BACnet Packaged Unit Controller

The ASIC/1-8100 BACnet Packaged Unit Controller combines the functionality of an ASI Air Conditioner or Heat Pump controller with the interoperability of the BACnet open protocol and assurance of BTL certification.

The ASIC/1-8100 digital controller includes sequences for control of packaged Air Conditioner units and Heat Pumps in new construction and retrofit applications. The controller maintains temperature by turning on and off stages of heating or cooling, with selectable personalities for one and two stage heat pumps and up to four stage air conditioning units.

The controller monitors temperature through a wall sensor. WS-0x1 series sensors including the WS-061 Digital Display wall sensor can be used with the ASIC/1-8100. Control of indoor fan and optional auxiliary cooling and auxiliary electric or gas heat are included. An optional economizer can be controlled by discharge air or mixed air temperature and the optional changeover analog output can be used for hydronic heating or cooling.

ASIC/1-8100 controller can communicate on the BACnet MS/TP bus and can also talk through a WS-0x1 wall sensor using ASI protocol.  An ASIC/1-8100 on a BACnet network is configured from ASI Visual Expert.
