Poor. A common complaint is that the transformers and pump remain active even when the front switches are off, leading to "vampire" power draw.

The MCU reads the amplified temperature. If the temperature is below the set point (e.g., 350°C), it sends a pulse to turn on the heater. gordak 952 circuit diagram
