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.
