/**
* Thermal Protection parameters

/**
* Thermal Protection protects your printer from damage and fire if a
* thermistor falls out or temperature sensors fail in any way.
*
* The issue: If a thermistor falls out or a temperature sensor fails,
* Marlin can no longer sense the actual temperature. Since a disconnected
* thermistor reads as a low temperature, the firmware will keep the heater on.
*
* The solution: Once the temperature reaches the target, start observing.
* If the temperature stays too far below the target (hysteresis) for too long (period),
* the firmware will halt the machine as a safety precaution.
*
* If you get false positives for "Thermal Runaway" increase THERMAL_PROTECTION_HYSTERESIS and/or THERMAL_PROTECTION_PERIOD
