So I picked up a reefkeeper , played with it till I thought I understood how to program it ( didn't seem that hard ) All I want it to do right now is control tank temp . So I should be able to go in alarms , program the set point have it trip to off when temp exceeds 78 . simple right ? Then why does it not shut off the PC4 socket #1 which I have my heaters plugged in to ? Need help with this asap as I can't leave here till I know its working . or I'll have boiled fish and corals
