When the absolute value of error is less than this range, the PID function stops. When the
feedback reaches at the given value for the first time, the limit deviation starts to act, PID
function stops, when beyond the range, the limit deviation fails and the PID restarts to
work.

Through this function code, you can select oil temperature, motor temperature (supports a
variety of sensors) and air pressure sensor. If an interface card is used, temperature sensor
can be adopted with PT100 .
