Apex Lite & ATO what do I need?

Nope, I trust the Apex with passion! (I just never thought of it.. )

But you will start noticing the evaporation rate difference depends on each day (dry, hot, cold, wet, etc) and if you think its too dry you change the setting from your phone wherever you are, it's the beauty of having remote access!

 

i have the lite and you can add anything to it that you can add to the full apex. i recently added the break out box and added water on floor sensors to my system. with the break out box there are a 5 or 6 i can't remember exactly how many spots to add sensors, so if you added the the sensors for the ato ( personally i have a separate ato and use the apex as a fail safe) if the sensors were added to the apex you would have other sensor spots to program for other uses.
i would recommend using the apex as a fail safe and getting a separate ato though
