I have an apex jr. and the temp probe is in the sump. The temp on the display constantly fluctuates rapidly all within the same degree range. Example: it will say 77.6 then 77.8 then 77.5 all within a few seconds. My program is set to turn heater on at 77 and off at 78. My heater turns on and off a lot throughout the day as you can imagine but i feel that is due to so many temp fluctuations. I bought the unit used and this has been the case since i got it. Anyone have any ideas? Is the probe bad you think? Any help would be great
