Getting comfort from your patio heater is impossible without a switch. How are you supposed to adjust the heat or turn it on/off when you want? And if you have 2 or more heaters installed, easily adjusting the heat is all the more important. Get an Eurofase Wall Plate Dual/Single Duplex Switch and take control over both elements of your heater. You'll be able to precisely optimize the heat that your heater emits and save energy while keeping maximum comfort. A dual duplex switch offers the advantage of controlling two heaters, while a single duplex switch is limited to adjusting only one heater. Both switches can independently control each element, allowing you to set it at high or low. To manage multiple heaters simultaneously, creating zones with a control box is required. Use this reliable switch for effortless heat adjustments. Grab yours now and enjoy free shipping! What's Included:Duplex Switch and User's Manual
