Air Loop Controls/Sensors
Air loop controls and sensors must be applied to the system in order to define the location of temperature and humidity sensors and how the system is controlled. The sensor must be placed in the air path and connected to a component or components that will control the temperature or humidity.
For example, in order to control the temperature at the outlet of a draw through fan, the temperature sensor should be placed in the air path after the fan and the controller should be connected to both the cooling coil and the heating coil.
Temperature Sensor
A temperature controller is required. The temperature sensor is placed on the diagram to measure the temperature at that point in the air path. This controller should be connected to the OA control as well as each of the coils. Some system configurations will require multiple temperature controllers. For example, the dual duct system will require a separate temperature for the cooling coil on the cold deck and heating coil on the hot deck. Different control strategies can be used to maintain the temperature at the desired values. See the Properties for more details.
Humidity Sensor
A humidity controller is optional. The humidity sensor is placed on the diagram to measure the humidity at that point in the air path. Different control strategies can be used to maintain the humidity at the desired values. See the Properties for more details.
