The 'Reset Device' command in ETS performs a software restart of a KNX device without erasing its individual address or its application configuration.
True
Reset Device = warm restart: the device loses its runtime state (RAM), reinitialises its timers, Cyclic Send and counters, but preserves its individual address, application program, ETS parameters, and Group Address to Group Object bindings. It is useful to force the re-emission of initial values (cyclic send after a crash), to test a specific power-up behaviour, or to unstick a device frozen in an inconsistent state without having to reload the configuration. Not to be confused with Unload All (full decommissioning) or with simply switching off mains power.
Use Reset Device before troubleshooting a misbehaving actuator — if the symptom disappears after a reset, the fault is a runtime glitch rather than a configuration mistake, and ETS download will not fix it.
