Moin, Moin, now it’s getting warm again and the air conditioning has to hold back. Unfortunately, she doesn’t always want to work with me. There are days when the works great and it comes nice cold out of the ventilation, – then there are days when only warm air comes out of the ventilation. Sometimes this also varies several times a day. Question: Can you please ask your glass balls, what the reason can be? I mean the function basically. Just because the partly also really cold can’t it be an empty facility? Can you give me a tip on what I can do? Thanks and greeting from Hamburg!
