Hi all, the thermostat on my 1980 Hot Spring Model B stopped functioning so I purchased a new thermostat utilizing the same Watkins/Eaton part number as the original. I hooked up the thermostat the same way but now the thermostat appears to be working backward. One difference between the original part and the new one, despite having the same part number, is the old thermostat only had one electrical pole on the bottom and it looked like Hot Spring cut off the other terminal. The new thermostat has two terminals on the bottom. Any thoughts?
