H1 & H2 Wires Only On Thermostat Control Unit

Jackson25294 — Thu, 29 Dec 2022 00:51:22 GMT

I currently have a Gree XE71-42/G Wired Controller which only has a H1 and H2 option for wires. How do I connect this type of wiring to any of the nest models? What Letters do these run to on the distribution plate for the nest thermostat?

You cannot use a Nest with mini split systems unless Gree makes some type of interface device.

You could try to contact Gree to see if they have something to make a Nest work with the model number on the side of the head unit.

That Gree controller is special device that can control the swing and other functions of the mini split.

The Nest has no way to control those functions on a mini split.
