In heating systems, a proportional controller adjusts the:

• On/off state

• Output continuously

• Temperature set point

• Time schedule

The main purpose of a D.O.L starter is to:

• Reduce starting current

• Increase starting current

• Provide variable speed control

• Protect the motor from overload

The inverse cosine law is used in lighting design to:

• Calculate power consumption

• Determine illuminance levels

• Measure light color

• Control light intensity
