Mounting
Typically, the VAV VV550 Controller is factory installed. However, the VAV VV550 Controller is
available with retrofit kits, in which case it must be field installed, and it's named VV551.
Tracer Summit and VV550 Communications Link Wiring
Use 22 AWG Level 4 unshielded communication wire for most Comm5 installations. Limit Comm5
links to 4,500 ft and 60 devices maximum (without a repeater). Use one repeater for an additional
4,500 ft, 60 devices, and 8 communication stubs. Refer to Chapters 2 and 3 for further information
about wire selection.
