Typical Control Connections
Shown below are typical interfaces between the VLT 6000 and other
components in an HVAC system. The terminal numbers and the
functions of the terminals are identical on all VLT 6000s. An optional
relay card, not shown, can provide four additional Form C output
relays. The RS-485 connections allow direct communication through
