This controller worked for a failed green board on a glycol machine only had to adjust a few settings one was set point (mid point) 2nd was the alp hysterius setting and 3rd was the alp low alarm setting. it functions as described on a 115volt unit. the ssr is a quality built low/high volt relay. 12dc/ over 115vac my set point was 15 hysterius was 5....allowing the final refrigeration to be 20 high 10 low.
