temperature for a certain time. It should be considered during operation.
Automatic temperature limiter (75°C), located in the heater, after operation (opening of the circuit) due to overheating, returns, after cooling
down, to its original state. It has to be ensured, that any dangerous or unpermitted event does not occur in case of activation of temperature
sensor and after its cooling down.
