I have my helios placed in my sump and set to a low- 76 high -79. It seems to start beeping with error e3 which means it's above the right heat temp....what am I supposed to do. It happens usually in the afternoon evening and I live in fl so maybe its getting too warm? What am I supposed to do? Corals and everything seem fine. I check it to my thermometer from Amazon and says what it says
