All heat mats are compatible and interchangeable with all thermostats, as long as the total heat mat wattage does not exceed the thermostat's rating. For example, the Redi-Heat Four Outlet Thermostat is rated for up to 2,400 watts, so it can handle any combination of heat mats totaling 2,400 watts or less.
