Feature: 1. Stable: The fish tank heating rod adopts thickened explosion proof quartz tube, which is stable in heat resistance, and the nickel chromium heating wire quickly and stably conducts heat. 2. Speed Heating Mode: Instant high power heating at the beginning of work, until it is close to the set temperature, low power constant temperature, energy saving and power saving. 3. Intelligent Temperature Control Chip: 20℃~34℃ cycle temperature control is convenient and quick. High definition LED control display, real time monitoring of fish tank status. 4. Low Temperature Alarm: The fish tank heating rod is easy to install and disassemble, the water temperature is lower than 20 ℃, the fish tank heating rod low temperature alarm flashes LL. 5. Over Temperature Alarm: If the water temperature is higher than 34℃, the fish tank heating rod will flash HH alarm. Sensor failure displays EE and stops working. Specification: Item Type: Fish Tank Heating Rod Material: ABS+Quartz Glass Tube Size: Approx. 29 x 5.7 x 4cm/11.4 x 2.2 x 1.6in Recommended Fish Tank Size: Below 180cm/70.9in European Standard: 110-240V Applicable Water Volume: Below 700L. Package List: 1 x Heating Rod2 x Suction Cup1 x Instruction Manual Note: Troubleshooting methods:1. Temperature difference: it takes 10‑30 minutes for the probe to adapt to the current water temperature according to the user's different environment (water flow, placement position, etc.). What is detected is the temperature around the rod body, which may deviate from the overall fish tank water temperature, resulting in HH and high temperature alarmSolution: Put in the water circulation position, let the heat with the water circulation, to achieve the same effect of water temperature2, can not reach the specified temperature: the water volume and water area in the cylinder, indoor temperature difference, water heat emission, can affect the heating water temperatureSolution: You can change the position of the rod body and place it in the position of water circulation to evenly dissipate heat. You can also refer to the applicable water amount and size of the fish tank3, leakage: the environment is not the same, the pen test may show that there is electricity, only about 20V, and aluminum shell mobile phone charging, using the hand induction as if there is electricity is the same principle, is the induction current, not leakage4, sucker drop: sucker is a strong silica gel, part of the customer stuck to the glass will fallSolution: Clean the glass surface and the bottom of the suction cup, and reinstall the suction cup against the glass5, the screen does not display: check the power socket, the use of the environment is standard voltage, circuit board is composed of more than one hundred kinds of electronic original devices, such as the use of the environment is no problem, please stop using6, the screen is displayed, but not heated:Solution: Unplug the power supply and reset the temperature. If the red light is on, it means the heating element is damaged. Please stop using it
