Aquarium Heater for 15-30 Gallons with Adjustable Temperature Controller (25W)

Automatic temperature control with 1°F accuracy: The AUOMII aquarium heater utilizes advanced Intelligent Frequency Conversion Technology to maintain water temperature with up to 1°F precision. To set the temperature, simply press the "SET" button to adjust in 1°F increments until the desired level is reached. The setting will activate automatically after 3 seconds of no further input.

Heating and cooling control: The heater will automatically start working if the water temperature drops 1°F below the set point, indicated by a red LED light. Once the target temperature is reached, the heater will automatically shut off, with a green LED signaling no heating is required.

Overheating and dry protection: The heater is equipped with built-in water level and temperature sensors to prevent overheating and dry operation. If the heater is out of the water or the water level is too low, it will stop heating and display "E1" error. Similarly, if the water temperature exceeds 95°F, the heater will shut off and show "H1" error. Normal operation will resume once the issues are resolved.

Error codes and indicators: The heater has a 3-color LED indicator system. Red indicates heating, green indicates no heating, and yellow signals a fault. The error codes "E1" (out of water), "H1" (overheating), and "H2" (dry running) provide clear diagnostic information.

Intelligent memory function: The heater automatically remembers the last temperature setting. If power is lost and restored, it will revert to the previously set temperature, protecting your aquatic life.

Compact and versatile design: The small 2.9 x 2.7 x 1.2 inch size makes this heater ideal for mini aquariums. Three strong suction cups enable easy installation, and the discreet design allows for hidden placement within the tank.

External temperature control: While the heater itself is not waterproof, it features an external temperature controller for convenient adjustments. This allows you to set and monitor the water temperature with ease.

Built-in thermometer: Dual temperature sensors provide accurate real-time water temperature readings, displayed on the LED display for at-a-glance monitoring.

Diverse applications: This AUOMII heater is suitable for freshwater, saltwater, and marine aquariums, as well as other applications like turtle tanks, pet fountains, and hydroponic systems.

Available in a range of wattages: 10W, 20W, 30W, 25W, 50W, 100W, and 150W models are offered to accommodate aquarium sizes up to 30 gallons.

With its precise temperature control, safety features, and versatile design, the AUOMII aquarium heater provides a reliable solution for maintaining optimal conditions for your aquatic inhabitants.
