Controls Interface
• Zone setpoint
• Current zone temperature
• Fan mode selection (off-auto-high-low)
For optimal system performance, blower coil units can operate as part of an Integrated Comfort™
System (ICS) building automation system controlled by Tracer Summit®. The controller is linked
directly to the Summit control panel via a twisted pair communication wire, requiring no additional
interface device (i.e., a command unit). The Trane ICS system can monitor or override ZN520
control points. This includes such points as temperature and output positions.
Rover Service Software
This windows-based software package option allows field service personnel to easily monitor,
save, download, and configure Tracer™ controllers through a communication link from a portable
computer. When connected to the communication link, Rover™ can view any Tracer controller that
is on the same communication link.
