The selection options for Supply Fan are:
-
Single Speed: This option creates a State Generator, Output Controller, and Output to manage the Fan.
-
Three Speed: This option creates a State Generator, Output Controller, and three Outputs to manage the low, medium, and high fan speeds. This selection enables the selection for the Fan Speed Adjust option under the Zone Sensors (FC) selection, which is an optional interface for specific Network Sensor models.
-
Variable Speed: This option creates a State Generator and Output Controller to manage both a Binary Output to stop/start the fan and a Proportional Output to vary the speed. If you select the Variable Speed Supply Fan selection, only Proportional Heating and Cooling Coils are available for selection.
-
Fan Control by Others: This option assumes that the supervisory system or local binary switch is directly in control of the fan through a separate hardware interface. This option creates a Fan Controlled By Other Binary Input point for use in conjunction with a State Generator for Fan Control By Others to turn heating and/or cooling output controllers off if the fan is commanded off.
