Hello everyone, I hear different opinions about this. How is it with the ventilation system in summer, turn it off or leave it on? I have noticed in the last few days when it was warm outside that the heat also came in through the ventilation system. The supply air was already at 24 degrees with outside temperatures of about 28 degrees, no wonder the house gets warm then. How do you do it?
