The handheld tool is powered and the communication link between unit and VAV
compact controller is established via one of the enclosed 3-wire connecting cables.
When power is turned on, the AST10 is ready for operation after about 5 seconds,
that is, the parameters can be set and read. The LCD displays "Srch" both during
the time communication is opened – on startup – and when communication is
interrupted.
When a setting was changed, it can be saved in the VAV compact controller by
pressing the "Set" button.
When pressing the "Factory settings" button, the OEM factory settings will be
retrieved. If, in place of the factory settings, the Siemens default settings appear,
they were not overwritten by the manufacturer of the air volume controller. In the
event of communication problems with VAV compact controller, the LCD displays
"Err".
The LCD displays the available functions as follows:
