TECH EU-81 zPID boiler control PID heating controller with flue gas sensor

The TECH EU-81 zPID is a microprocessor-controlled heating controller for solid fuel central heating boilers. Thanks to PID control and an exhaust gas sensor, it ensures a stable boiler temperature, efficient combustion, and reduced emissions. Suitable for wood, coal, and pulverized coal boilers.

Highlights/Advantages

⭐ PID control with exhaust gas sensor – constant boiler temperature and clean combustion
⭐ Control of heating pump, hot water pump and fan
⭐ Fuel selection for wood, coal and coal dust
⭐ Multiple operating modes including summer mode and hot water priority
⭐ Increased efficiency and longer boiler lifespan

Detailed description

Area of ​​application & Target audience

The EU-81 zPID was developed for solid fuel central heating boilers. It is suitable for both residential heating systems and smaller commercial applications where precise temperature control is required.

Everyday benefits

By continuously measuring the exhaust gas temperature, the controller automatically adjusts the fan speed. Temperature spikes are avoided, fuel is used more efficiently, and heating comfort is significantly increased.

Technology & equipment

The integrated PID control system regulates the combustion process with exceptional precision. In addition to the boiler sensor, an additional exhaust gas sensor is integrated, which monitors the combustion quality and reduces or switches off the fan as needed.

Efficiency & Environment

Even combustion reduces fuel consumption and emissions. The heat contained in the exhaust gas is optimally utilized instead of escaping unused through the chimney.

compatibility & System integration

The controller manages a heating pump, a hot water pump, and the supply air (blower). Various operating modes allow for flexible adjustment to heating and hot water requirements.
