Shipping And Storage; Uc400 Features - Trane Tracer Uc

Overview

Shipping and Storage

Each VAV order ships with service literature. When unpacking, ensure that the literature is not lost
or discarded with the packing material.
Important: Visually inspect the individual components for obvious defects or damage. All
If storing any component of the VAV system and/or field installed accessories for a period of time
prior to installation, those components must be protected from the elements. Refer to
"Specifications and Dimensions, " p. 7
ranges.
Important: The warranty will not cover damage to the VAV or controls due to negligence during

provides information about the features of the UC400 controller.
Description
The UC400 controller allows VAV units to communicate on a BACnet MS/TP link and is compatible with the latest generation of Trane
controls. This controller can operate in standalone mode, peer-to-peer with one or more other units, or when connected to a Tracer
SC or a 3rd party building automation system that supports BACnet.
The UC400 controller is designed with the ability to be applied in flow tracking applications. This allows the controller to be paired
with one of its peers to mirror the flow of the lead unit, with or without an offset (positive or negative static pressure as desired).
The UC400 controller is designed with the ability to be applied in ventilation flow control applications. These applications combine
a fresh air unit with ventilation boxes to provide fresh (tempered) air to a zone. This feature also includes a freeze protection sequence
to protect the hot water reheat coil from low supply air temperatures.
The UC400 controller is designed with an auto-commissioning sequence. With a discharge air temperature sensor, this feature
exercises the air valve, fan, and heat in the box and records the temperature before/after the action. This allows the installer to easily
verify the operation of the unit and commission by exception. An auto-commissioning report can be generated with Tracer TU service
tool.
The UC400 controller is designed to automatically calibrate the flow transducer each time the unit transitions to unoccupied. This
eliminates the need to initiate/schedule calibration for most installations. The exception is 24/7 sites, in which case, Tracer SC can
be used to initiate/schedule calibration.
Upon reset (and power-up), if the controller does not detect a valid space temperature, the controller will provide temporary heat
by driving the air valve to the heating maximum position.
Note: The unit will provide heat only if the air handler unit provides hot air.
The controller can be configured to have local and/or remote heat. In addition, provided configuration flexibility allows the installer
to select priority for either local or remote heat has.
The UC400 controller has spare I/Os that are not used by the VAV applications. These spare I/Os can be programmed using the Tracer
Graphical Programming editor (by means of the Tracer TU service tool) to measure and/or control ancillary devices such exhaust fans,
second air valve for dual duct VAV, or sensing relative humidity.
The UC400 controller connectors are 2-part connectors with 5.08 millimeter pin separation. The headers are attached on the Tracer
UC400 controller itself. The other portion of the connector is either a screw terminal (for field wiring) or a terminal housing (for factory
wiring). Spare screw terminals come factory installed for field mounted wired zone sensors and common accessories.
The UC400 controller is compatible with the latest wireless zone sensors available from Trane. Wireless zone sensors provide flexibility
of sensor location and re-location as well as reducing the cost of installation. Wireless zone sensor receivers are available as a factory
or field installed option.
The UC400 controller has been designed with flash memory. This allows the option of upgrading the application code in the field
without changing out the controller.
When applied with a Trane zone sensor module, that includes a thumbwheel setpoint or a LCD display, the UC400 controller can easily
be overridden to minimum and maximum flow. By simply turning the thumbwheel to * or increasing the setpoint to maximum on
display sensors (end of range in one direction), the controller drives the air valve to the minimum flow setpoint. Likewise, turning
the thumbwheel to the ** or decreasing the setpoint to minimum on display sensors (end of range in the other direction) the controller
drives the air valve to the maximum flow setpoint. This feature can be disabled by putting Airflow Override Local, Multistate Input
2, and Out of Service using Tracer TU.
Tracer SC and Tracer TU both include auto-commissioning reports that extracts and formats the commissioning data for each VAV
controller. This commissioning report is valuable both for the installer and for the owner. The feature enables the system to be
commissioned by exception, providing a benefit for the installer. The feature also can be used as validation that provides value to
the owner.
Tracer SC includes a new VAV Air System (VAS) specifically designed for both BACnet and LonTalk® VAV controllers. This new VAS
is designed for easy setup.
