This broadcast sends the time from the VCM-X’s Internal Time Clock
to all controllers on its local loop. This broadcast needs to be confi gured
on a VAV or Zoning System using the VCM-X with Orion VAV/Zone
controllers. A network communications device is required in order for
this feature to operate, but can also be used to synchronize all control-
lers on the local loop. Select YES to Broadcast Internal Time Clock.
Default is NO.

This is always required when you have VAV/Zone controllers connected
to this VCM-X Controller. This will broadcast the Occupied and Unoccu-
pied Condition of the VCM-X Controller to all VAV/Zone controllers on
the local loop. Select YES to Broadcast Internal Schedule. Default is NO.

This broadcast is to ensure the VAV/Zone Controllers will drive their
dampers to the Max Airfl ow Damper Position during Morning Warm-

1 HVAC Unit w/ Boxes
On Multi. Loops: NO
Use < Or > To Change
Select YES to have all broadcasts that have been confi gured on Confi gu-
ration Screens 43 through 48 sent to all local loops on the entire system,
not just the local loop the VCM-X Controller is on. This is normally
only required if you have a large HVAC unit that requires more than
the 58 VAV/Zone Controllers normally allowed on the local loop. This
allows other VAV/Zone Controllers connected on additional local loops
to receive the required broadcasts. This only is allowed when you have
a single VCM-X Controller with VAV/Zone Controllers on multiple
loops. Other VCM-X or add-on devices may be connected but no other
VCM-X with VAV/Zone Controllers can be connected on the system.
Default is NO.
