You can rig most (if not all) industry-standard blowers to run whenever, at whatever speed, you want them to, rather easily. Granted, a dimmer switch isn't quite as efficient as an ECM control, but 75 Watts is still less than 750 Watts. So what if I lose 15 RPM in translation?
Don't tell my landlord, but I tied into the LOW speed wire that the furnace manufacturer had no spot for on their control board. It was just begging me to be connected to something. I couldn't just ignore it, now, could I?
