Temperature difference controller EU-21 CWU with LED display
EU-21 CWU temperature difference controller with LED display – precise control for efficient heating systems
The EU-21 CWU differential temperature controller is the perfect solution for modern heating systems where efficient and controlled control is essential. Featuring an integrated LED display and versatile control options, this device offers optimal performance for systems with solid fuel boilers, water-fired fireplaces, or buffer storage tanks.
Perfect for heating systems with buffer storage
Heating systems with a buffer storage tank often pose a challenge when it comes to precise and demand-based control of the heat supply. The EU-21 CWU temperature differential controller was specifically developed for such requirements. Thanks to its ability to effectively charge buffer storage tanks, it ensures optimal heat utilization and prevents energy losses.
The control system enables intelligent control of the charging pump by continuously monitoring the temperature sensors. As soon as the heat source reaches a higher temperature than the storage tank, the pump starts automatically. When the temperature drops, the pump shuts off to avoid unnecessary operating hours. This keeps the system efficient and energy-saving.
Individual adaptation for maximum efficiency
The temperature differential controller offers flexible setting options that meet the requirements of your heating system. The operator can individually adjust the differential between the heat source and the storage tank, allowing the controller to be optimally tailored to the specific system. An adjustable hysteresis also prevents unwanted cycling of the system, which both extends the service life of the components and reduces energy consumption.
The device is equipped with two high-quality KTY81-210 temperature sensors. These provide precise measurements that are displayed in real time on the LED display. The user-friendly interface allows for easy configuration of all settings, making operation particularly convenient.
Comprehensive protection functions for your system
The EU-21 CWU temperature differential controller protects not only your heating system but also the connected devices. The anti-stop function activates the pump for eight minutes every ten days to prevent the mechanical system from seizing. Additionally, the device features an effective frost protection mechanism that automatically activates the pump at temperatures below 6°C to prevent the system from freezing.
These safety features make the EU-21 a reliable solution, especially in demanding environments or when outdoor temperatures are consistently low. These extras ensure that your system remains operational at all times and that unexpected failures do not occur.
Versatile applications
The temperature differential controller is a true all-rounder: It can not only control a charging pump, but also be used for return flow boosters (such as Laddomat or ESBE systems), fans, or solenoid valves. Furthermore, the device can be used as a thermostat. This offers you maximum flexibility and a wide range of application possibilities.
This versatility makes the EU-21 CWU temperature differential controller an excellent choice for a variety of heating systems. Whether in residential homes, commercial properties, or specialized systems, the controller provides optimal control over your heating system.
Sustainable and economical
Another key advantage of the EU-21 is its ability to save energy and thus contribute to sustainability.Targeted control reduces unnecessary operating hours, which not only lowers energy costs but also protects the environment. At the same time, the service life of connected devices is extended because they are subject to less wear and tear.
The intelligent combination of efficiency, protective functions and user-friendliness makes the EU-21 CWU temperature difference controller an investment that pays off in the long term.
