Tracer zone controllers operate as stand-
alone devices or as part of a Trane
Integrated Comfort system (ICS). The
controllers communicate with a Tracer
Summit building automation system via
a LonTalk communication link. LonTalk
allows the controllers to operate in peer-
to-peer configuration and to
communicate with other compatible
building control systems.
Trane offers a variety of wall-mounted
zone sensors for Tracer controllers. Zone
sensors come with any of the following
options:
• Temperature setpoint thumbwheel
• Fan speed switch
•
ON

occupancy buttons
