14.12 Rnet Tags
Rnet tags are numbers that identify types of system values, and determine how the ZS sensor will display those values. For example:
The Rnet tag number 100 indicates Fan Status. The sensor will display a fan icon when the microblock is active.
The Rnet tag number 416 indicates Air Flow Setpoint. Values such as this that do not have an icon will display the Rnet tag number in the
lower left corner of the sensor’s display.
