IC revision1

Description

The EU189-HEATPUMPPOCZ reference design provides an e-AI-ready system controller with integrated HMI capabilities. It manages system-level functions by processing data from environmental and motor sensors and coordinating commands to external motor control boards responsible for driving fans and compressors. With a responsive touch GUI and versatile communication interfaces, it enables intuitive user interaction and easy integration into appliances and industrial systems. The system is prepared to run e-AI for predictive maintenance and optimized system performance by monitoring live feedback from the connected sensors.

Features

Capacitive touchscreen and web-based UI offer intuitive, flexible control and system configuration.Built-in relays allow direct external load control, reducing system complexity and enhancing reliability.Versatile connectivity with RS-485, Ethernet, Wi-Fi, Bluetooth®, and LTE ensures easy integration to both local and cloud-based systems.

Typical applications

  • Smart homes, Smart kitchen appliances, Residential and commercial heat pumps (>4kW to 7kW electrical power)
