Tracer zone controllers, shown in 
Figure 3, can operate on a Tracer 
Summit building automation system, on 
a peer-to-peer network, or as stand-
alone devices.

The Rover service tool can configure the 
controllers through the communication 
jack in a zone sensor or at any accessible 
location on the LonTalk communication 
link.
