If Pipe Freeze Pro is Self-Regulating, why is there a thermostat?


The Thermostat keeps the heat cable turned off (and thus draw no power) until it detects temperatures below 37ºF. 

Once it turns on, the self-regulating aspect takes over and directs heat to the area(s) of the cable that are in contact with the cold. The thermostat should be positioned outside of the insulating layer so it can effectively read the temperature of the air.
