Serounder Replacement Remote Control Controller for Gree Air-Conditioning Yt1f Yt1ff Yt1f1 Yt1f2 Yt1f3 Yt

All YT1F controllers (including YT1FF) are the same. The one with 2 F's just has a few more features that most AC's never use anyway. The big question everyone has is How to change from C to F?Found it: YMGI Symphony Solo (58) & Choir (59) Series Remote Control Tutorial Videopress the MODE and - buttons simultaneously while the unit is turned OFF.The controller works just like the original that came with my AC, no problems.

After reading the reviews, I ordered this remote to replace the original, which stopped working. It will turn the unit off and on, change the temp, etc. but only in Celsius. The solution was to "turn the unit off, press 'mode' and '-' buttons at the same time" did not work. Nothing worked to convert to Fahrenheit. This is for a guest house, and cannot be used.

Would only work in Celsius and would not change to Fahrenheit. We tried every tutorial and settings instructions we had. It wouldn't change over.

The remote will not turn on a Lennox mini split AC. It is a cheap copy of the original remote - lighter with differences in the case and lettering. The liquid crystal display is also defective - it displays a mix of numbers and nonsensical characters that flash on and off at random.

This controller is in Centigrade. I can't believe this would be shipped in the United States. I saw nothing about that in the description. I could not figure out a way to change it to Fahrenheit - no directions.
