Building Automation Systems (BAS).
The controls interface with BACnet, Lonworks, and N2, shall utilize an optional AERCO
Communications Gateway to act as a MODBUS interface/translator between the BAS the
communications. The AERCO Communications Gateway is comprised of a microprocessor based
control utilizing the MODBUS protocol to communicate with the boilers. Non-volatile backup of
all point mappings and programs are internally provided as standard. Connection between
Gateway and individual boilers shall be "daisy chain" with shielded, twisted-pair, and low voltage
wiring for ease of installation.
