jdavis Posted August 12, 2012 Report Share Posted August 12, 2012 I still have some questions on the limit switches for 94 hot springs soverign. I know one is 120df and one is 150df limits. Does that mean water is maxed at 120df then switch goes off and when water heater maxs at 150df then it goes off. Why wouldn't the 120 limit just shut everything off? Also. Now that I do not have the switches in and am wired direct to circuit board (switches on order but backordered) how hot can the water get before something happens to heater or blows fuses? Thanks. When I keep temp on 4 the breaker does not trip but when I put to level 9 (the highest on dial) the breaker will trip. Thanks. Quote Link to comment Share on other sites More sharing options...
Dr. Spa Posted August 12, 2012 Report Share Posted August 12, 2012 the 120 measures the water in the spa the 150 measures the water inside the heater (to sense if the heater is on, when there's no water flowing through it) At 140 PVC starts melting, and would start leaking, emptying the spa Quote Link to comment Share on other sites More sharing options...
