My pool and system are about 8 years old. I have a Jandy Lite2 heater and Jandy Aquapure 1400 SWCG. The Lite2 is used to control the pump and (obviously) to control temperature. I would like to be able to remotely control the heater to turn it on or off, adjust the temperature or adjust the timer, ideally from an iOS app or a web UI. It would also be nice to be able to control the SWCG from the app/web.
What do I need to do this? I believe that Jandy (AKA Zodia) sells something called the Aqualink Z4. But there are several models - which one do I need? I am guessing the ZQ-4PI. Will they work with my system and what all can I control with this?
How hard are they to install?
I see them listed for prices from $650-$1000. And why are they so darned expensive? This isn't rocket science in 2015.
