Controllers
Tracer® ZN010 controller is a stand-alone microprocessor
controller.
Tracer® ZN510 controller can be used as either a stand-
alone or communicating microprocessor controller.
Tracer® ZN520 Controller
The Tracer® ZN520 controller is a factory-installed, -tested
and -commissioned LonTalk® control designed to provide
control of Trane products. The discrete speed controller
can also be used in a stand-alone application. Features
include:
• Automatic fan-speed reset
• Automatic ventilation reset
• Active dehumidification
• Manual output test
• Filter maintenance
• Master slave
• Water valve override
• Freeze avoidance
• Interoperability
Three generic I/O ports
The Tracer® ZN520 controller is designed to be used in the
following applications:
• As part of a Tracer® SC or Tracer® Summit®
building
automation system (BAS), the Tracer® ZN520
becomes an important part of the Tracer® control
system.
• The Tracer® ZN520 can function as a completely stand-
alone controller in situations where a BAS is not
present.
• For situations when a non-Trane BAS is present, the
Tracer® ZN520 can be used as an inter-operable unit
controller.
