Key Features Rapid Double Relay Heater The HG275 features a double heating rod, making it a more powerful and longer-lasting heater for faster water heating and safer for both saltwater and freshwater fish tanks. LED Digital Controller HG275 double relay heater comes with an LED controller, which shows the current water temperature and the preset temperature in °F and °C. It shows Low/Hi temperature and Auto shut off warning sign in real time for easy setting and operation in a temperature range from 59°F(15°C) to 93°F(34°C) with set temperature ±1°F(±1°C) accurate. When the temperature reaches 94°F(35°C), there is an HH warning signal. More Durable Heating Rod The heating rod is made of explosion-proof quartz glass material and a high-temperature resistant nickel-chromium heating wire with silicon carbide heat conduction, making the double heater more durable and having a long service life. Precise Temperature Control When the water temperature reaches the set temperature, the HG275 heater shows power zero. When the current water temperature is 1°F(1°C) lower than the set temperature, the indicator light turns red and starts heating automatically. Auto Power Off & Warning When the heating rod is exposed to air, the heater will auto shut off and emit a warning signal. It will start working automatically when the heating rod is completely immersed in the water. Memory Function If there is a power outage, the heater will keep the previous temperature settings after the power is back. Usage Tips Install the sucking cup onto the heater rod, and turn it 90° to lock the cups. Connect the heater to the socket to use it directly. Only use the heater in freshwater or saltwater; do not use it in other liquids. To avoid possible electric shock, do not immerse the switch in water. If the switch falls into the water or becomes wet, do not touch it until you have unplugged it.
