This creation is a kind of related temperature controller for fishbowl of what,It is by an electric power supply unit,One voltage-adjusting unit,One control unit,One output unit,One setup unit,One temperature detecting unit and a display unit are formed,The set water temperature of the water temperature that wherein the control unit system is detected according to the temperature detecting unit and the setup unit carries out operation and compares,And a corresponding control signal is exported with conversion system,And work as water temperature close to set water temperature and setting in difference range,The control unit then changes gradually successively decreases the calculating of its output power according to the time cycle of setting,And using this calculated result as the output of control signal,The output power of the output unit is controlled by the control signal,For the heating actuation of a heating device,Using the composition of above-mentioned each unit,The power consumption of heater for fish bowl can be effectively reduced in spy,And then reach energy saving person.本創作係有關於一種魚缸溫度控制器，其係由一電力供應單元、一電壓調整單元、一控制單元、一輸出單元、一設定單元、一溫度偵測單元及一顯示單元所組成，其中該控制單元係根據該溫度偵測單元所偵測的水溫與該設定單元的設定水溫進行運算比對，並以變頻方式輸出一對應的控制訊號，而當水溫接近設定水溫且在設定差值範圍內，該控制單元則改依設定的時間週期逐次遞減其輸出功率的計算，並以此計算結果作為控制訊號的輸出，藉由該控制訊號控制該輸出單元的輸出功率，以供一加熱裝置的加熱作動，利用上述各單元之組成，特能有效降低魚缸加熱裝置的耗電量，進而達到節能省電者。
