The beginning of the commissioning phase assumes that all VAV Compact Controllers are mounted according to the mounting instruction  as well as all other devices according to their mounting instructions.
All devices must be connected to the power supply and bus cabling. Power supply and bus cabling must be tested, especially the communication between setpoint sender and setpoint receiver.
Commissioning of VAV Compact Controllers consists of two parts:
Commissioning of the VAV control function (cf. sections 5.1 and 5.2),
Commissioning of the network integration.
Two basic workflows are supported:
Full or partial configuration by a tool (bus configuration and optionally VAV configuration), usually AST20 or ACS941,
Full or partial configuration over bus, optionally addressing by push-button.
