Comments about 10" Round Motorized Damper by Jackson Systems D-10:
We bought this damper to replace one our guest bedroom zone. The damper arrived promptly, in fact sooner than expected. Installation instructions were fine except for one thing. The flathead screw that you use to adjust the amount of air that is dumped through the damper when it is closed, had come out, so we were totally confused about that until we found the screw in the shipping carton. The two wires on the damper motor were not marked to indicate which was the hot one. However, we guessed it was the one with the most writing visible on it, hooked it up that way, and it worked. So either that was the hot wire, or it doesn't matter and would work either way. The entire installation took 1-1/2 hours, including carrying all the tools and other stuff back to the guest bedroom zone in the rafters, where our ducts are located, cutting the insulation, wiring up and testing the new damper to make sure it closed and opened, removing the old damper, inserting the new damper into the two reducers that were already there for the old damper, screwing the damper to the reducer, taping the damper to both reducers, and taping the insulation back around the whole thing. The easiest part of this whole process was hooking up and installing the Jackson D10 damper. Assuming it continues to work well and hopefully lasts longer than the four years our last damper in this zone worked, we will buy this product again the next time we need a damper.
