ItÂ’s attached to the coil. Current cut in 38*f and cut out 34*f box temp.
Trying to bring her down to 30*f cut out.
is this for the Pepsi cooler ? if it is attached to the coil that would explain the difficulty you are having .... not sure the differential is going to be large enough .....
you are correct, you want to adjust your cut in first .......
for a 32 - 38 degree box, 35 degree beer
unplug cooler, set cut in on dial to 34 degrees, set differential to maximum, plug in cooler, once box hits 34 degrees raise cut in on dial to 42 degrees, adjust differential to minimum, compressor should cut off, adjust differential to maximum, allow box to slowly rise to 38 degrees, as box approaches 38 degrees slowly lower cut in temperature until compressor turns on, as box approaches 32 degrees slowly lower differential until compressor turns off ......
if you want different temperature settings substitute the 32 and 38 for your own numbers ..... if it is for the Pepsi cooler and you want it cold I would run the box between 32 - 38
