Integration Options (Interfacing with other control systems) - Trane offers the following ways to
interface with other control systems.
1. Use Trane LONMARK
®
, factory-commissioned VAV controllers
2. Use Trane BACnet
®
factory-commissioned VAV controllers.
Factory-installed vs. Factory-commissioned
The terms factory-installed and factory-commissioned are often used interchangeably. Trane takes
great pride in being the industry leader in factory-commissioned DDC controllers. Table , p. 10
differentiates these concepts.
Factory-commissioned controllers provide the highest quality and most reliable units for your VAV
system. Additional testing verifies proper unit operation including occupied/unoccupied airflow,
temperature setpoints, communication link functionality, and output device functionality. The
benefits of factory-commissioning are standard on VariTrane
terminal units with Trane DDC
controls. This means that factory-commissioned quality on VariTrane VAV units is now available
on ANY manufacturer’s control system that can communicate using the LonMark
®
Space Comfort
Control (SCC) protocol or using BACnet
®
communication protocol. (See Controls section for
complete listing of variables which are communicated.)
Pneumatic—Pneumatic controllers provide proven reliability
and performance. A full line of options provide:
Highest quality PVR available, which maximizes space
temperature control.
Pressure-independent operation
•All VariTrane
pneumatic controllers use the patented flow
sensor input to provide the most accurate performance
available.
Binary Input Controller
Binary Input Controllers are system level controllers design to
communicate with the VAV boxes via external binary inputs
using the Trane Comm4 standard with VAV units that have VAV
UCM DDC controllers installed. This non-programmable
controller satisfies critical requirements for systems that do
not need the full functionality of a true Building Automation
System (BAS).
