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

aTracer 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.

Figure 1: Tracer ZN.520 Control Board

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.
