Addressing & Powering Up
Figure 17: Address Switch Setting
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 Non-Modular VAV/Zone Controller Actuator Packages are equipped
with address switches. If the Non-Modular VAV/Zone Controller Actua-
tor Package is to operate as a Stand Alone controller (not connected to
any other HVAC unit or VAV/Zone Controller(s)), the controller address
switch should be set for address 1. When the Non-Modular VAV/Zone
Controller Actuator Package is to be connected to other Non-Modular
VAV/Zone Controller Actuator Packages on a communication loop, each
Non-Modular VAV/Zone Controller Actuator Package’s address switch
must be set with a unique address between 1 and 58.
When programming the Non-Modular VAV/Zone Controller Actuator
Package on a Stand Alone or Interconnected System and you are asked
to enter the Unit ID, you would enter the address for the controller you
wish to program. When programming the Non-Modular VAV/Zone
Controller Actuator Package on a Networked System and you are asked
to enter the Unit ID, you would first enter the
MiniLink PD loop address
for the loop the Non-Modular VAV/Zone Controller Actuator Package
is connected to and then enter the Non-Modular VAV/Zone Controller
Actuator Package’s address. See
Figure 17
for a diagram depicting
address switch settings.
For detailed information regarding communication wiring and connec-
tion for Interconnected and Networked systems, please see the
Orion
System Installation & Troubleshooting Guide.
Power Wiring
One of the most important checks to make before powering up the system
for the first time is to confirm proper voltage and transformer sizing for
the Power/Comm board that is connected to it. Each Non-Modular VAV/
Zone Controller Actuator Package requires 6 VA of power delivered
to it at 24 VAC. See
page 15
of this manual for complete wiring and
transformer sizing information for the VAV/Zone Controller.
Check all modular connectors to be sure they are completely pushed and
locked into their mating connectors. Confirm that all sensors required for
your system are mounted in the appropriate location and that the modu-
lar cables are plugged into the correct connectors on the Non-Modular
VAV/Zone Controller Actuator Package. Check the actuator cable and
be sure it is plugged in and secured to the modular connector on the
actuator and the Non-Modular VAV/Zone Controller Actuator Package
circuit board modular connector. Check that the Modular Room Sensor
modular connector is connected to one end of the modular sensor cable
and the other end is connected to the modular sensor connector on the
VAV/Zone Controller Actuator Package. Be sure any Expansion Modules
connected to the Non-Modular VAV/Zone Controller Actuator Packages
are also correctly wired per the Expansion Module wiring instructions
on pages 10 through 14 of this manual.
After all the above wiring checks are complete, apply power to the
transformer(s) that is connected to the Non-Modular VAV/Zone Con-
troller Actuator Packages.
