General Information
VV550 Enhancements
Controller Interface Flexibility
VV550 controller allows VAV units to communicate on a Trane Comm5 or LonTalk. This controller
works in standalone mode, peer-to-peer with one or more other units, or when connected to a Trane
Tracer Summit or a 3rd party building automation system that supports LonTalk.
Manual Test Function
The VV550 controller includes a manual test button that allows the field technician to manually
exercise the outputs of the controller. This feature is simple enough for the electrician to use to
check valve operation. Though this feature is standard on other Comm5 controllers, the feature is
not available on the VAV VV550 Controller.
Flow Tracking
The VV550 controller has been designed with the ability to be applied in flow tracking applications.
This allows the controller to pair with one of its peers to mirror the flow if that lead box, with or
without an offset (positive or negative static pressure as desired).
Ventilation Flow Control w/ Tempering
The VV550 controller has been designed with the ability to be applied in ventilation flow control
applications. These applications pair a fresh air unit with ventilation boxes to provide fresh
(tempered) air to a floor/area. This feature also includes a freeze protection sequence to protect the
hot water reheat coil from low supply air temperatures.
Auto-commissioning Sequence
The VV550 controller has been 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 and after the action. This allows the installer to more easily checkout the
operation of the box and commission by exception.
Automatic Calibration
The VV550 controller has been designed to automatically calibrate the flow transducer each time
the box transitions to unoccupied. This eliminates the need to initiate/schedule calibration for most
installations. The exception is 24/7 sites, in which case Tracer Summit can be used to initiate/
schedule calibration.
Temporary Heat (Construction Mode)
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. Of course,
the box will only provide heat if hot air is being provided by the air-handling unit.
Local versus Remote Reheat Flexibility
The controller can be configured to have local and/or remote heat. Plus, configuration flexibility is
offered that allows the installer to select whether local or remote heat has priority.
Zone Sensor Air Balancing
When applied with a Trane zone sensor module that includes a setpoint thumbwheel and ON and
CANCEL buttons, the controller offers a zone sensor air-balancing feature. This feature allows the
balancing contractor to drive the box to either its minimum or maximum flow setting by turning
the setpoint thumbwheel on the zone sensor module. Then, the balancing contractor can calibrate
the flow reading by pressing the ON (adjusts the reading upwards) or CANCEL (adjusts the reading
downwards) buttons on the zone sensor module.
