Method for Controlling a Heating System Component for a Simple and Safe Operation and a Heating System Component Therefore

A method for controlling a heating system component of a heating system for heating a fluid medium,

• said heating system component comprising:
• a carrier unit;
• a heating unit coupled to said carrier unit;
• and
• a controller;
• wherein said carrier unit comprises a wet side and a dry side, wherein said wet side corresponds to a surface of said carrier unit configured to be in contact with said fluid medium, wherein said dry side is located on a surface opposite to said wet side;
• and further comprising at least one temperature sensor, in particular an NTC thermistor, wherein said temperature sensor is effectively in thermal contact with at least a part of an upper surface of said dry side of the carrier unit,
• the method comprising:
• receiving a starting signal at the controller for starting the heating system component;
• carrying out a test routine for at least the at least one temperature sensor;
• and
• in case the test routine is not successful:
• entering a safe state of the heating system component.
