- Control Systems for Heat Pumps
Our expertise in developing electronics for heat pumps began with integrated heat pumps in ventilation systems, where we collaborated with our customers to create some of the best solutions on the market.
This foundation has led to our involvement in various types of heat pumps, including domestic hot water heat pumps and split heat pumps with separate indoor and outdoor units.
Through our development work, we have gained unique expertise in condensers, evaporators, preheating coils, electronic expansion valves, and the interaction between sensors and cooling components. Equally important we have extensive experience in complex defrosting strategies, ensuring the highest possible COP values for the final heat pump system.
The evolving regulations on approved refrigerants have given us a deep understanding of their impact on heat pump performance. We have assisted multiple manufacturers in refrigerant transitions, including compressor replacement, calibration, and system adjustments. In some cases, this has resulted in the development of entirely new products.
When developing new solutions, we optimize for the future from the initial design phase. This means a strong focus on product lifespan, energy consumption, reusability, and supply reliability.
We stay up to date with industry standards and regulations, ensuring full compliance. We are well-acquainted with IEC-60335-2-40 ver. 7, expected to be ratified as EN-60335-2-40 ver. 7 in March 2025, and we readily assist with the necessary documentation.
It is crucial to evaluate optimal cable routing early in the design phase to determine how few PCBs the control system can consist of. A well-structured PCB layout contributes to efficient assembly, easier servicing, and reduced complexity in the heat pump system.
Beyond the control electronics, the frequency inverter plays a vital role in heat pump operation, lifespan, and maintenance. We therefore have our own inverter program, already adapted to a wide range of compressors on the market.
Our extensive monitoring toolbox ensures optimal component interaction during development and field testing, allowing manufacturers to fine-tune system performance before full-scale production.
To simplify setup, operation, and servicing, most heat pumps are equipped with interfaces that allow integration with LS SmartConfig, SmartConnect Center, or other online solutions.
The standard communication protocol is ModBus, with additional options such as Zigbee, Bluetooth, LAN, and WiFi, depending on specific requirements.
With our solid experience and structured development model, we provide reliable, future-ready control solutions tailored to modern heat pump systems.
Since 1969, we have been supplying electronics for control, regulation and control to quality-conscious companies
