Good value for money
Compared to calling a technician for a replacement, buying this online saved me a lot of money. It works flawlessly with my 3HP unit. Deducting one star because the manual could be more detailed.

Restored full functionality
My heat pump was stuck in defrost mode due to a faulty controller. This genuine Midea panel fixed the issue instantly. Temperature control is now precise and responsive.

Perfect replacement for my old unit
This genuine Midea controller fit perfectly on my 5HP heat pump. The installation was straightforward, and the display is much clearer than my previous aftermarket one. Highly recommend buying the original part.

Works great but shipping took a while
The controller itself is excellent quality and functions exactly as expected. My only complaint is that shipping took longer than anticipated, but the product quality makes up for it.

Genuine quality shows
You can tell this is an authentic Midea part. The buttons have a nice tactile feel, and the menu navigation is intuitive. It resolved the error codes I was getting with my generic controller.

Easy to install
I am not very tech-savvy, but I managed to swap this out in about 20 minutes following the manual. The wiring diagram was clear, and the system recognized it immediately.
Q: Can I use this outdoors without additional protection?
A: While the unit is durable, it is recommended to install the controller in a sheltered location or within an electrical enclosure to protect it from direct rain and extreme weather conditions.
Q: Is this controller compatible with a 4HP Midea heat pump?
A: This specific model (KJR-51/BMK-A) is designed specifically for 3HP and 5HP units. For a 4HP system, please consult your unit's manual or contact support to verify compatibility.
Q: Is firmware updateable via USB?
A: No, this model does not support user-initiated firmware updates via USB. Firmware management is handled internally by the main heat pump module.
Q: Does this come with the connecting cable?
A: Yes, the package includes the necessary wired connection cable required to link the panel to the main module.
Q: What should I do if the screen remains blank after installation?
A: Please double-check the polarity of your wiring connections and ensure the power supply to the heat pump module is active. If the issue persists, contact our technical support team.
