If a database is downloaded to the controller after the box has been balance will it lose the balance data?

  • MNB-V1

Cause

In MNB VAV controllers the flow balance data is preserved in a different area of EEPROM than the application data.

Resolution

Balance data in an MNB VAV controller is not affected by the downloading of its database.
