Confi guration Screen #46 - Broadcast VAV
Boxes Force to Max
RNE Cnfg ID 101
Broadcast VAV Boxes
Force To Max: YES
[0=NO 1=YES]
This broadcast is to ensure the VAV/Zone Controllers will drive their
dampers to the Max Airfl ow Damper Position during Morning Warm-
up. This is important to allow the proper amount of airfl ow for Heating
in the HVAC unit. Enter
<1> for YES or <0> for NO. Default is YES.
Confi guration Screen #47 - Broadcast VAV
Boxes Force to Fixed
RNE Cnfg ID 101
Broadcast VAV Boxes
Force To Fixed: NO
[0=NO 1=YES]
Enter
<1>
for YES to have all VAV/Zone Controllers connected to this
RNE Controller forced to their “Fixed Airfl ow” Position during the
Morning Warm-up Mode of operation. Enter
<0> for YES if you do
not want this to occur. See the VAV/Zone Controller Setpoint Screens
for setting of the “Fixed Airfl ow” position. Default is NO.
Confi guration Screen #48 - 1 HVAC Unit with
Boxes on Multiple Loops
RNE Cnfg ID 101
1 HVAC Unit w/ Boxes
On Multi. Loops: NO
[0=NO 1=YES]
Enter
<1>
for YES to have all broadcasts that have been confi gured on
Confi guration Screens 42 through 47 sent to all local loops on the entire
system, not just the local loop the RNE 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 RNE Controller with VAV/Zone Controllers on multiple loops.
Other RNE or add-on devices may be connected but no other RNE with
VAV/Zone Controllers can be connected on the system. Enter
<0> for
NO. Default is NO.
Confi guration Screen #49 - Uses R410A
Refrigerant
RNE Cnfg ID 101
