Have a client with a pool house.
Stage one heating done with radiant from geothermal (same as system in house where we currently use, but has geo cooling, too)
Secondary heating and first stage cooling are spec'd to be controlled by a Mitsubishi MSZ/MUZ (MSZ-FE18NA indoor/MUZ-FE18NA outdoor) single-room mini-split heat pump. The unit has an RF remote and optional wired control, but does not use typical Tstat wiring (relays).
Has anyone dealt with controlling this via a Crestron CHV-TSTAT so that the HVAC can be properly staged and controlled (they currently have compteing heating sources.)

We have the option to replace the system with something if we know it can be easily integrated. Anyone use anything like this (18,000 BTU) and can control from Crestron.
Maybe even something that has another form of interface or com port (RS232/485)

Any help would be appreciated.

Some of the Mitsubishi units work with BACnet (which uses RS-485). I've seen the protocol specification or a module on here (if you don't see it, e-mail me), so you may be able to roll-your-own solution. Crestron also has a specific device to interface with BACnet (GLS-BMA).

Thanks, found some of this info out...
It would be awesome to buy a $6K interface controller and $6K BMS for a
$2.5K mini-split, but i dont think even just one of these is a viable
option

This looks pretty interesting. Does anyone have a module or know where to get one?

I am seeing press releases stating they are now an Integrated Partner but can't seem to actually find them listed on Crestrons site.

I will email cool automation now but just wanted to see if anyone has worked with one in the past. Thanks.

I used the Cool Automation for those Mitsubishi units. Works great.... well, works great after I fixed the Crestron module to send the addresses correctly on 3-series.
