Electrolux Pure A9 switching to manual ignores fan setting

[quattromic]

Describe The Bug:
When a scene is run, that shall put Electrolux Pure device from AUTOMATIC to MANUAL work mode with specific Fan Speed, the fan speed gets sporadically not set successfully.

To Reproduce:

1. in Homekit (e.g. Eve App) create a scene with action for Electrolux Pure device
2. define Work Mode -> MANUAL and Fan Speed -> 65 %
3. (manually) set Electrolux Pure device to work mode AUTOMATIC (a.k.a. smart mode)
4. run scene

Expected behavior:

• Electrolux Pure device switches to MANUAL with Fan Speed = 65 %.

Observed behavior:

• Electrolux Pure device switches to MANUAL. But Fan Speed = 65 % is sporadically not accepted/set.
• Subsequent execution of same scene (Work Mode == MANUAL) correctly sets Fan Speed.
