Ok, I got my Aprilaire via UPS today, and it looks like a very simple installation. Can't wait, but lacking some duct and tubing that I have to pick up.
I do have one question though: There is a transformer supplied, 110v-24vac. The 24vac powers the humidifier.
The dox say to *not* hook the transformer up to the blower fan circuit. Wondering why??? It's a very low draw transformer, and I think that the only time the humidifier should be working is when the hot air blower is blowing, so why not hook it up to the blower circuit so it comes on when the fan does? There are no auxillary contacts supplying 24vac to connect the humidifier to, and I wouldn't want to do that anyway as I don't want the water solinoid open unless the blower is blowing.
They do make an optional "circuit draw" module that senses when the fan is drawing juice, but that just seems like a money maker to me.
Any ideas why I can't just hook this small-draw transformer up to the 110v line to the fan motor?
