I’m trying to fix my old Morgan Spa that has a three wire temperature sensor connection (three wire/4 port). It looks much like the connection on the PCB you are showing here. The temperature sensor is not inside the skimmer box, however. I haven’t been able to find a comparable three wire temperature sensor. I thought I found one and ordered it but when it arrived, it was a two wire connection (still had the four port configuration). Any advice? Can I use a two wire thermostat to replace my three wire one?
