3.4 Easy installation and service
3.4.1 Compact design for effective use of space
3.4.2 Integrated design
Comparing with combination units, the individual units needs no complicated piping and wiring in
the jobsite. It eliminates the communication wire, power wire, oil balance pipe, and refrigerant
distributors between units. Lessing brazing joint can optimize the installation quality and eliminated
the possibility of moisture to get into the system.
3.4.3 Simple signal line connection
Installation is easier as communication wiring can be shared by indoor & outdoor units. It’s easy for the user to
retrofit the existing system with a centralized control by simply connecting to the outdoor units.
PQE & XYE: only one set of PQE communication wires can achieve communication among indoor units,
outdoor units and the network.
Reversible communication, central controller can be connected from indoor side or outdoor side.
