1.7.5 Resetting Totals via the Network
Totals are held in non-volatile memory within the display. Each total (flow or auxiliary
input) has a corresponding output variable that transmits the information from the display
to the network. There are two ways to remotely reset totals in the display. This can be
done using individual input variables to command the display to reset specific totals or it
can be done using the nviRequest variable. Using nviRequest allows you to reset each total
individually or all totals simultaneously with one command. See sections 1.7.3 and 1.7.4.1
for specific instructions on how to reset totals.
