Unclear controls exposed #56

Hi, I have connected a board to ARNU36GBGA2 duct unit, in parallel with PREMTB001 controller set to slave mode. The unit seems to work, but I don't understand the HA exposed controls for Fan Speed.

I have an option to modify the 3 values (low, medium, high see screenshot), but what do these values represent?

Here are the C9 and CA codes [15:46:48][D][lg-controller:943]: received C9.12.EB.5C.26.32.00.84.13.00.00.00.44 (13) [15:46:48][D][lg-controller:943]: received CA.00.00.00.64.00.00.00.00.02.F1.01.77 (13)

Another observation - there is an option to set Fan speed to Auto mode via Sub-Function button, but auto fan is not available HA UI

These correspond to the ESP Value installer setting (installer setting 3). It lets you adjust the fan speed for the Low/Medium/High fan modes.

I clarified this a bit in the README. Does that answer your question?
