The PU hoses for connecting the differential pressure sensor are ready.
The hoses and cables are bound along the routes.
The pressure tube at the air return side needs to be bound to the top cabinet
beam horizontally. If a blocked damper is configured, route the pressure tube
through the hole reserved in the damper enclosure frame, and bind the
pressure tube to the cable bridge inside the damper enclosure frame.
After powering on the NetCol8000, choose Settings > System Settings >
Common Settings, and set Air-side difference pressure sensor type to
0~500Pa.
