The thermostat is a wirelessly communicating radiator controller with a modern ergonomic design, featuring functions for enhanced comfort, temperature regulation, and energy savings. The radiator controller communicates at a frequency of 868 MHz and can be easily integrated into the evohome heating system. The large illuminated display and adjustable display position ensure better readability. The included display holder keeps the display in the desired position. The display turns on as soon as the button is pressed or the dial is turned. Manual room temperature adjustments are possible at any time. Thanks to the open-window detection, the heating valve closes when the room is ventilated. With quick and easy installation, there is no need to drain the heating water anymore.
