Fireplace control EU-391 zPID – Efficient solution for water-bearing fireplaces

The EU-391 zPID is a modern control unit specially designed for water-bearing fireplace stoves and fireplace inserts with an outside air connection. Its innovative technology ensures optimal combustion and maximum energy efficiency. Whether you want to heat your home sustainably or increase the efficiency of your fireplace stove, this control unit offers you a future-oriented solution.

Precise control of combustion air thanks to PID algorithm

The EU-391 zPID operates with a sophisticated PID algorithm that regulates the amount of combustion air depending on the water and flue gas temperatures. This algorithm continuously adjusts the stove's output to the detected temperature values. This ensures more efficient, economical, and environmentally friendly combustion. This advanced technology achieves higher energy yield and reduced fuel consumption.

The included motorized air damper is available in three diameters (100 mm, 120 mm, and 150 mm) and allows precise control of the supply air. This feature contributes significantly to improving heating comfort and energy efficiency.

Versatile applications

The EU-391 zPID is versatile and suitable for all water-bearing fireplace stoves and fireplace inserts with an air supply connection. In addition to regulating combustion, the control unit can also manage several heating system components. These include:

• Buffer charging pump
• Heating circuit pump
• Domestic hot water storage pump
• Oil or gas boiler via voltage-free contact

These versatile connection options make the control unit an ideal companion for an efficient and networked heating system.

Intelligent buffer management and additional functions

The EU-391 zPID supports intelligent buffer management, which optimizes the water temperature in the stove and the buffer tank. Sensors continuously measure the temperatures in the stove and in the upper part of the buffer tank. A connection for a domestic hot water tank sensor is also integrated to ensure a constant supply of hot water.

Another special feature is the ability to connect the control system to an internet module from Tech. This allows you to conveniently monitor and control your heating system via an app.

Environmentally friendly and future-oriented

The EU-391 zPID stands out for its environmentally friendly technology. Thanks to precise control of the combustion process, less fuel is required, reducing CO₂ emissions. At the same time, you benefit from a longer service life for your stove and a functional connection to supplementary heating sources such as oil or gas boilers.

Thanks to its advanced technology, the fireplace control system meets all the requirements of modern heating systems and thus sets the standard for the future of energy-efficient heat supply.

Conclusion: Your benefits at a glance

With the EU-391 zPID, you get a sophisticated and versatile control solution for water-bearing stoves. Intelligent combustion control increases efficiency and reduces fuel consumption, while the system offers maximum flexibility through numerous connection options. Furthermore, support for additional functions such as the internet module and intelligent buffer management ensures maximum convenience and efficiency.

Increase the performance and sustainability of your heating system – the EU-391 zPID is the perfect choice for modern and environmentally conscious heating solutions.
