Start-up & Commissioning
General
In order to have a trouble free start-up it is important to follow a few
simple procedures. Before applying power for the first time it is very
important to correctly address the controller and run through a few simple
checks.
Controller Addressing
All VAV/Zone controllers are equipped with address switches. If the
VAV/Zone controller is to operate as a Stand Alone controller (not con-
nected to any other HVAC unit or VAV/Zone controllers) the controller
address switch should be set for address 1. When the VAV/Zone con-
troller is to be connected to other controllers on a communication loop,
each VAV/Zone controllers address switch must be set with a unique
address between 1 and 58.
When programming the VAV/Zone controller on a Stand Alone or In-
terconnected System and you are asked to enter the Unit ID, you would
enter the address for the controller you wish to program. When pro-
gramming the VAV/Zone controller on a Networked System and you
are asked to enter the Unit ID, you would first enter the MiniLink loop
address for the loop the controller is connected to and then enter the
VAV/Zone controllers address. See Figure 10 for a diagram depicting
address switch settings.

tion for Interconnected and Networked systems, please see the Orion
System Installation & Troubleshooting Guide.
