OK, my first post to this so i hope i'm doing it correctly. I have a Jandy PDA system on the pool that is controlled by the handheld remote. I do not have an aqualink control inside the house, but i can control everything fine with the remote, however, this is the crazy part. When the sun is at it's highest point and it's hot outside i loose all control with the handheld, until the sun gets lower...go figure. I have tried moving the antenna to a different location and that did not help. It only does this in the summer, not in the winter....ie, different sun location i guess. Has anyone else had this problem and what did you do to solve it? Thanks for the help
