ACS30 user interface terminal
Cold Water or LPHW Services - Multi-Circuit, Distributed Digital Control System, Single or Multi-Application For multiple trace heating applications. The pipe freeze protection circuits shall be controlled and monitored using a centralised control system with distributed power and control modules, complete with colour LCD touch screen, password protected user interface terminal (UIT) for central programming; power connection modules (PCM) to provide distributed power, circuit protection, control & monitoring; remote monitoring modules (RMM) for additional temperature measurement; integrated energy saving proportional ambient sensing programmable controller (PASC); BMS interface using ProtoNode high performance multi-protocol gateway, to allow translation from native ModBus to BacNet protocols; pre-programmed parameters, to deliver concurrent control for heating cables used for pipe freeze protection, hot water temperature maintenance, flow maintenance, surface snow melting, roof/gutter de-icing and floor heating applications.
One UIT shall be included in the system, along with at least 1 PCM (to maximum 52), each PCM shall control up to 5 circuits. The UIT shall accept up to 16 RMM, each having up to 8 temperature inputs. This enables the control of up to 260 heating circuits and is controlled by either RS485 , RS232 or 10/100 Base-T Ethernet communication ports to allow communication with external distributed control systems or BMS Systems. The ACS30 is designed for indoor use in non-hazardous location installations.
