Please check your mat connector for the number of prongs. Please add a note to your order including what model of the mat you need a controller for.

Each controller is built to accommodate 110V as well as 220V, 50-60Hz. It is the construction of the mat itself that works for either 110V or 220V. When you order a 110V or a 220V unit, we make sure that you receive a specific mat that was made to accommodate the desired voltage. It is perfectly safe to use your mat with the controller provided in the package.
