GREE thermostats and wall controllers. Nine controls, and not one that fits everything. Which one does GREE name for yours, and how far can the cable run?

9 GREE controls on this page, from a wall unit’s controller to a building’s. The right controller depends on the system: a wall unit, a cassette, a duct or a GMV do not take the same ones. And the cable rule changes depending on whether the document is American or Canadian.

The right controller

Pick your system. GREE says which one goes with it.

Fourteen pairings taken from GREE Canada brochures, Dettson drawings, manuals and GREE Comfort submittals. US series model numbers do not match Canadian ones: they are listed separately, last.

Which controller for which system?

Each answer gives the controller, whether it is included or optional, the cable rule and the document. Systems sold in Canada come first; US series are marked “USA”.

All nine side by side

What each control does, and the document that says so.

Eight wall controllers and one adapter. GREE Comfort’s US sheets and the Canadian manuals do not always agree; where they differ, both values are shown.

AirGreen × GREE

GREE designs each controller for specific units. AirGreen reads the model number, picks the control GREE names and runs the cable within the document’s limits.

All 9 GREE controls, right below.

Each product page carries the controller’s name. To know which one fits your unit, use the tool at the top; for their differences, the table of all nine.

Technician’s corner

Static pressure, the Extreme brochure, the terminals: what the installer checks.

The XE71 and static pressure

The XE71 submittal says it cannot set static pressure on DUCT B ducts and points to the XK76 or XK19. GREE Comfort’s compatibility guide has a note on the controllers that can, without it being readable which ones. We follow the XE71 submittal.

XE71 submittal · compatibility guide, note 2

The Extreme wall unit

For its wired thermostat, GREE Canada’s 062024 brochure prints XE-41 in the English version and XE-71 (optional) in the French one. Same document, two answers: the unit’s model number decides.

The ME34-44/G, terminal by terminal

O/B for the reversing valve, G for the fan, W for heating or the electric element, Y for the compressor, G1 to G3 for three fan speeds. If the thermostat also runs a gas or oil furnace, that side goes to a licensed partner.

PVC-sheathed cord of 2 × 0.75 to 2 × 1.25 mm², 250 m at most for the whole communication line. One master (address 01) and one slave (address 02) on the same units.

LogisVert · Hydro-Québec

LogisVert pays for the heat pump, not the control.

No amount for a controller

The LogisVert amount is calculated on the heat pump’s heating capacity at −8 °C, AHRI number by AHRI number. A controller or an adapter has no AHRI number: it is not on Hydro-Québec’s list of Oct. 27, 2026. System amounts are on their own pages, for example GREE multi-zone.

Questions

Nest, Wi-Fi, distance: what people ask us about GREE controls.

Which controller goes with my GREE unit?
It depends on the line: XE72-44/E on All Match R32 high-static ducts and cassettes, XK76 on the Free Match R32 and the 8-way cassette, XE-71 or XK-19 on the R410A Free Match units. Give us the indoor unit’s model number: we will tell you which one GREE names.
Can I keep my Nest thermostat?
On a ductless GREE unit, through the ME34-44/G adapter: GREE gives Nest as an example of a 24 VAC thermostat. On a UNIX R32 central system, the GREE documents differ: GREE Canada’s brochure says it works with most 24 V wired thermostats, manual X40273A requires the WK-010WC1. We check yours at the visit.
Which one has a weekly schedule?
The XK76: 7 days, 8 segments a day, for wall units and the Free Match R32. On a GMV, the XE70-33/H: 7 days, up to 4 schedules.
Which one works from a phone?
The XE72-44/E: its manual says the GREE+ app can run it. GREE Comfort also presents an “XE72” as the Wi-Fi controller for A and B series cassettes, floor/ceiling units and slim ducts; no document says it is the same model.
How far from the unit can the controller go?
It depends on the document: 26 ft of harness for GREE Comfort’s controllers, up to 20 m (8 m as standard) per the Canadian XE72-44/E and XE71-44/G manuals, and 250 m of line in total for a GMV’s XK46.
Can an XE71 replace my XK19?
Yes per GREE Comfort’s compatibility guide, provided the harness is replaced too. We first check that your unit is among those the XE71 submittal names.
