If you purchase exchange electricity, the app that controls the smart thermostat will monitor the rates and choose the most affordable time for heating. **Smaller Carbon Footprint** Themo Smart Thermostat will work to protect the environment on your behalf. It aims to reserve heat energy in the floors when the availability of renewable energy in the grid is at its highest. Comfort **Flexible Heating Schedules** Themo Smart Thermostat will take your daily routine into account. You can create a personal heating schedule based on the times you are at home and away. **Real-time Information on the Price of Electricity** Even though Themo Smart Thermostat was designed for optimizing heating costs, you can also utilize the data it provides with other electrical devices in your home. The LED light on the thermostat changes color to show you in real time whether the price of exchange electricity is high or low. This will let you know the most affordable time to use appliances that consume substantial amounts of electricity.  Reliability **All Information Is Kept Secure and Protected** SSL encryption ensures that all your data remains secure and protected. This means that you will not have to worry about unauthorized access to your data. **Conforms to EU Regulations ** Themo Smart Thermostat bears the CE marking. This means that our thermostat meets all EU requirements. ## Should I purchase Themo Smart Thermostats or a Themo DIN electric heating controller? We recommend installing a Themo Smart Thermostat in each room with underfloor heating that you want to control. If your home only has underfloor heating in the bathroom, a single Themo Smart Thermostat is enough. If you choose Themo DIN, which is mounted onto the switchboard of the property, you will only need a single device. Themo DIN allows you to control underfloor heating or regulate the operation of a storage water heater or heat pump. You can of course also control underfloor heating in a room-specific manner with Themo Smart Thermostats and your storage water heater with a Themo DIN. ![themo-themoBlack_800x350_1](https://www.themo.io/hs-fs/hubfs/themo-themoBlack_800x350_1.jpg?width=800&name=themo-themoBlack_800x350_1.jpg) ### Getting a Themo smart thermostat or Themo DIN for your home Purchase a Themo Smart Thermostat for each room with underfloor or ceiling heating.  You can also purchase a Themo DIN controller that is mounted onto the switchboard and allows you to optimize the electricity consumption of a storage water heater, heat pump, or electric underfloor heating.
