Hello everyone,
We have been living in our new home with a central ventilation system for just over a year now and are very satisfied so far.
The only issue is the temperature in the attic bedroom (north-east side) in the evening, which is not very comfortable. The room is not even facing south, yet the temperature reaches about 23°C (73°F) in the evening, even though we open the windows wide in the morning to ventilate with cool air and then close the curtains completely.
I suspect that the ventilation system continuously blows warm air from outside (logically) into the bedroom, causing the warm air to accumulate there.
How do you handle this? Is there anything specific to consider?
My ventilation system has been running at level 2 for several months now because I felt the air in the room was fresher, especially during winter. Maybe I could lower it again during summer?
Is there anything else that can be adjusted to improve the situation? Or is the only option to open everything wide for half an hour before going to bed to ventilate again?
I appreciate any advice, tips, or tricks.

If it has different modes but does NOT switch automatically, that could be the reason.The bypass mode with summer day detection is included. However, it should be adjusted accordingly for summer and winter since this setting depends on the outdoor temperature.
I have now changed it from 23°C (73°F) to 18°C (64°F) so that at cooler temperatures the air is introduced directly without going through the heat exchanger.
Let's see if this helps at all.

HeimatBauer14 Jun 2023 13:29The attic is simply warmer in the summer. For me, it improved after the photovoltaic system was installed. 23°C (73°F) in summer is really a good value; getting lower than that is only possible through cooling.

It got better for me once the photovoltaic system was installed. 23°C (73°F) in summer is really a good value; to get lower, you’d need cooling.We specifically chose a concrete ceiling instead of a wooden beam ceiling. It definitely provides a lot of insulation... However, I don’t have a reference from other houses. But yes... 23°C (73°F) is probably still quite good.

HeimatBauer14 Jun 2023 13:50The concrete ceiling only shields against what comes from above. People generate heat, and warmth rises upwards. Bedrooms in the attic should have air conditioning, even if it is just through a dual-source heat pump.
