Re: [EnergyPlus_Support] Node Connection error



The error message is incorrect.  It should read "Sensor node did not find a 
matching node of appropriate type (node type *other than* Actuator, Sensor, 
OutsideAir)."  But there is an error in the node names.  Whenever there are 
node connection errors, the first step to solving the problem is to search the 
input file for the node name listed in the error message.  Start with the 
CONTROLLED ZONE EQUIPMENT CONFIGURATION object for this zone.  There should be 
a node list for zone inlet node with 2 nodes listed, one which is the outlet 
from the unit ventilator and one which is the outlet from the DOAS terminal 
unit.  Make sure the node names match.  The SET POINT MANAGER:SINGLE ZONE 
COOLING object must also reference the zone inlet node name that matches the 
DOAS terminl unit.   Each problem you fix should get rid of two or more node 
conneciton errors.
