Communication Interface
Important! To help ensure optimal
performance of the Rover service
tool, please use the latest version.
To obtain the latest version con-
tact your local Trane sales repre-
sentative or service technician.
Note: Refer to the Tracer system
manuals for more information on
communications.
The Tracer ZN524 communicates via
Comm5 (LonTalk) to a building man-
agement system, the Rover service
tool, and other unit controllers on the
communications link. Each Tracer
ZN524 requires a unique address for
the system to operate properly. Every
Tracer ZN524 has this address (Neuron
ID) embedded in the microprocessor,
which eliminates the need for field-
addressing of the units. Each unit also
ships from the factory with a unit iden-
tification tag. (See “Location Identifier”
on page 23, for more information.)
Building automation system
Trane offers a state-of the art front-end
building automation system designed
to coordinate and monitor Trane equip-
ment and controllers: Tracer Summit.
The Tracer Summit system allows the
user to monitor and/or change Tracer
ZN524:
• status, parameters, sensor data,
diagnostics, and internal variables;
and
• setpoints, operating modes, and out
puts.
Service tool
Trane also offers a service tool to work
in conjunction with the Tracer Summit
system or with peer-to-peer and stand-
alone systems: the Rover service tool.
Communication to the Tracer ZN524, or
multiple controllers, can also be accom-
plished by using the ICS software serv-
ice tool.
A personal computer running Rover
may be directly connected to a stand-
alone Tracer ZN524; connected to the
communications jack in the Trane zone
sensor; or connected to a communicat-
ing unit’s Tracer ZN524
unit controller, to access
all of the units on a com-
municating link.
Rover allows the user to
interface with the Tracer
ZN524, but will not allow
any advanced control
(e.g. equipment schedul-
ing or trending). To pur-
chase a copy of the ICS
software service tool,
contact the BAS depart-
ment at your local Trane
dealer.
Stand-Alone
In a stand-alone configuration, com-
mands for operation are determined
based on input from the zone sensor,
humidity sensor, and field-mounted
timeclock (See Figure 6).
• Timeclock can be wired to the Tracer
ZN524 to index the unit between
occupied and unoccupied modes.
• A unit-mounted, analog, leaving
water temperature sensor is used to
initiate the boilerless control or the
optional waterside economizer
routines.
These sensors are required for proper
system operation and are provided as
standard on stand-alone units.

Interoperability
Trane has lead the industry with
BACnet interoperability and Trane is
now expanding the realm of interopera-
ble solutions by offering LonMark certi-
fied unit controllers. The Tracer ZN524
controller conforms to the LonMark
Space Comfort Controller profile. (See
“Appendix—Data Lists” on page 47, for
more information.) This allows the
ZN524 to be used as a unit controller
on other control systems that support
LonTalk and the SCC profile. Now build-
ing owners have more choices and
design engineers have more flexibility
to meet the challenges of building
automation.
