So as I'm heading to the back of the house I walk past my apex display and notice the help reads 82.5. The temp is set to come on at 77 and shut off at 78. So I quickly check the amps and see it is indeed pulling the amount it does when the heater is on. I then double check with a manual check by touching the heater in the sump and its on. It a titanium heater with only the apex as the control. I then pulled the power supply and reset the apex unit and it shuts off. Now I'm a little freaked out though cause if I hadn't noticed I would have woken up to a dead tank. Why would it stick and has anyone ever had this issue with their apex unit sticking on them? Two years running with it and no issues until today
