Description
The central piece of the AIAS optimizing system for
the demand oriented air handling, ow control and
distribution is the AIAS “combox”. It coordinates the
operation of air handling untit with all the individual
room control elements by a tailored digital control
solution without need of additional coding. It covers
also the communication functions for direct or remote
parametrizing, messaging, management, commissioning,
maintenance and BMS integration. The customized set-
up, recognition and assignment of the system elements
at initial start-up is easy and intuitive using a setup
menu.
The capacity of a single AIAS “combox” is sufcient to
operate with up to 30 individual room VAV-control loops,
where each can contain app. 10 data points (control
and measurement variables). The positions of the VAV-
controllers are examined separately air supply and for
air extract. This enables AIAS “combox” to generate
optimized control values individually for the supply and
the exhaust fan on the AHU.
