This controller sure does make monitoring the pool heat pump and scheduling it for energy efficiency easy. For example, I have it run only Thu-Sun because I don't usually use the pool on weekdays. I can do this both at home, connected to my own WiFi, and when away, which suggests that some of the earlier problems have been resolved.Installation was straightforward, although initial WiFi connection required more than a few tries. The app is telling me that the device's firmware needs to be updated, but I have not yet been successful there.

Easy install. Easy interface. Easy to control our heater.

This thing saves a lot of trips to the pool heater! Great to have ability to control pool temp from anywhere…simple 4 wire hookup and iPhone app was easy to navigate and setup…highly recommend!!! Macke was fantastic with super quick shipping!

The installation was easy. Although I had my electrician do it I watched him and assisted him. Total time to install and mount the unit was less than 39 minutes. The misleading thing is that you can only control the pool heater from within your wifi range. I thought I could, for example be visiting relatives and set  the temperature before heading home. Another issue I found d is that it doesn't seem to find my 5G wifi only the 2.4 which is not a major issue but I have to remember to switch networks on my phone to 2.4. The app is easy to use. An enhancement that would allow you to control the pool heater out of state would be a plus for property owners that rent out their property. The owner could schedule, set Temps, turn unit off and on. Otherwise I'm happy with both the pool heater, module and app.

This great product gave me the ability to connect my phone to my new AquaCal heat pump for the pool. The price was great and instructions very simple to follow.
