Finally a solution

Easy to operate and set up and fit - after 18 years with an older model which was permanently set to "on" we have wasted hundred of pounds in unnecessary energy heating a boiler because the settings were not working.At last a simple solution - should have sought this out years ago!Read full review

Easy replacement for the existing model. Straight swap onto current wall plate, no rewiring needed. Stylish design, easy to operate, a good product.
