If the consumption is less than the air output of the compressor, the net pressure increases. When the 
net pressure is higher than the set-point (desired net pressure), the regulator will decrease the motor 
speed. If the net pressure keeps on rising when the motor runs at minimum speed, the regulator stops 
the motor. If the motor is stopped automatically and the net pressure approaches the set-point, the 
regulator will restart the motor
