Controls

Unit controlled by BAS

Each unit must be equipped with a TCI-R board. A communication bus (twisted shielded pair) must link each TCI-R to the Trane Roof Top Manager (RTM) or to the communication gateway (in the case of an external BAS). Connect one temperature sensor to each unit. LonTalk® communication interface LTCl-R board allows ICS communication between a ReliaTel™ unit and LonTalk® communication applications.

Unit controlled by Tracker™ supervisor

The units must also be equipped with the TCI-R communication board. One remote sensor is required on each unit for a constant flow volume. In the case of a variable flow installation (VariTrac™) these sensors must not be installed. A twisted shielded pair must be used for the communication link. The main functions of the Tracker™ supervisor are control of setpoints, timetable management (Programming) and display of faults. For more details refer to the supervisor documentation.
