The Thermal Controller is an optional add-on item for the FeelsWarm heating mat. Its function is to lower the temperature of the counter if desired and to turn the unit on/off with a button but it is not necessary to operate the mat.
The thermal controller can be mounted inside of your cabinetry next to your low-voltage transformer. It provides six different temperature settings and an on/off button. (A heating mat without the controller can be turned off by unplugging the transformer). We recommend using the mat for a while to see if you would like the controller (or you can purchase it with your mat).
It is most common to leave your FeelsWarm heating mat on at all times but you may choose to utilize a controller for the mat. Click here to see a survey of the controller usage by FeelsWarm customers.
