Tracer zone controllers operate as standalone 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 peerto-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

•
