Nest compatibility with Mitsubishi?

[MMMoul]

I've got a Nest  Learning Thermostat installed with my current heating and AC system, and it works well.

My AC condenser and furnace now need to be replaced, and I am thinking of upgrading to a Mitsubishi PUZ-AF2NKA7-BS 3.5 ton heat pump air conditioning condensing unit.  This will also require the install of a Mitsubishi PVAA42AA7 heat pump indoor air handler.

I'd appreciate it if someone can confirm whether that new unit will be compatible with my Nest Learning Thermostat?  Thanks.

It looks like that system uses a proprietary 2-wire interface which is not compatible with any of the Nest thermostats.

Hey folks,

Thanks for being here in the Google Nest Community Forum.

As what Patrick_Caezza has mentioned, if that HVAC unit is using only 2 wire configurations and possibly be a proprietary type of system, it is not compatible with Google Nest Thermostat. 

Thanks for always helping out, Patrick.

Proprietary systems are not compatible with Google Nest thermostats. However, some proprietary systems can be rewired by a pro installer to be compatible.
