Dual Protections: The aquarium temperature controller is equipped with 2 relays to ensure that the plugged heater can be turned off when detected overheating, protecting your fish tank well
2 probes get more reliable: place them in a fish tank but at a distance, the controller will alarm when the temperature difference is over 3 degrees Celsius (5 degrees Fahrenheit), and the App will push a notification to your cell phone at the same time
Customize Heating Time: You can determine the heating time from 1 to 72 hours; The controller will alarm you when the time out but the temperature still could not reach the expected level
Temperature Setting: 20.0 to 35.0 degrees Celsius or 68.0 to 95.0 degrees Fahrenheit; and the detectable temperature range is minus 40 to 100 degrees Celsius or minus 40 to 212 degrees Fahrenheit
Plug and Play: The 1100 W aquarium temperature controller is compatible with most kinds of heaters, you don’t need to assemble the product yourself, it is plug and play
APP Notification: Pair the aquarium temperature controller with your phone via 2.4 GHz Wi-Fi, and the device will alarm if there is any exception, and the INKBIRD app will push notifications to remind you
