If you mean the heat cables to keep ice and snow melted, No. The cable just plugs into an outlet and the cable stays warm all season long.
No, Mark. They are self contained, and only need power.

Hi Mark! Perhaps this will give you a bit more information. Good luck to you. Thanks for your question.
Heat tape has a built in, and extremely basic, Thermostat. If you read the packaging for your cables, it will tell you the temperature cutin/cutout ranges for your cables.
Hi Mark, hope this video answers your question
