Entering the screed after three days or already the next day?

Our screed layer said back then that I should keep the windows tilted open all the time. Screed heating was from the end of October to the beginning of December... I didn't do that, but ventilated by opening the windows fully three times a day. When I see other houses built by the same construction company, they apparently kept the windows tilted open. So much for the topic: Listen to the screed layer..
