Air Flow Monitoring Station
Installation and Wiring
The E-BUS Distribution Module is used to connect selected Air Flow
Monitoring Stations to the VCM-X Controller. Currently, there are two
Air Flow Monitoring Station options that are supported in our standard
software.
• EBTRON
®
- GTC-116 Series Air Flow Monitoring Station*
• GreenTrol™ Automation - GA-200-N Module used with
any GF Series Air Flow Monitoring Station
*NOTE: When confi guring the GTC-116 Series, be sure to set
the Parity to “NO PARITY, 1 STOP BIT.”
The Paragon MicroTrans EQ series Air Flow Monitoring Station is
supported only on the VCM-X Controller using custom software.
Contact the WattMaster factory for more information. The wiring for
these options are the same and are shown in Figure 6.
The E-BUS Distribution Module provides a communications interface
into the VCM-X Controller to enable it to monitor and display the
airfl ow readings of these air fl ow stations.
NOTE: Only one E-BUS Distribution Module can be used per
control system.

WARNING!!
Observe Polarity! All boards
must be wired with GND-to-GND
and 24 VAC-to-24 VAC. Failure
To observe polarity could result in
damage to the boards.
