The Tado Smart Radiator Thermostat X Starter Kit 3-Pack allows for precise temperature control in individual rooms, even without a central heating boiler. It connects to your smartphone app for convenient management and includes energy-saving features such as temperature scheduling and automatic shut-off when windows are open.
