/**
 * Thermal Runaway 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,
 * the firmware will halt as a safety precaution.

 * 81 - Printrboard - Uses Analog input 2 on the Exp1 connector (version B,C,D,E)
 * 301 - Rambo  - uses Analog input 3
 * Note may require analog pins to be defined for different motherboards
