Re: [EnergyPlus_Support] VAV system modeling?
When attempting to fix Node connection errors, the first step is to search the
input file for the node names listed in the error messages. Often, the cause
is a typing error and you will find that the node name appears only once in the
input file. Only zone air node names should appear once. Every (or nearly
every) other node name should appear two or more times in the input.
The first message indicates that "ZONE 25 INLET NODE" has been specified in a
zone splitter or supply plenum object, but has not been used in a terminal unit
object (e.g. DIRECT AIR, SINGLE DUCT:VAV:REHEAT, etc.).
The next error indicates that "ZONE EQUIPMENT INLET NODE" has been used in an
AIR PRIMARY LOOP object, but is not used in a ZONE SPLITTER or SUPPLY PLENUM
object (or directly connected to a zone terminal unit if serving a single
zone).
