Tracer
®
ZN.520
Overview
The Trane
®
Tracer
®
ZN.520 con-
troller is a factory-installed and
commissioned, direct-digital
controller (DDC) offering for
classroom unit ventilator sys-
tems. (See Figure 1: “Tracer
ZN.520 Control Board”) The Trac-
er ZN.520 can also be applied to
other Trane
®
interoperable HVAC
equipment, including the fan coil
and blower coil products. (For
more information see,Table 1:
Tracer™ ZN.520 Unit Controller
features and coil availability, on
page 8 for more information.) For
more information regarding the
application of the Tracer ZN.520
to other Trane products, contact
the appropriate local Trane sales
office.
Trane offers a complete solution
to space comfort control with the
flexibility of Integrated Comfort
System (ICS) and stand-alone
control packages. The ICS control
package combines HVAC equip-
ment and building management
into one environmental comfort
system.
Integrating the Tracer ZN.520 on
classroom unit ventilators, and
tying them to a Tracer Summit
®
system will provide a complete
building management system.
The stand-alone control package
offers the features and function-
ality of the direct digital control
without a front-end building au-
tomation system, while providing
future considerations for ICS.
Equipment problems can often be
diagnosed on each unit without
having to access the unit compo-
nets. These diagnostics can be re-
ceived remotely via a modem with
a Tracer Summit building automa-
tion system, thus reducing the
number of actual on-site service
calls; through the Rover
®
service
tool connected to a communica-
tion jack located inside the Trace
zone sensor; or connected to the
unit.
The Tracer ZN.520 is factory-
mounted, tested, wired, config-
ured and commissioned for the se-
lected application.
The Tracer ZN.520 configuration
has flexible point and product con-
figurations. For example, with
point configuration, a specific bi-
nary point can be configured to ac-
cept input from either a time clock
or some type of generic device.
