Have a spair heater hooked up set 2 degrees lower then the apex just incase it switches off. And have your heaters set no more then 84 so if it switches on all the time it will not boil your water. And after you have it all setup the way you like it make a backup just in case. There are a few tricks, to check it from anywhere with your iPhone you have to dmz the ip of the apex. And forward the port then you can view it from anywhere! Aslong as you have your ip address
