What Is Unique About Orion?
Patented Flush Mount Room Sensors
Our flush mount room sensors are so unique, they are
patented (U.S. Patent No. 4,659,236). Even though part
of the sensor is recessed into the wall to provide an
attractive yet tamper proof flush mounting, internal wall
temperatures do not influence the sensor. A special plate
on the face of the sensor accurately senses space tem-
perature. Even though the attractive off white plastic
housing is a preferred color, the sensor housing can be
painted or wallpapered to blend with room decor with-
out affecting sensor performance. The sensors are of-
fered in four different configurations:
• Sensor
• Sensor w/override
• Sensor w/setpoint adjustment
• Sensor w/setpoint adjustment & override
Modular Connections
The VAV/Zone Controllers used with the Orion Sys-
tem are designed with modular connections for easy,
error free wiring. A Power/Comm board is used to sup-
ply power and communications to the branch circuits.
The VAV/Zone Controller boards and the Power/Comm
board are provided with Molex
 connectors. Prefab-
ricated cables with Molex
 connectors are supplied in
various lengths for connection between the VAV/Zone
Controllers and the Power/Comm Board. In addition to
the power and communications wiring between the
Power/Comm Board and the VAV/Zone Controllers
many Orion auxiliary devices are connected to the con-
trollers via modular plugs like the ones used on tele-
phones. This also simplifies installation and eliminates
the possibility of wiring errors. The devices, which uti-
lize this method are the damper actuators for zone con-
trol, modular room sensors used with the zone control-
lers, auxiliary relay boards, and static pressure/air flow
sensors. There is one interesting side note about the
auxiliary relay board and airflow sensors. These devices
are typically used on the zone controllers in the Orion
systems. When the system is powered up, it automati-
cally looks to see if these devices are connected to the
controller. If they are, the controller automatically
reconfigures itself to utilize these devices and activates
the appropriate set up screens back at the operators in-
terface. This feature makes setup a breeze!
FREE! Windows™ Graphics Software
Each Orion system can be monitored on site or remotely
using a PC and our Windows 98, “Prism” computer front
end software. This full-featured package is very user
friendly and can be used to monitor one system or hun-
dreds. Prism is not copy protected so it can be installed
on multiple PC’s’ without additional expense. Just some
of its many features include but are not limited to:
•
Pre-designed status screens for all controllers
•
Alarm dial out capability
•
Programming of all system parameters
•
Trend logging
•
Alarm Handling
•
Custom graphics capability
Open Protocol System
Orion is an open protocol based system allowing other
manufacturers to develop direct interfaces to the com-
munications loop. This gives you the ability to inte-
grate the Orion system into products from other ven-
dors. Our engineering staff will be glad to assist any
vendor in this process.
