When the detected water temperature is too low, the relay indicator light is on, indicating that the analog heater is heating. When the detected water temperature is too high, the other relay indicator light is on, indicating that it starts to cool down until the temperature fluctuates within a certain range, so that the temperature of the fish tank can be suitable for the survival of the raised fish.German
Wenn die erkannte Wassertemperatur zu niedrig ist, leuchtet die Relais-Kontrollleuchte, die anzeigt, dass die analoge Heizung erwärmt wird. Wenn die erkannte Wassertemperatur zu hoch ist, leuchtet die andere Relais-Anzeigeleuchte, die anzeigt, dass es beginnt abzukühlen, bis die Temperatur innerhalb eines bestimmten Bereichs schwankt, so dass die Temperatur des Fischtanks für das Überleben der aufgezogenen Fische geeignet sein kann.
