2.4 Controls Interoperability
The communications module utilizes the MODBUS open protocol to interface with third party
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.
