Hi Heatvex and welcome to the forum!
First and foremost: not an expert here, so beware :)
My guess is that your Genvex is only for ventilation, not for heating (or cooling for that matter, it is not aircon) so you cannot control the temperature in the apartment with it. it only ventilates and uses a heat exchanger for reclaiming heat.
Supply: is the air being blown into the apartment
Room: is the temperature where the control panel is located
Fresh air: is the air being sucked in from the outside
Exhaust: is the air being pushed out
Extraction: is the air being sucked out of your apartment
All temperature readings except the “Room” is measured in the ventilation unit.
So it sucks in 15c air, pushes it through the heat exchanger where it meets the warm air from your apartment and gets heated to 21c that is then pushed into your apartment. This does not cool things very much.
Some units have an option for a by-pass, so the fresh air bypasses the heat exchanger, might want to look for that in the menu. To figure out what your unit is capable of you need to find the model of that and not just the control panel (Optima251).
So my guess: it works as intended. With vest facing (maybe big) windows and a modern insulation standard things get hot. I have turned off our heating a month ago and we also struggle with heat. We often reach 30c during summer and I have a by-pass which helps a lot!

Hi Mads, thanks for the quick reply. It does have a bypass function, which shows as 100% all the time (since my desired temperature is far, far from those damn hot 25 degrees). As you guessed, the apartment is almost all glass (big mistake #1 for me) and West-facing (mistake #2). At the evening, when the sun hits, this gets like a sauna honestly. Not even having the windows open cools it down.
Now it's 12 degrees outside (went out with a t-shirt and felt coldish), when I get back in, I can tell the difference (that sauna effect), of course to a much lower degree than at the eveining. It leads me to believe there's gotta be something heating the apartment other than the apartment iself and stuff like fridge/computers/our bodies, etc. There's an office downstairs so I'm wondering if that may have something to do.
Anyway, even with bypass 100% on I can barely feel a cool breeze going in. The apartment has 3 rooms + living room (each one with 1 blower) and 2 bathrooms (each with 1 exhaust). I'm leaning towards shutting it down and checking if the filters have actually been cleaned. But other than that, I'm wondering how to see if the bypass is working properly (read some threads here where the mechanism got stuck!).
Any other suggestions are appreciated. I've already ordered better curtains to try to "repel" the sun, and got a fan from amazon (those smaller "table fans" which remote control, etc)
