Description of function - Troubleshooting
The thermostat with rotary switch is controlled by a thermosensor, mounted to the
outlet of the heating coil.
In the electro distributor box (11) mounted to the combustion unit, there is a fuse,
which protects the motor (9) for the fuel pump and ventilator. If the motor is overloaded,
the fuse blows. This can happen when the fuel pump is blocked or does not work
freely, when the ventilator is blocked or does not operate freely or when there is an
electrical problem.
There is a thermosensor (18) in the waste gas tube, which controls an excess
temperature relay with trigger function (4), i.e. when the exhaust gas temperature in
the chimney increases above 230 °C, this relay triggers. To activate it again, you must
wait until the combustion unit has cooled, i.e. approximately 15 minutes. Then, you
can press the button under the cover (14) again. The excess temperature relay can
trigger when the machine is operated over a longer period in the highest steam level, or
when there is lots of soot on the heating coil due to poor combustion, or when the
inside of the heating coil is calcified, so that there is no ventilation (cooling).
As further safety function, the burner is also switched off, when the water
temperature exceeds 147 °C.
