Hello, I live in a new build flat with MVHR (Vent-Axia). The system seems to work well and I have no reason to believe it wasn't commissioned properly. However, I do get more condensation in my bathroom than I would like. The system is set up so that boost mode starts when I turn the bathroom lights on. The current settings are: Normal Extract 20%, Normal Supply 20%, Boost Extract 30%, Boost Supply 37%. So my questions are: 1) Is it safe to increase the Boost Extract % (I know how to do it)? 2) If I do that, do I also need to increase the Boost Supply rate? By the way, I'm not concerned about extra noise or power consumption. Even in boost mode I can't hear the ventilation at all (although it is running). Any insights appreciated – thanks in advance.
