VZ7260 Integration
Please note that no special programming or network bindings are required for the Zoning system to operate. As
such the VZ7260 Zone controllers and their associated VZ7656 RTU controller can operate in stand-alone mode
with all required data transfer binding already handled by the controllers themselves. If BACnet supervision is
added, it is only for GUI, trends, logs or remote views of the devices. The zoning system operation is already taken
care of by the controllers themselves.
The example showed below is valid on MV 7 (Network Handle) index being: 1
– Default Zone Handle. As such
outdoor temperature, Zone mode and Zone Occupancy are NOT dependent on the BAS font end and are objects
dependent on the attached VZ76561000B RTU controller
All object names staring with a “GUI” prompt are normally used for graphic GUI views.
All object names staring with a “Sta” prompt are Status normally used for graphic GUI views.
All objec
t name staring with a “Cfg” prompt are associated to configuration properties of the controller and
typically do not need to be associated to any GUI views
If your BAS allows you to remove objects from your database, Viconics recommends removing all configuration
objects once your setup is complete. This will prevent unnecessary polling of non-used objects and will help speed
up your network.
The following figure shows the typical objects from the controller which can be monitored and commanded from a
BAS front-end.
The following objects could be typically used in a GUI:
Room Temperature (AV 21);
Occupied, Stand-by and Unoccupied Heat Setpoints (AV 11, AV 13 and AV 15);
Occupied, Stand-by and Unoccupied Cool Setpoints (AV 12, AV 14 and AV 16);
Outdoor Temperature (AV 22); Value from VZ7656
UI3 Status / Supply Temperature (AV 18) (If available);
Occupancy Command (MV 9); Value from VZ7656
RTC Zone Sequencing (MV 10);
Damper Position (AI 1);
AO2 Status (AV 17);
PI Heat Demand & Weighted PI Heat Demand (AV 19 & AV 24)
PI Cool Demand & Weighted PI Cool Demand (AV 20 & AV 25)
