1 Specifications/Instructions Infilex AC Air Handling Unit Controller for NC-bus Communication General Infilex AC Model WY5117C1XXX is a DDC controller for AHU. It is installed in a small space such as an AHU control panel. Infilex AC is equipped with inputs and outputs suitable for AHU control, and its software is freely editable in response to the applications. Operator interface and room user terminal are connectable to Infilex AC, supporting you in various situations to operate Infilex AC. Infilex AC also is networked with our BMS via our proprietary protocol NC-bus. Infilex AC sends operating status to the BMS and performs operating management in accordance with the commands sent from the BMS in order for you to integrally control and manage a whole building. The time scheduling function of Infilex AC, on the other hand, enables autonomous-distributed control. AHU: Air handling unit BMS: Building management system DDC: Direct digital control Features Compact design: Small sized body fits inside a control panel of a compact AHU. Wide range of input/output (I/O) combinations: Model with the I/O combination best-suitable for the air conditioning controls you desire, such as outdoor air cooling control, humidification, etc. is selectable. Increase in I/O points: An I/O module is added to Model WY5117C140X for increasing the I/O points. Operator interface (Operator Panel): Operator Panel (panel mount type/integral type) connected to Infilex AC allows you to change the settings of Infilex AC without accessing Infilex AC from the BMS. Room user terminals: User terminal (Neopanel or Neoplate) is connectable to Infilex AC, enabling the room occupants to turn on/off air conditioning unit and change temperature setting. Cooperation with BMS: Infilex AC is networked with our BMS to centrally monitor and control AHU. Autonomous distributed control: Even if a trouble occurs in the BMS, Infilex AC individually performs backup operation to distribute potential risks caused by malfunction of the BMS. Installation: Screwless push-in terminals for I/O reduce wiring workload. Additionally, either DIN rail mount or screw mount is selectable. CE Marking certified product: Infilex AC Model WY5117C conforms to all the applicable standards of CE Marking.

Sheath strip length: 8 mm (Pin terminal cannot be used.) *4 RTD (Pt1000) temperature input is two-wire. Take the measuring error into account because the wire resistance causes measuring error. For instance, 1.25 mm 2 size wire causes approx. 0.1 C measuring error every 10 m. Correct the measuring error by setting Infilex AC. *5 When the valve/damper is connected for the system common wiring, the valve/damper operating current flows through the common line. Hence, the specification is as shown above. For a 20 m long IV 1.25 mm 2 cable, 4-wire connection is necessary to prevent the operating current from flowing through the common line. 7
