A kind of temperature regulating device of Shui nationality heater,System put what one have the Cultivation container of liquid it is outer,And be electrically connected with the heater inside the setting what Cultivation container,And temperature regulating device system include a microprocessor,One temperature setting key,One temperature-sensitive sticker,One first display,One second display,One power input,One power supply unit,One first control switch,One second control switch and a power output end,Wherein the microprocessor can set a built-in temperature power-down value,And the temperature setting key can to press with carry out a set temperature power-down value adjustment,It with second control switch is to connect by what first control switch,And when the temperature that the temperature-sensitive sticker the measures high what set temperature power-down value,The microprocessor then will disconnect first control switch,If the temperature that the temperature-sensitive sticker measures continues to increase,It is failed that the microprocessor then judges first control switch,Therefore second control switch can be disconnected by the microprocessor again,To avoid power supply continues through first control switch and second control switch and supply power to the heater,The Cultivation container is set to also continue heating at high operating temperatures,Such control device will avoid the biology cultivated in the what Cultivation container dead due to high temperature.一種水族加熱器之控溫裝置，係置放於一具有液體之養殖容器外、並與一設置於該養殖容器內部的加熱器進行電性連接，而控溫裝置係包含一微處理器、一溫度設定按鍵、一溫度感測器、一第一顯示器、一第二顯示器、一電源輸入端、一電源供應器、一第一控制開關、一第二控制開關及一電源輸出端，其中該微處理器能夠設定一內建溫度斷電值，且該溫度設定按鍵能夠用以按壓以進行一設定溫度斷電值的調整，由於該第一控制開關與該第二控制開關是進行串聯，而當該溫度感測器所量測之溫度高於該設定溫度斷電值時，該微處理器則會斷開該第一控制開關、若該溫度感測器所量測之溫度繼續升高時，該微處理器則會判斷該第一控制開關已故障，因此會再由該微處理器斷開該第二控制開關，以避免電源持續通過該第一控制開關與該第二控制開關而供應電力至該加熱器、使該養殖容器在高溫狀態下還繼續加熱，如此控制裝置將能夠避免於該養殖容器內所養殖的生物因高溫而死亡。
