Through various Internal monitoring mechanisms ensure that there is no damage to the plastic of the thresholds or overheating. The electronics can be used digitally or analogue (with any voltage). In the digital one you can optionally switch or activate the automatic system manually so that the temperature is maintained. The upper and lower temperatures can be adjusted via CV. If the temperature falls below the lower temperature, the heating switches on and heats until the upper temperature is reached. This means that no additional electricity is required for normal operation. During heating, a current consumption of up to 1A can occur for the heating.
