Midea KJR-120C/TF-E wall controller: a fixed wall control for your mini split.
A wired controller, connected by cable to the indoor unit. For a cassette or a ducted unit hidden in the ceiling, a shop, a rental, or to replace a broken wall controller. We check your unit’s model before ordering it.
Wired controllerKJR-120C/TF-E
A fixed wall control, wired to the indoor unit.
We check compatibility with your indoor unit model before ordering.
A remote gets lost. A wall controller stays put.
The KJR-120C/TF-E sends the indoor unit the settings it can carry out: modes and speeds vary from model to model. It is not a programmable thermostat.
A cassette or ducted unit in the ceiling is easier to control from a fixed point on the wall.
The control stays in place and staff find it easily.
No remote to replace at every tenant change.
When the existing wall controller stops working or was damaged during work.
Four paths for the same setpoint.

Three questions, one suggestion.
Answer, and we tell you where to start. We always confirm with your unit’s exact model.
1. Is your indoor unit in sight?
2. Do you want to control it from your phone?
3. Do you have a 24 V thermostat you want to keep?
Answer the three questions.
The suggestion shows here once all three answers are in.
A Midea 24 V interface
Midea offers the 24 V Mini interface and the 24 V Full Function kit to keep a 24 V thermostat. Compatibility depends on the model: we check it before ordering.
Have my model checkedWi-Fi and the SmartHome app
The Midea SmartHome app controls the unit from anywhere, and works with Alexa and Google Home, according to Midea. The Wi-Fi module is optional depending on the model: we check yours.

Fixed on the wall, wired: the right control when the unit is hidden. It is not programmable and has no Wi-Fi.
See the controllerThe included remote is enough
Your unit is in sight: the infrared remote does the job. A wall controller still helps in a rental or a shop, where a remote gets lost.

Midea indoor-unit brochures (1-way and 4-way cassettes, low- and high-static ducted, floor-ceiling, console): “Old Unit Replacement” and “Outdoor Unit ONLY Replacement” scenarios. According to Midea, when both units are replaced, the existing piping, wiring and 24 V thermostat can be used (with the 24 V Mini interface or the 24 V Full Function kit), and the indoor unit’s air outlet must be adapted to the model’s size. We check the condition and compatibility of each part at the visit.
