I have a question about a problem with heat pump Hitachi RAS/RAC E10H2 . I'm not sure you know the model because it's not common in the USA.
So , the air -conditioner has 5 indoor fan speeds but actually they're 3. I'm wondering if it is technical problem or it's just supposed to work in a way like that.
I'm thinking to install potentiometer between the motor and the plug. But i don't know which cable of the plug is for and thus I need your help. The cables are red , black , white , yellow, blue.
I have photos of the plug and the wiring diagram but I can't post them here

I will really appreciate your help
