The operator has control over several factors in this system.## Step 2The operator can control the direction of airflow in the system. This is done by adjusting the direction of the air vents.## Step 3The operator can also control the velocity of the airflow. This is done by adjusting the speed of the fan in the system.## Step 4The operator can also control the temperature of the system. This is done by adjusting the thermostat, which controls the heating or cooling of the system.## Step 5However, the operator does not have control over the exterior temperature.
