  • Page 5 ! Important warning: The stated thermal technical parameters vary in dependence on the sort, quality and moisture of the used fuel. Therefore some corrections might be necessary when setting the stoking cycle (time for fuel feed versus time for fuel afterburning). For example if unburned fuel slivers appear on the grate and in the ash- pan it stands to reason that stoking is faster than burning and the stoking cycle must be reduced –...

    Boiler operation by user Control, regulation and safety elements 6.1.1 Climatix control unit Heating - automatic mode The boiler must be in the ON mode (display of the Climatix control unit ). Heating demand is generated by closing an external control. External control is a potential-free switch contact to which the room thermostat (D1) can be connected at heating to the boiler temperature.

  • Page 32: Safety Thermostat

    Setback mode If there is no demand for heating or hot water, the boiler is in setback mode. This mode is indicated by the green LED flashing on the boiler display. In this mode, the minimal boiler temperature is maintained only by the min. fan power without the pump operation (factory setting 65 °C).
