VIDEO: Installing an AC Coolingstat for temperature control

Here's the thing about that. You can use the same air box along with the module board and t-stat you normally find for ducted system right on the air box, if you can figure out a way to get 12-VDC to the module board.

The same controls work regardless of whether the unit is ducted and a non-ducted air box is available. So if you can find a way to get 12-volts to the air box, everything else will work. However, I am not sure how a T-stat normally found on the wall will look on the ceiling.
