1.4 ACS FEATURES
The following paragraphs briefly describe some of the unique features incorporated in the ACS.
1.4.1 Simplified Installation and Set-Up
The ACS system operates on single-phase input power ranging from 85 to 265 VAC, 50-60 Hz.
Connections to the boiler plant are accomplished utilizing a 2-wire RS485 network connected in
a daisy-chain configuration. When an EMS or BAS is used with the ACS, connections are made
via the RS232 port terminals. In the event that the EMS or BAS is not equipped with a RS232
port, the ACS can be ordered with a RS485 to RS232 Converter which can be easily installed
within the wiring compartment of the ACS. With the exception of AC power, interlock and
setback inputs and relay outputs, ACS connections are accomplished using shielded-twisted
pair cable.
1.4.2 User-Friendly Control System Interface
The unit incorporates a menu-driven architecture which is comprised of 9 primary menus. The
user interface to these menus is accomplished via the ACS control panel and a Vacuum
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.
