RESOL

Smart control for solar systems with Resol

Anyone using a solar water heater, heat pump boiler or other thermal system knows how important reliable control is. The performance of such a system depends not only on the quality of the panels or boiler, but especially on how the system is controlled. That is exactly where Resol comes in. This German brand has been known for years for its innovative and sustainable control technology for solar energy systems. Their controllers are designed to get the most out of any installation, with smart features that ensure efficiency, safety and ease of use.

Resol Deltasol: the heart of an efficient solar water heating system

Within Resol's product range, the Resol Deltasol series is perhaps the best known. These controllers are used worldwide in solar water heating systems, both in homes and in larger installations. What makes Deltasol controllers so special is their reliability and flexibility. They continuously measure temperatures in the system, control pumps and ensure that heat gets to exactly where it is needed.

A Resol Deltasol works not just as a simple thermostat, but as an intelligent brain that takes into account temperature differences, safety, efficiency and energy savings. This keeps the system stable and efficient even when conditions change. Whether it is a sunny summer day or a cold winter morning, the Deltasol controller ensures that the system continues to function optimally.

Resol VBus: communication that makes systems smarter

One of the biggest advantages of Resol technology is the Resol VBus communication system. This is a digital data bus that allows different components within the installation to communicate with each other. Thanks to VBus, you can read out data, log it and even monitor it remotely. For installers and users, this means you always have insight into the system's performance.

Resol VBus makes it possible to track trends, recognise failures early and optimise settings. It makes solar systems not only smarter, but also more sustainable. By seeing exactly how the system behaves, you can increase efficiency and avoid unnecessary energy consumption. For those who like to keep control of their installation, VBus is a valuable addition.

Deltasol CS Plus: a powerful controller for complex systems

Within the Resol family, the Deltasol CS Plus is one of the most versatile and powerful controllers. This controller is designed for larger or more complex solar systems, where multiple pumps, sensors or heat sources work together. The Deltasol CS Plus can control several circuits simultaneously and offers extensive setting options.

What makes this controller so special is its combination of power and ease of use. Despite its many functions, operation remains clear. The display clearly shows what is happening in the system, and thanks to Resol VBus, you can easily read all the data or link it to external monitoring. This is a big advantage for installers, as the system is quick to set up and requires little maintenance.

Why choose Resol control technology?

Resol has proven to be a reliable partner for solar energy systems over the years. Its products are solidly built, accurate in their measurements and designed to last for years. But perhaps more importantly, they make the most of available solar energy. By smartly switching, measuring and controlling, Resol controllers ensure that every installation performs optimally.

Whether you have a simple solar water heater or an extensive system with multiple heat sources, there is always a Resol solution to suit. From the compact Deltasol models to the advanced Deltasol CS Plus, and from simple monitoring to full data logging via Resol VBus, the brand offers everything needed to keep an installation running reliably and efficiently.
