Installation: what UK buyers need to know

Fits radiators with a thermostatic valve body: M30 × 1.5 thread, with 6 adapters that tado° says fit 95% of radiator valves. Works on wet radiator systems; with a heat pump, room control depends on how the system is set up. If you are not confident with the wiring, use a qualified installer.
