All Network Inputs with a -EN name are always paired with an Availability type State Generation module. These inputs drive a state condition in their paired State Generation module that is captured in the State Selection Table.
The primary use of the Enable modules is to allow system-wide logic to determine if the Central Heating and Cooling Central Plants are providing Hot or Chilled Water to the devices. For example, if the HTG-EN Network Input is set to a False state, the Box Heating is Available Pass Through State Generation module does not allow the Heating Valve to open on a VAV Box.
The following table describes the Enable Network Input modules and lists the applications in which they are used.
