5.2 Configuration and maintenance tools
Configuration and retrieval of device parameters can be accomplished with the
following tools:
1. Using the PC software ACS941or ACS931 together with the interface
converter AST11via the configuration and maintenance interface of the
VAV Compact Controller or
2. Using the handheld tool AST20.
5.2.1 PC software ACS941 and ACS931
The PC software ACS941 is designed for service and maintenance staff and is
used for setting and displaying the parameter values on a PC. Instructions for use
of this software can be found in datasheet N5854 ([6]).
The PC software ACS941 allows to set or to display the parameters as listed in
section 5.1. 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.

5.2.2 Handheld tool AST20
Using the handheld tool AST20, VAV and Modbus RTU parameters can be set or
retrieved. Instructions for use of the handheld tool AST20 can be found in data
sheet [3].
The AST20 is designed for portable use on-site. Power supply and establishing the
communication between AST20 and a VAV Compact Controller are realized with
one of the connection cables which are shipped with the AST20.
