Hi All,

I have a question about creating a system. I have VRV units for the zones
and I have %100 fresh air handling unit with Heat recovery device in it.
Fresh air air handling unit have heating coil and also have cooling coil.
Heating coil is supplied by LTHW which is coming from natural gas boilers.
Cooling coil using air cooled DX outdoor unit for cooling. In that case, how
do I have to create the air handling unit ? By the way, fresh air handling
unit serves to all building, I mean I have just one ahu.

You can see a red zone which have vrv units, fresh air and return air
(coming from the air handling unit) in it. Is it something from this
screen???

Thanks for your support
