The package includes a 200W/300W/500W Heating Element, an External Heating Controller, 2 Suction Cups, and a User Manual.

The heater features a red light to indicate heating and a green light for constant temperature and heating stop. It adopts a high-precision imported IC chip and a PID optimization system for monitoring. The micro-software control gradually increases the working current from 0 to the rated current, significantly improving the service life of the heating element and ensuring accuracy and reliability.

The digital display shows the current real-time water temperature. The heater is equipped with a built-in temperature detector and water protector.

The heater has several safety features: 1. Out of Water Protection: When the heating rod leaves the water surface, the green indicator and the display will flash, and a warning signal (E1) will be issued, forcing the circuit to shut down. 2. Over-Temperature Protection: When the water temperature exceeds 95°F (35°C), the green light and the display will flash, a warning signal will be issued, the display will show (HH), and the circuit will be forced to shut down until the temperature returns to 94°F (34°C) and automatically resumes normal operation. 3. Heater Malfunction: If the probe is short-circuited, the display will show (E2), and the indicator lights will flash simultaneously, giving out a warning signal and forcibly shutting down the circuit.

It is crucial to follow the user manual strictly. The entire body of the heater element must be fully submerged in water and placed in the path of water flow, not buried. Unplug the heater and wait 15 minutes before changing the water or removing the heater. The plug and controller should always be kept dry and never be placed in water.

The heater is designed to be explosion-proof and anti-scalding, ensuring the safety of your fish. It features energy-saving technology, providing fast heating to create a suitable living environment for your fish, even in the cold winter. The precise temperature control and water shortage protection further enhance the reliability and safety of the heater.
