5.3 Configuration and maintenance tools
Configuration and retrieval of device parameters can be accomplished with the
following tools:
• Using the PC software ACS941 or ACS931 together with the interface
converter AST22 via the configuration and maintenance interface of the VAV
Compact Controller or
• Using the handheld tool AST20.
5.3.1 PC software ACS941 and ACS931
The PC software versions ACS931 (for OEMs) and ACS941 (for service and
maintenance staff) is used for setting and displaying the parameter values on a PC.
Instructions for use of this software can be found in [7] and [8].
The PC software ACS941 allows to set or to display the parameters as listed in
chapter Fehler! Verweisquelle konnte nicht gefunden werden.. The software
supports trend functions and allows comparing the values set by the OEM with the
values currently stored in the device. Thus, changes by parties other than the OEM
can be detected.
