Winland TA-40 Fixed Temperature Switch

The Winland TA-40 fixed temperature switch is awesome for people who want their alarm systems to help protect against freezing in their homes or businesses. Have you ever taken a winter get-a-way and come back to frozen water pipes that have burst because it was too cold? Not anymore with the TA-40!

Use this in conjunction with an alarm system and have your panel call you when the temperature falls below 39F (4C). If you have thermostats then the TA-40 should be mounted near these.
