Function:
 PID control (direct action)
The Manipulated output value (MV) increases as the Measured value (PV) increases.
This action is used generally for cool control.
 PID control (reverse action)
The Manipulated output value (MV) decreases as the Measured value (PV) increases.
This action is used generally for heat control.
