The user is unaware of the flow linearisation values that are calculated and downloaded to the controller.
As a result, he/she is not sure if the device has been balanced properly. This dialog is provided with the intention of displaying all the related values to the user – default factory calibration values of the device, Flow pickup table configured by the user, calculated flow linearisation values that get downloaded during commissioning and the last set of values are the actual flow values read from the device.
Since this operation involves reading values from the controller, this option is available only in the network’s Connected state. Moreover, the controller should either be in a “Commissioned” or a “Not Commissioned” state.
This dialog displays two sections:
The first section is labeled as “Factory Calibration Values”.
This section displays the default factory calibrated values from the device. The values read from the controller are converted into the project display unit and shown here.
The second section displays three tables:
These are the set of flow pickup table values configured by the user in the “Flow Pickup Table” page of the VAV configuration screen.
These are the values of the configuration variables “nciVoltsCal” and “nciFlowCal” after applying the linearisation formula. These values are not read from the controller.
These are the actual values of the configuration variables “nciVoltsCal” and “nciFlowCal” read from the device.
All the above mentioned values are displayed in the appropriate project display units.
