I have one of these in my house in the laundry room and we had an electrical issue and had the electricians come out I asked him why the switch to the fan wouldn't turn it on and off and they said it was always supposed to stay on. The builder told me it was supposed to always stay on for mold mildew and moisture control.. seemed a little strange to me for a fan to always stay on. Does this sound correct? Or am I getting bullshitted
Nope, you are not being bullshitted. Modern construction techniques require air flow ( buildings ar built tight) so leaving the fan running will save you a mould clean-up down the road.
This looks like a great fan, but I have to ask... If you've been running your fan for 10 solid years continuously, even at the "low" 50 cfm setting, that's over 26 million cubic feet of heated/conditioned air that you blew outside. How much does it cost to condition 26 million cubic feet of air? Yikes.
Blowing heated/air conditioned air outside is a good thing when you consider the fan will also draw in an equal amount of fresh air (open windows, doors etc.) Its a small price to pay for your health. The air that these blowers typically remove is from bathrooms, basements, laundry etc. that can have high levels of humidity which can be harmful to your home and your health. 26 million cubic feet of air isn't as large a number as as it sounds. ;-)
This is a legitimate concern! Though, two things: 1. You breathe a TON of air every day. Do you wanna breathe same air again and again? 2. Energy Recovery Ventilators solve this problem. Why they're not the norm everywhere, I don't know.
I know this is an old video, but...can anyone tell me how the fan speed is adjusted on the fly. The video suggest a motion sensors takes it from 50 CFM to ~100CFM. The manual I read shows this setting as a dip switch - nothing than can be automated. Any help would be apprecitated.
