You're spot on. With that Multiplex system in the Isata 5, some of the lights are turned on by hitting the button a few time to essentially "scroll" through the different ones. This is the case with the awning and patio lights. One click is for the patio light, two clicks for the patio and awning lights, three clicks for just the awning and four clicks to turn it all back off again.
It may sound like a hassle but it really handy when you get to use to it and really doesn't take that much time. It also requires one less button on the control panel, saving space.
