I have a Senztek AlphaStat digital thermostat controller. Sensor probe keeps failing in the dry well because moisture build up in the dry well.
I came across your website and interested in ds18b20 waterproof sensor probe. The sensor probe comes with 3 wire connections while my thermostat has 2 wire connection. Which 2 wire from your sensor probe to connect to my thermostat 2 wire connection?
