A timer allows for controlling of your heated bathroom towel rails to help control the running costs by not having the rail on all the time.The EB11 Boost Switch is a simple manual count down timer. Each time you want to use the rail you simply press the boost button for the number of time increments required. One press will do 15 minutes, two presses will do 30 minutes and so on through the remaining increments of 1, 2 and 4 hours. The blue light will shine to indicate the time the rail will be on for and each increment will flash before it finishes. Once the countdown is complete the rail will switch off, ready for use again next time.Extremely simple to use, the EB11 is a great option in applications where you don't want to program the rail but also don't want it left on such as in a visitors bathroom. As the EB11 doesn't fit onto the wall bracket as standard a separate back box is supplied with the unit.
