Hello

My question relates to system creation when using the air cooled chiller default family. Upon initial creation of the system you have the ability to create a hydronic supply or a hydronic return. If for instance you go ahead and create a hydronic supply system and add a cooling coil and complete the system all is well. But when I go to create the hydronic return system the ability to do so is no longer there when highlighting the chiller. This type of instance does not occur with a boiler, the option still remains. If I go ahead and create Other, I cannot add the coil to the system, as it says it is already assigned.

I then went ahead and said well let me add a pump in between the coil and the chiller on the return side. This time piping it up on the fly, a return system is created between the pump and chiller, but I lose the ability to edit the system between the coil and the pump.

What am I missing here? Thanks.
