I have an iAqualLink connected to my Z4 pool only panel and use both the phone app and the web control via both internet explorer and chrome on windows 7 and 8. Recently I called tech support for an unrelated problem I was having with my panel and the tech was able to see all my schedules and manipulate them. When I asked him about it he said he thought it is available via the web interface on a PC only. I did not have time during the call to investigate further and the tech I was talking to was a hardware guy and unsure about the web connection and how it is supposed to work. I have never been able to access schedules, I can only turn devices on/off and see status. I had had thought that it was just a limitation of the Z4 since I don't have an RS or a PDA. I have been all over the web interface and I don't see a button for scheduling when I click on my pool it opens in a separate window and part of the secure link has the word "mobile" in it. This leads me to believe that even though I am on a PC I am somehow getting the striped down mobile version of the controls. I have tried several computers with several browsers same result. I can call tech support back and see what they say but I figured I would ask here before doing that in case it is a known issue if not I will give them a call and report back what they say.
