VZ7656 Integration
Please note that no special programming or network bindings are required for the Zoning system to operate. As
such the VZ7260 Zone controllers & 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.
 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 object 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 can be monitored and commanded from a BAS
front-end.
The following objects could be typically used in a GUI:
 Return Air Temperature (AI 2); Outdoor Temperature (AV 19); Discharge Air Temperature (AI 1)
 Return Air Occupied and Unoccupied Heat Setpoints (AV 9 and AV 10);
 Return Air Occupied and Unoccupied Cool Setpoints (AV 7 and AV 8);
 Static Pressure & Static Pressure Setpoint (A1 3 and AV 4)
 Occupancy (MV 14); System Mode (MV 15); Zone Sequence (MV 4);
 G Fan (BI 1); Y1 Cool (BI 2); Y2 Cool (BI 3); W1 Heat (BI 4); W2 Heat (BI 5);
 Aux Status (BI 7); BI 1 Status (BI 6);
 Filter Alarm (BI 11) (if available); Service Alarm (BI 10) (if available);
 Discharge Air Temperature Alarm (BI 13)
 Current Zone PI Heat Demand (AV 11);
 Current Zone PI Cool Demand (AV 12);
