Over heating heaters is a hobbyist nightmare.  To protect your aquarium investment and live stock, this heater controller is a must.  The digital controller maintains your heater within a safe temperature providing a healhty and stable temperature for your aquarium.  Automatic shut off over heat protection will alert it's internal sound alarm and cease the heating process.  A temperature probe is included to ensure a more accurate aquarium temperature reading.  The three prong power receptacle works well with other compatible heating elements equal to or less than 300 Watts.  Add a controller for double heating protection! If power is interrupted a memory chip is incorporated to resume users preset temperature once power resumes. *Do not use with defective heating tubes.  Defective heater tubes may be drawing excess watts and in turn make the MAX 300 controller fail.
