201910 | User Manual AIAS | 3/24 General System Description AIAS is a pre-programmed, easy configurable and operable control system for optimising the energy consumption in demand oriented building ventilation systems with VAV controllers. The minimal configuration of AIAS system is based on one central control unit called AIAS-Combox. It is a compact DDC-controller with pre-programmed functional blocks for optimizing ventilation system energy consumption.
/24 | User Manual AIAS | 201910 The configuration can be extended by adding next AIAS Combox units each for additional up to 30 rooms aerated by the same AHU. So the configuration can be scaled up to virtually unlimited number. The real limitation is the number of rooms aerated by the same AHU. The master AIAS Combox tops the chain of control signals from all slave units. It generates the power control signals for the Supply and extract fan. Room 15 Room 15 Room 15 Fig.
201910 | User Manual AIAS | 5/24 Detailed Topology The operation of AIAS optimizing system is based on the reading of the position of the VAV controller dampers. The damper position information can be transmitted in two different ways: 1. Analog signal (DC 0-10 V or 0-10 kOhm) These signals are collected in AIAS RIO (remote input/output) module and transferred to AIAS Combox via Exoline communication bus. There can be two RIO modules each with 16 analog inputs used for one Combox.

/24 | User Manual AIAS | 201910 Installation It is recommended to use shielded cables for communication between main controller, room units and damper actuators. These cables must be separated from power supply cables for equipments like motors to prevent interferences. As much distance as possible should exist between communication and power supply cables, especially if they are installed parallel to each another. Maximum length for communication cable is 1000 meters.

201910 | User Manual AIAS | 17/24 System Configuration Addressing The communicating system components like room controllers, VAV controllers, remote I/O modules must have assigned unique addresses identifying them at the bus communication. The unique addresses of the room controllers and the RIO modules communicating on EXOLine are set for each device by the manufacturer. They are composed of two numbers PLA(3 digits), ELA(3 digits).
/24 | User Manual AIAS | 201910 AIAS Configuration Tools The AIAS system is based on pre-programmed software modules that can be assigned to physical objects (sensors, controllers, actors), activated and adjusted in configuration menu by a display tool. The mobile display tool can be connected to AIAS Combox by a cable with RJ12 connector. Lower the main configuration points are shown (pages 17 - 22).
