  • Page 11: Chapter 1: Acs General Information

    The ACS (Figure 1-1) is a rugged and flexible controller, designed to stage and coordinate the operation of up to 32 AERCO Benchmark Series, Modulex Series or KC1000 Boilers while maximizing operational efficiency. Under normal load conditions, the ACS can precisely regulate the header temperature of the boiler plant within ±2°F.

    Fluorescent Display (VFD). The display is capable of displaying two lines with 16 characters per line. Virtually all of the control panel keys are identical to the C-More Control System currently used on AERCO Benchmark Series and KC1000 Boilers. This commonality will help simplify the time required for system setup of the ACS.

  • Page 22: Rs485 (Modbus) Wiring At The Acs

    CHAPTER 2: ACS Installation RS485 (MODBUS) WIRING AT THE ACS The ACS communicates with the AERCO Boilers over a RS485 network using Modbus protocol. All Modbus networks are implemented utilizing a Master/Slave scenario where only one device, the Master, can initiate a communication sequence. AERCO Boilers equipped with C-More or E8/BCM (Modulex) control systems can only function as Slaves on a Modbus network.
