I got the BWDM retrofit a month or two ago. When I tried it today it was not significantly louder than my normal A/C. I checked the fan speed via the left scroll wheel and it was at low with BWDM enabled.
I'm fine with having to adjust the fan speed manually but I wonder if the cool BWDM button on the screen actually does anything.
