爱尔兰采购需求：洁净室设计、洁净室服务、洁净室产品

I'm reaching out regarding an issue I'm facing with my recently installed unit. It seems to be stuck in heating mode and I can't figure out how to switch it to cooling mode. I've checked the app but haven't found any clear settings that relate to this. Could you provide detailed instructions on how to adjust the settings, either through the app or the touch screen? I want to ensure that I'm not missing anything and that I can fully utilize the features of my unit. Your assistance with this would be greatly appreciated.
