Can't calibrate my heater
I've attempted to recalibrate my heater several times and can't get it to the temp i want it at. It has two dials. One has the numbers on it and it's blue and the other is on top of the blue one that's a red arrow. The temp is at 72.5 but I want it at 77. I have it set for 77 but stays at 72. I can move both dials and my directions are unclear so I'm not sure what to do.
