Connecting to Tracer Summit
™
Packaged fresh air units can operate with
Trane building automation software,
Tracer Summit version 14.0 or later.
Note: Tape the non-insulated end of the
shield on shielded wire at the unit. Any
connection between the shield and
ground will cause a malfunction. If daisy-
chained in the unit, splice and tape the
shields to prevent contact with ground.
Communication Wiring
Note: Communication link wiring is a
shielded, twisted pair of wire and must
comply with applicable electrical codes.
An optional communication link provides
a serial communication interface (SCI)
between Tracer Summit
and each Fresh
Air unit (FAU) in the system. The FAU
system can have a maximum of 12 FAUs
per connection link to Tracer Summit. Use
a single 18 AWG shielded, twisted pair
wire with stranded, thinned copper
conductors to establish each
communication link between Tracer
Summit and each unit.
