  • Page 3 1.1) Gasification technology The wood gas (ger. holzgas) comes in the process of gasifing of the wood. This is the mixture of flammable gases: the oxide of carbon, hydrogen and methane, and also incombustible -- nitrogen, the dioxide of carbon, water steam. The composition of the gas depends on many factors as: from current temperature in the hearth of the gas generator, the moisture of the loaded fuel and other.

    Factory defaults The controller allows returning to standard settings set by the producer by choosing [Prod] and pressing OK button. After activating this function, the controller sets each parameter showed in the table. Output testing To make checking the controller work easier, it is possible to test output circuits which control the fan and the pump, and the additional boiler launching system.
  • Page 20 When [E 1] error appears on the display, it means fault in the boiler sensor circuit or temperature below 0°C. [E 2] is displayed if boiler overheats. [E 3] error means fault and overheating at the same time. Appearing of [E 1] error on the display after erasing it by pressing STOP button, in spite of temperature decreasing below 90°C, may mean permanent damage of boiler temperature sensor (e.g.
