Hello All..
I am working on the live project of the Institute building using Energy
Plus Software.The building have the three Floors(G+2) with total 48
Conditioned Zone. In this building I want to apply the VRF system.For that
i am facing the problem of connecting the Terminal Unit to the
condenser.The software shows the following comment-

** Severe **ZoneHVAC:TerminalUnit:VariableRefrigerantFlow "TU21"
** ~~~ ** ... when checking COIL:Cooling:DX:VariableRefrigerantFlow
"TU21 VRF DX COOLING COIL"
** ~~~ ** ... terminal unit not connected to condenser.
** ~~~ ** ... check that terminal unit is specified in a terminal
unit list object.
** ~~~ ** ... also check that the terminal unit list name is
specified in an AirConditioner:VariableRefrigerantFlow object.

In the Variable Refrigerant Flow Equipment option the Zone terminal unit
List have the limitation of feeding only 20 names and I also want to
introduce rest of the terminal Units to the VRF Segment. Please suggest me
how can i add the other Terminal Units to the VRF segment.

All suggestions are appreciated.
