digital pump controller EU-21 with pump protection

Digital pump controller EU-21 – Precise control for your heating systems

The EU-21 digital pump controller is the ideal solution for precisely and efficiently controlling your heating systems. Whether controlling a charging pump on a boiler or a diverter valve, the EU-21 ensures optimal functionality and prevents heat loss. This compact device impresses with its user-friendly operation, precise temperature control, and numerous useful features.

Precise temperature control for maximum efficiency

The EU-21 is characterized by its precise temperature control, accurate to within one degree. This ensures optimal operation of your heating system by preventing energy losses due to buffer cooling. Once the set temperature is reached, the controller switches the connected pump or diverter valve on or off. This ensures efficient use of the heating capacity and prevents unnecessary device operation.

This feature sets the EU-21 apart from conventional pump thermostats and ensures greater efficiency and a longer service life for your heating system.

Easy operation thanks to LED display

A clear LED display allows for intuitive operation and provides you with a precise overview of the current temperatures at all times. Temperatures are displayed in real time, allowing you to optimally monitor the control of your heating system. Thanks to the simple menu navigation, setting up the device is straightforward and requires no special prior knowledge.

The modern display is also easy to read, which further increases comfort during use.

Versatile functions for more safety and comfort

The EU-21 digital pump controller offers a variety of useful functions that make the operation of your heating system safer and more convenient:

• Anti-stop function: This function prevents the pump from seizing during longer downtimes and thus ensures long-term functionality.
• Antifreeze function: The integrated frost protection mode automatically activates the pump when the temperature falls below a critical range, thus protecting your system from frost damage.
• Thermostat mode: The EU-21 can also function as a thermostat and can therefore be individually adapted to your needs.

High-quality equipment for a long service life

The EU-21 comes with a robust heating temperature sensor that reliably measures temperatures and transmits them to the controller. The high-quality workmanship ensures a long service life and stable performance. The device is universally applicable and suitable for both residential heating systems and industrial applications.

The compact and robust housing not only ensures an attractive appearance but also protects the electronics from external influences, which is particularly important in demanding application situations.

Why the EU-21 is the right choice

With the EU-21 digital pump controller, you're investing in quality, efficiency, and safety. This device is the perfect solution if you want to optimize your heating systems and reduce operating costs. Thanks to its versatile features and intuitive operation, the EU-21 is an easy way to improve your system's performance and ensure long-term stability.

Its precision, versatility and durability make the EU-21 an indispensable component of any heating system.
