OEG KSW - Differential controller with 4 TF/PT sensors

Differential controller for solar thermal systems

The OEG KSW differential controller with 4 TF/PT sensors is designed to control solar thermal systems in combination with storage tanks, buffer tanks and additional heat sources. The controller measures temperature differences within the system and controls pumps or switching valves based on current heat demand and available solar energy.

Suitable for storage tanks, buffer tanks and heat sources

This differential controller is suitable for various hydraulic configurations, including solar hot water systems, buffer tank systems and installations where solar thermal energy is combined with a boiler, heat pump or another heat source.

Graphical user interface with start-up assistant

The controller features a graphical user interface for clear and intuitive operation. The integrated start-up assistant supports installers during initial configuration, making commissioning faster and easier.

Integrated data logger

The built-in data logger records controller settings, system functions and temperature data. Excessive temperatures are also stored, making system analysis, maintenance and troubleshooting more efficient.

Simulation program for testing and troubleshooting

The simulation program allows system functions to be tested without fully activating the installation. This helps installers verify pump and valve operation and identify faults more quickly.

Anti-blocking protection during long standstill periods

If the system remains inactive for a longer period, the anti-blocking protection periodically activates pumps and switching valves. This helps maintain component function and reduces the risk of blocking.

Wall-mounted housing for professional installations

The OEG KSW differential controller is supplied in a housing suitable for wall mounting. This makes it ideal for plant rooms, solar thermal systems and professional heating projects where reliable control and clear installation are required.

Support from Hewa
