Question about Bosch Hausgeräte Split air conditioner CL3000i35E outdoor unit

If I understand correctly, this only refers to the outdoor unit (according to the answer to daniella73's question). If this is indeed the case, I don't quite understand the point. What am I supposed to do with an outdoor unit alone? Especially as I have not seen any possibility of purchasing the indoor unit separately. Or am I missing something? I'm also a little confused by product images 1 + 5, which show two appliances. In my opinion, one is the indoor unit and the other is the outdoor unit. Is it a complete split system after all and not just the outdoor unit? Questions about questions..... The product information and specifications don't really give much information either, as they are incomplete. Would be very grateful if the person responsible for the product could provide some feedback. If I'm in the wrong place with my post, please bear with me. It's my first time ;-)
