ENVIRONMENTAL The Greenspec® Listed Benchmark boilers are perfect for “green” designs. Their small footprint, flexible venting/piping options, high efficiency, and lower operating costs can help facilities earn LEED points. Benchmark has been designed with environmental advantages: • O2 monitoring system* – Benchmark units are available with AERCO’s proprietary O2 monitoring system, which displays the oxygen level directly on the C-More controller in real time. It can be monitored via Modbus, so customers can measure emission levels and fuel combustion efficiency to maximize fuel economy. *Note-...

ACCESSORIES AERCO Control System (ACS) Strongly recommended to maximize modular heating plant efficiency, AERCO Control System (ACS) offers remote access and control of multiple boiler installations and is compatible with Building Automation Systems via Modbus open protocol or conventional analog systems. Boiler Valve Control Designed for variable flow heating systems, the AERCO Boiler Valve Controller automatically sequences each motor operated valve* (MOV) – reducing the system’s minimum flow requirement to a single boiler’s minimum flow. For example, a four BMK2.0LN installation without MOV...
