When the water temp in the tank differs significantly from the set temp, the heater will quickly bring the water up to temp. When the water temp in the aquarium is close to the set temp, the heater will work at a lower power to heat up gently and consistently. This saves electricity and avoids sudden temp fluctuations that can cause stress to aquatic life. Please ensure the heater is fully submerged vertically in the aquarium water, or horizontally in the terrarium water. 【Dual-Sensing Temperature Probe Design】This design enables more precise temperature control: Temperature control range 59-93°F/15-34°C, accuracy ±0.3°F/0.2°C. The design is basedon independent temperature collection and mutual supervision mechanism. lf any probe fails, the aquarium heater will immedi-atelyflash an "E2"alarm. At the same time, the circuit is disconnected toensure that it will not over-temperature, That can effectively prevents the "cooking the fish" phenomenon that occurs when temperature sensors malfunction. 【Premium Safety & Durability】The durable material of the turtle tank heater ensures safe operation. The outer shell covering the whole body of the heater is made of heat-resistant ABS material that it won’t deform and melt under high temperature. The heating rod is made of nickel-chromium heating wire to faster heating rate, and non-corrosive thickened quartz glass. 【Intelligent power cut-off, Comprehensive Protection】This heater has a unique intelligent water and temperature sensor system, providing comprehensive protection: ①Over-temperature alarm: When water temperature exceeds the targe temperature, it shows "HH" and automatically stops heating. ②Off-water alarm: When the water level is lower than aquarium heater's water level, it flashes "E1" and automatically stops heating. ③ When any one of the temperature sensors malfunctions, it shows "E2"and automatically stops heating. 【Cautions】1.Please ensure the heater is 100% submerged into the water before plug in the power. 2. Please unplug the power and cool down the heater for 10-20 minutes before taking it out to clean the fish tanks or change the water. 3. Aquarium heaters should be placed in flowing water, otherwise temperature stratification will occur. 【Guaranteed Customer Service】HarmonyHome fish tank heater is made with great safety and durability for use.
