Weird air temperature analysis results

Hi, I tried to make simple indoor temperature analysis aaand it seems that something went wrong and I can’t find what. All the zones seems to have quite normal temperature level, around 21 celcius degree but the biggest room named KUCHNIA/SALON (it’s in polish for Kitchen/Living room) drops under 15 for some reason. For KOMUNIKACJA zone it is even weirder. It drops under 15 degrees but between certain hours it suddenly is stable around 21 through the year. I’ve attached some screenshots and gh file below.

Ok, I kinda solved it. The issue was caused by schedule component. When I unhooked predefinied heating and cooling set point component the temperature analisys seem to work now. I still don’t know why it behaves like that but I can get along with it for now.
