| Zusammenfassung: | The device (7) has a heat pump (8) with lifting magnets (4) and a flushing valve (9) connectable with the magnets. A positive temperature coefficient (PTC)-resistor (5) with a non-linear resistance curve is connected in series with the lifting magnets. The resistor is heated by a current flow and is highly resistive if a preset marginal temperature is exceeded such that the temperature in the resistor reaches the marginal temperature before exceeding a permissible on-time duration of the magnets. The lifting magnets are connected with an electronic circuit (6) for controlling the magnets. |
