The A-ENA Micro Temperature Sensor is secured to the Thermoblock with a T25 Torx screw. The other end connects to the power board. It measures the temperature of the thermoblock and trasmits the reading to the board. When the required temperature is reached for the selected function, the board allows the coffee machine to proceed to the next step. If a faulty reading is given, an
Error Code will be displayed, or a series of flashing lights will result.
