Heat Pump Control System

Overview

Heat pumps are integral to a home's heating and cooling system, transferring heat between colder and warmer areas to maintain a comfortable year-round temperature. Equipped with a reversing valve, they can operate in cooling mode by moving heat from inside to outside or in heating mode by transferring heat from outside to inside. With a high coefficient of performance (COP), heat pumps are energy-efficient, offering significant cost savings and reduced environmental impact.

This heat pump control system features a dedicated motor control MCU and modular connectivity options, including a Wi-Fi module. Its adaptable design enables real-time performance monitoring and efficient operation, supporting various sensors and components.

System Benefits:

  • Dedicated motor control MCU ensures smooth and responsive heat pump operation.
  • Power line communication (PLC) and Wi-Fi modules provide stable wired or wireless connectivity.
