Question 2

What are proportional controls?
 
  A) Proportional controls integrate the signals from several sensors and control the system operation based on the proportion of sensors requiring conditioning.
  B) Proportional controls increase or decrease the output of a controlled device in proportion to the level of the measured condition.
  C) Proportional controls regulate the starting and stopping of the system to keep the run time ratio as low as possible.
  D) Proportional controls have the ability to measure the controlled variable and the system output and dynamically adjust the setpoint to achieve more precise control.
