RF Wireless Key allows easy control and your mobiles to work with Worcester Bosch Boilers
It acts like a sim cart pushing in the boiler special connecter so easy and set up your wifi or broadband and go Then you can control your boiler from your smartphone or from easy control.
If you don't want to run a wire from your EasyControl to your boiler, this does the job wirelessly. Easy to install and pair, though it doesn't stay firmly in its socket and can be knocked loose when the boiler bottom cover is off. Not a problem most of the time.
