Weather-compensated heating circuit controller EU-i-1 CWU for heating and hot water circuits

The weather-compensated heating circuit controller EU-i-1 CWU is the optimal solution for the efficient control of a heating circuit and a hot water circuit. Equipped with modern technology, it enables precise control of the flow and return temperatures as well as convenient remote control via the internet. Thanks to its user-friendly operation and versatile functions, it is ideal for both residential and commercial use.

Intelligent temperature control

This heating circuit controller ensures constant, weather-dependent control of the flow temperature using the included outside temperature sensor. It also controls the mixer motor to ensure a return flow increase when using a four-way mixer. This makes heating more efficient, and you benefit from optimal energy utilization.

The continuous control of a three- or four-way mixing valve, as well as the control of a heating circuit pump and a hot water circulation pump, are also among the special advantages of this controller. Thanks to weather control, the device reacts dynamically to temperature changes and adjusts the heating output accordingly.

Convenient weekly programming

With the integrated weekly programming, the heating circuit controller can be set to reduce temperatures at specific times. This enables particularly energy-efficient operation while simultaneously increasing comfort. The precise time settings allow you to perfectly adapt heating to your daily routine.

Innovative Internet control

For even greater flexibility, the heating circuit controller can be optionally equipped with the DE.529 or DE.645 WIFI RS internet modules. Using the free eModul app, you can conveniently monitor and control the controller remotely. This allows you to adjust the settings and check the current operating status anytime, anywhere.

State-of-the-art equipment

The EU-i-1 CWU scores with a 3"-LCD display with backlight that clearly presents all relevant information. For improved measurement accuracy, several temperature sensors are included, including a boiler temperature sensor, a valve temperature sensor, a return temperature sensor, an outside temperature sensor, and a hot water temperature sensor. A USB port also allows for easy software updates to keep the device always up to date.

The robust housing made of high-quality plastic ensures reliable operation, even in extreme temperatures. This makes the controller durable and resilient, regardless of whether the outside temperature is high or low.

Versatile functionality

The heating circuit controller also offers a potential-free output for controlling external devices such as boilers or heat pumps. The expandable control options—for example, via an optional room thermostat—allow the controller to be even more customized to the requirements of your heating system. A wireless expansion is also available as an option.

Summary

The weather-compensated EU-i-1 CWU heating circuit controller is a versatile and powerful device that prioritizes both efficiency and comfort. Its intelligent temperature control, weekly programming capability, and optional internet connectivity make it an ideal choice for modern heating systems. Thanks to its high-quality features and ease of use, this controller is ideal for both beginners and advanced users.

Rely on innovative heating technology and optimize your heating costs with the EU-i-1 CWU – the perfect solution for sustainable and comfortable heating.
