Abstract

Die Erfindung betrifft eine Schutzvorrichtung für einen Warmwasserspeicher mit einer wärmebedarfsabhängig gesteuerten Speicherheizung (16), mit einer in den Speicherraum ragenden Meßanode (40), die durch Fremdstrom gespeist und an einer Auswerteelektronik (44, 50) angeschlossen ist. Es wird vorgeschlagen, daß die vorzugsweise über das Netzteil (46) im Heizgerät (16) versorgte Auswerteelektronik (44, 50) der Fremdstromanode mit der Steuereinrichtung (32, 54) der Speicherheizung (16) verbunden ist und bei Fehlen des Anodenstroms ein die Inbetriebnahme der Speicherheizung (16) zwangsläufig verhinderndes Sperrsignal an die Steuereinrichtung übermittelt.The invention relates to a protective device for Hot water tank with a heat demand controlled storage heater (16), with one in the Storage space protruding measuring anode (40) by external current powered and on evaluation electronics (44, 50) connected. It is suggested that the preferably via the power supply unit (46) in the heater (16) supplied evaluation electronics (44, 50) of the external current anode with the control device (32, 54) of the storage heater (16) is connected and commissioning in the absence of anode current the storage heater (16) inevitably preventing blocking signal to the control device transmitted.

Dadurch wird verhindert, daß ein Warmwasserspeicher in Betrieb genommen und beschädigt werden kann, wenn eine ausreichende Schutzwirkung nicht gegeben ist oder wenn die zugeführte Heizenergie vom Speicherwasser nicht aufgenommen werden kann.
