The manufacturer of VAV box units (OEM) generally configures and assembles VAV
compact controllers. VAV control core parameters are therefore protected against
unauthorized changes after production. For configuration and maintenance the service tools
AST20 (handheld tool) or ACS931 / ACS941 (PC tool, to be used with AST11) are available.
