4 BOOST SETTINGS FROM 15 MINUTES TO 2 HOURS: Choose ¼, ½, 1 or 2 hours of boost with a single button. Just press repeatedly to pick your time, and the unit switches off automatically when the boost ends. It's ideal for immersion heaters, towel rails, panel heaters and other fixed appliances. SEE TIME REMAINING AT A GLANCE: LED lights show your selected boost and go out one by one as time counts down, giving you a handy guide to how long is left. The next LED flashes when there are less than 2 minutes remaining on that stage. QUICK TO CHANGE OR CANCEL: Changed your mind? Adjust the boost within the first 15 seconds, or cancel at any time after that with a single press. There are no clocks or programmes to set, so it's simple for the whole household to use. HANDLES LOADS UP TO 13A (3kW): Rated for 13A resistive loads, 1000W filament or halogen lighting, 500W fluorescent, 100W low energy and 80W LED lighting.
