The TECH EU-81 zPID HG is a microprocessor-controlled boiler control unit with PID control, specifically for wood gasification boilers. It controls the fan, heating and hot water pump and optimizes the combustion process via an additional flue gas sensor.
Highlights / Benefits
⭐ Specifically designed for wood gasification boilers
⭐ PID control with additional flue gas sensor
⭐ Constant boiler temperature and stable operation
⭐ Reduced emissions through optimized combustion
⭐ Control of fan, heating and hot water pump
Detailed description
Area of application & target group
The EU-81 zPID HG is intended exclusively for operation on wood gasification boilers . It is suitable for heating systems in residential areas as well as for technical applications where precise temperature and combustion control is required.
Everyday benefits
Thanks to PID control with flue gas sensor, combustion is continuously monitored and adjusted. Temperature fluctuations are minimized, and the boiler operates more quietly and efficiently. This increases operating comfort and supports uniform heating operation.
Technology & equipment
The control unit regulates:
In addition, a flue gas sensor permanently monitors the flue gas temperature. If the temperature rises, the fan output is automatically reduced or switched off to prevent overheating.
Efficiency & environment
Controlled combustion ensures uniform heat generation and can reduce fuel consumption. At the same time, emissions of dust particles and gases are reduced because the heat energy of the flue gases is better utilized.
Compatibility & system integration
The EU-81 zPID HG is designed for classic hydraulic heating systems with wood gasification boiler. Various operating modes such as heating mode, parallel pumps, summer mode or hot water priority allow flexible adaptation to the system.
