Another possible issue with getting a different model chiller (aside from needing to change the communication section of the LabVIEW code) would be if this is considered a pressure system and so would need DA approval to swap to something different. It could very well be an exempt system due to the total stored energy, but that?s not something I?m sure on. This is why swapping like-for-like is always the best way to go when possible.
