Typical Control Connections - Trane TR1 6002 Installation And Operation Manual

Typical Control Connections

Shown below are typical interfaces between the TR1 and other
components in an HVAC system. The terminal numbers and the
functions of the terminals are identical on all TR1s. An optional relay
card, not shown, can provide four additional Form C output relays.
The RS-485 connections allow direct communication through the
drive’s built-in serial communication protocols.
