AERCO Control System (ACS)

This state-of-the-art plant management solution will enable customers with more than one boiler to maximize energy savings through the coordinated operation of up to 32 Benchmark, KC1000 or Modulex boilers.

Features and Benefits

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. AERCO also offers a Communications Gateway to support BACnet, Lonworks and N2 system integration.

The ACS is specially designed to leverage the operating efficiency of condensing, gas-fired boilers capable of unmatched 20:1 turndown. It comes equipped with a Header Temperature Sensor and offers customers sequential or parallel application, constant or remote set point operation and provides 100% control of auxiliary boiler equipment while equalizing unit runtime in the boiler plant.

Three domestic hot water heating modes allow application flexibility:

  • Header Temperature Boost – Benchmark, KC1000, and Modulex boiler applications
  • Domestic Hot Water (DHW) Priority – Benchmark and KC1000 boiler applications
  • DHW priority + building priority (swing boiler) – Benchmark and KC1000 boiler applications

BAS-equipped customers can be notified of faults throughout the boiler plant and can remotely examine up to 35 aspects of each boilers operation through a single connection point.

Options and Accessories

AERCO / ProtoNode Gateways
AERCO offers a multi-protocol, communications gateway to support integration with customers’ building control and energy management systems. The plug-n-play package supports integration with BACnet/IP, BACnet MS/TP, LonWorks, and Johnson Controls Metasys N2 systems. AERCO’s Communications Gateway is available for all AERCO boilers, *water heaters and electronically controlled indirect systems.

ACS Outdoor Air Sensor Kit
