This setting can also be changed so that the thermostat searches and recommends the best tariffs for your review

    The thermostat can connect with your smartphone, tablet or computer to allow you to control your heating online. By downloading the MyHeating™ app and logging into your account you will be able to control your heating, evaluate your energy usage and optimise your temperature settings on the go.

    Early start technology ensures that your home is at the right temperature at the right time. The 4iE does not require programming, it works with your smartphone to ensure the temperature at home is always the temperature you want, just as you arrive and using more efficient temperatures whilst you’re away from home. The MyHeating app is also simple and easy to use if you do prefer to use a conventional programme or want to make a quick change to your heating settings.

    You can set your 4iE to your schedule, which will make the thermostat program itself and automatically suggest ways for you to save energy, reducing your bills.
