Local Outputs TabPage 34 of 84 eZV-440 Application GuideEdition 2.6Setting Up a Fan OutputThis topic describes how to set up fan outputs on the Local Outputs tab of the enteliZONEconfiguration page.The enteliZONE controllers support up to 3 fan stages (Fan1, Fan2 and Fan3). Typically a 3-speedfan stages uses Fan1, Fan2 and Fan3, and an ECM (Electronically Commutated Motor) fan usesFan1.For more information about the enteliZONE algorithm's sequence of operations, go to theSequence of Operations topic.Set Up a Fan Output1. In the Function field, select the option that applies to your setup:Function Select this option if you are:SeriesFan_ Setting up a series fan in a single duct VAV.ParallelFan_ Setting up a parallel fan in a single duct VAV.ExhaustFan_ Setting up a exhaust fan based on occupancy.For a list of output configuration software objects that correspond to each function, see theOutput Configuration Objects topic.2. In the Stage field, select the corresponding fan stage for the output device. If you are usingORCAview,select the heat stage in the Output Stage field.Start a new line for every additional fan stage.The ExhaustFan function defaults to OccInterlock or occupancy interlock.3. In the Control Type field, select the method of control used on the output device signal.The control types available in the drop-down list will change depending on the option thatwas selected in the Function field and the physical output used to connect to the outputdevice. For more information about control types, see the Control Types topic.ECM fans may require both an analog speed and a binary stop/start signal. For example, fora modulating series VAV fan sequence that has both an analog speed and binary stop/startsignal, this is how you should set it up:Function Output Stage Control TypeStart/Stop Output Series Fan_ Fan1_ BinarySpeed Output Series Fan_ Fan1_ Analog4. In the Action field, choose between direct or reverse control.
