The Warmup 4iE Smart Wi-Fi touchscreen thermostat offers features including SmartGeo and EasySwitch. It can be controlled from a tablet, computer or with the Warmup MyHeating app for iOS and Android. The 4iE doesn't require programming, and works to ensure your home is always at the temperature you want when you arrive. The MyHeating app is simple and easy to use. The 4iE learns how you use your heating, and how your home responds to changes in temperature to calculate more efficient settings. EasySwitch also works to find the best energy deals and tariffs, making it easy to switch. The large colour touchscreen can be customised with different themes and photos. It also offers a 7-day weather forecast and traffic alerts. It's suitable for use with both central and underfloor heating systems.
