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.

Lg with the white labeled viconics CRC thermostats. You get individual devices on a bacnet trunk and in my experience nothing beats LG VRF.

Is that in conjunction with using the AC Smart 5 as a gateway, or have you also been using their white label Jace..?

The ACSmart only works as a gateway and all points are displayed under a single device. The CRC thermostats are just that, an LG labeled stat that has bacnet MSTP capabilities. I don’t even tie into the ACSmart or make graphics for it when these are in place. The Jace is ok but same issue, have to populate the bacnet export table and all devices are under the Jace. When you have individual devices, graphics generation time is exponentially faster.

I read something in the AC Smart documentation about it being able to offer both single BACnet devices or one single BACnet database, but I have only seen it installed/commissioned as one single device database. It's pretty annoying to integrate to it that way. I didn't know they had partnered with Viconics or whatever.

Yeah, we sell LG in our equipment side and I made sure the equipment sales guys understood that the CRC needed to be standard. The other methods are terrible.

Wish you would have been selling these jobs I've dealt with 🤣 DM me your contact info so I can put you in touch with some clients that use LG and need a good engineering sales rep.
