Which radiator valves can the FRITZ!DECT radiator control be used with?

FRITZ!DECT 301 can be used with all common radiator valves. The radiator control can be mounted directly without an adapter on most standard M30 x 1.5 mm valves, and you can use the adapter included with delivery to mount it on common Danfoss RA valves. You can purchase suitable adapters for less common types of heating valves through online vendors or electronics retailers.
