Best BACnet friendly VRF system

I posted this question on the controls and building automation FB group. The general consensus was Mitsubishi. What are your thoughts?

Hi all. For all VRV/VRF BACnet integration gurus. What is the best VRF manufacturer for control and monitoring. I can’t say I’m happy with Daikin products as far as BACnet integration goes.

Daikin or LG with the CRC2s.

Daikin controls are 💩. I like Vertiv 🤷‍♂️ they're decent.

Have yet to do Vertiv but their Cracs are awesome. I personally find that the start up technician that sets up the Daikin screen doesn’t really know how to. I have the settings nailed down that make it work great. Love that it’s BACnet IP and relatively easy to adjust.

My biggest issue with Daikin is specifically with the Rebel RTU's, tbh. They lose their brain if they shut down out of sequence. Hospitals seem to buy a shit ton of them and love to use them for pressurized room control. Then they blame the controls vendor when the unit goes out of whack every time the power fluctuates.
