DDC-400 De Ice Controller plus the DP-8 controller status panel is a piece of used equipment taken from a Vertex 9M antenna that we sold to a client in the Middle East.
When the de-ice controller was removed from service it was in working condition however, we have no certain way of testing it. Our guarantee of fitness still stands, if the controller fails to meet the buyers needs we will accept a return.
