Product Description

The MicroTech II Multiple Air Handler Controller is a controller designed to control a maximum of 8 MicroTech II Applied Rooftop or Self-Contained units in up to four separate multiple-unit control groups, with each group consisting of units with similar type and size. It is also designed to be integrated into BACnet building automation systems.

The controller provides three control strategies: 1) Common Outdoor Air Temperature, 2) Common Control Temperature and 3) Common Duct Static Pressure. Read/write access to temperatures, pressures and control parameters is available using Internet Explorer and the BACnet control network.

BACnet Standardized Device Profile

Based on BIBBs supported, the MicroTech II Multiple Air Handler is a BACnet Advanced Application Controller (B-AAC). Refer to the section below entitled BACnet Interoperability Building Blocks (BIBBs) Supported for a complete listing of BIBBS.
