General Information
Flash Download
The VAV controller has been designed with flash memory. This allows us the option of upgrading
the controller in the field (features, corrections to defects) without changing out the controller.
Air/Water Balancing Application
An air/water balancing application is available in Rover that simplifies the startup, checkout and
balancing of VAV systems. This application is specifically designed for the balancing contractor.
Service Pin from the Trane Zone Sensor
Several Comm5 installation and commissioning scenarios have the technician pressing the
"service" button on the controller. By doing so, a service pin message is broadcast and received by
either the Rover service tool or by Tracer Summit (depending on the scenario). Because access to
the service button on the controller is often difficult, functionality has been included in the
controller that allows the technician to press and hold the ON button on the zone sensor to replicate
a service button press.
Trane Controller Compatibility
The VV550 is a Comm5 controller. As such, the controller is compatible with the latest generation
of Trane controls. This allows the VV550 controller to exist on the same communication wire as the
rest of our Comm5 controllers and share data with them as required. Additional inputs and outputs
can easily be added to the same communication link (Tracer MP503) for any required auxiliary
functions. In the past the cost of adding additional inputs and outputs (Comm4 link by way of a
UPCM) was much less cost-effective.
Drive Min and Max from Zone Sensor
When applied with a Trane zone sensor module that includes a thumbwheel setpoint, the VV550
controller can easily be overridden to minimum and maximum flow. By simply turning the
thumbwheel to "*" (end of range in one direction) the controller drives the air valve to the minimum
cooling flow setpoint. Similarly, turning the thumbwheel to the and "**" (end of range in the other
direction) the controller drives the air valve to the maximum cooling flow setpoint.
VV550 Features
Auto-commissioning Report (Tracer Summit)
Tracer Summit v15 and greater includes an auto-commissioning report 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 -- a
benefit for the installer. The feature also can be used as validation -- valuable to the owner.
Simpler VAS
Tracer Summit v15 includes a new VAV Air System (VAS) specifically designed for Comm5
controllers. This new VAS was designed to be much simpler to understand and setup compared
to the existing (Comm3/4) VAS.
Static Pressure Optimization
As a part of the standard application, VAS calculates the duct static pressure setpoint based on the
most open VAV box. Until Tracer Summit v15, this feature was provided by way of field custom
programming.
Ventilation Optimization
As a part of the standard application, the VAV system has the ability to calculate the ventilation
setpoint for the air-handling unit. In addition, the VV550 controller has a ventilation ratio limit
feature that automatically increases airflow to maintain the required ventilation while operating
