EVD/EVO 24VAC Expansion Board

EVD/EVO board used in many high-end HVAC marine air conditioners.  This expansion board communicates with the main board (PCO).  Connected to the EVD is typically electronic expansion valves (EEV), sensors and transducers for one chiller stage.  Screen not included.  24VAC, Modbus,   

Installation Tips: The stage number of the EVD must be programmed using a screen.  Most system have one shared screen.  If your system does not have a screen, we can set the stage number before shipping.  We also have a screens available (part number 20-2005). The PCO will take care of the rest of the settings as it syncs.  Syncing is done from the PCO.  Find the settings to turn the EVD off then back on.  In some cases there may also be a setting to indicate whether or not you have electronic expansion valves (EEV) connected to the EVD.  This board must also be grounded using the grounding terminal with a piece of paper stuck to it.  Remember, we are the experts.  Email us if any questions.
