VAV devices traditionally provide a variable flow rate to the space, this is not always the case there may be other reasons why a VAV device may be more suitable. 1 3. A system and method including the ability of a building automation system controller to automatically determine which VAV boxes are physically associated with which air sources in a building or facility with multiple air sources by coordinating the individual or simultaneous manipulation of the fan speed of the air sources or the VAV damper. Historically, heat-er elements placed downstream of a VAV damper have experienced two major problems: • Elements fail prematurely due to hot spots resulting standard single duct VAV equipment. This is the most basic type of VAV box. This means that there is only one solution for a given gpm, # of rows and airflow rate, for a given coil size. VVT systems maintain a bypass between the supply and return ducts to the unit, meaning that the fan runs full tilt regardless of whether the VVT boxes are fully open or averaging 20% open. (The interiors may also require zone dampers for static pressure control). g. The board is factory programmed to Control the Motor in either Fixed Speed mode or Proportional Control using a remote 2 10 V DC input signal. CVM03050 controllers operate on an RS-485 BACnet MS/TP bus as BACnet Advanced Application Controllers (B-AACs), and integrate into Johnson Controls and third-party BACnet systems. When selecting a coil, one can pick only one independent variable, with different parameters for increasingConvert the VAV box into a static pressure/pressure independence station by controlling it with a static pressure signal from the duct 2/3 to 3/4 between the takeoff for the first Therma-Fuser diffuser and the takeoff for the last Therma-Fuser diffuser. A typical configuration for VAV would be to set the blower to hit a fixed static pressure target (say, 1 to 1.
