Control System for Domestic Hot Water in District Heating Units

Optimizing Resource Consumption

The development of district heating and district heating units is continuously evolving, with a strong focus on optimizing resource consumption. The size of a district heating unit is also important to end-users, who typically prefer a compact unit that does not take up much space.

By utilizing fast valve motors and precise flow and temperature measurements, it is often possible to reduce or completely eliminate the need for buffer or water tanks. This not only reduces resource consumption in the production of the district heating unit but also allows for a more compact and aesthetically appealing design.

Requirements for the Control System

Such solutions impose several demands on the control system. The control unit should be positioned precisely where measurements and regulation are needed. Placement close to the components ensures that microprocessors can operate at high speeds and with high resolution, allowing for more accurate and efficient control.

With extensive experience in this field, participation in various projects with comprehensive and long-term testing has led to outstanding results. One example is a compact control unit, ideal for managing domestic hot water in homes connected to district heating. Once installed in a compact system, it ensures a comfortable and stable water temperature, preventing scalding risks for users.

Advanced Control and Energy Optimization

This small and compact control unit functions as a fast and precise stepper motor controller, based on highly accurate flow and temperature sensors. The software is equipped with well-tested and advanced control algorithms to ensure the precise regulation necessary for these applications.

Additionally, the control system adapts to different load cycles and optimizes energy consumption through standby modes or pre-programmed energy-saving functions, significantly improving the efficiency and operating costs of domestic hot water supply.

Flexible Communication Interfaces

By default, the control unit uses ModBus as an interface. However, if you require a different communication protocol, such as I2C, CAN-Bus, or other commonly used bus systems, for internal communication between products, the control system can be delivered with your preferred interface.
