I am in the middle of a similar build that also uses the Auber SYL-2352 and can't find a good list of settings either. This is what I have gathered from other threads, but I have the feeling that this isn't a complete list:
Run "autotune" using water that is within 10 degrees of your expected normal mash temp.
Pv: current temp of probe
Sv: desired temp of probe
Pb: temp offset - used to calibrate the temp probe + For each degree your probe measures too high, use -1, -2, etc - and vice-versa
Alm1: Temperature alarm - sounds if you get too hot
Are these the only settings that I need to change and are these settings correct for a 1500w RIMS tube with pump?
