side
dierence pressure sensor type to 0–500Pa.
