You have 3 interior units?

Yes, But I want those units to be served with only 1 compressor.

Maybe you should consider to model the system like a VRF.

if you have a system with an outdoor unit that feeds three indoor units, it’s a typical VRF system. You can find this kind of system in the HVAC tab on Opentudio.
