Invensys ECH 210B Electronic Controller for Mono- and Bi-Compressor Chillers — MW320025

Compact chiller/heat pump controller with MODBUS communication, from the ECH 200 family

Overview

This is an Invensys (Eliwell) ECH 210B, product code MW320025, a compact electronic controller from the ECH 200 family designed to control mono- and bi-compressor chillers. It's built for air-air, air-water, water-water, and condensing units with 1 or 2 compressor steps, offering temperature control based on inlet or outlet probe, condensation control, automatic change-over, and internal fan control. This model includes a MODBUS communication protocol for building management system (BMS) integration and remote-control sensor management via a remote keyboard. Note: this model is discontinued by the manufacturer with no direct replacement currently listed.

Key Features

  • MODBUS communication: Enables integration with building management systems (BMS) for remote monitoring and control.
  • Multiple relay and triac outputs: 4 relay contacts plus triac outputs for compressor, pump, fan, and valve control.
  • Automatic change-over: Supports switching between cooling and heating modes automatically.
  • Programmable via keyboard, copy card, or PC: Parameters can be set through multiple interfaces, including a copy card for uploading/downloading parameter maps.
  • Anti-freeze and hot-start protection: Built-in functions to protect equipment and maintain safe operation.
  • Alarm output: 12-24V AC output for alarm signaling, max. current 500 mA.
