Characteristics

● Built-in double controller, double sensor, water and power, single display, button heater.

● The world's first and multinational patents: the independent two-group controller contains two sets of control lines and
independent temperature sensors.

 A. Main control line: temperature setting, temperature display, temperature control and other functions are operated by the main control line.

 B. Over-temperature protection control line: when the water temperature exceeds 33℃, remove the heating rod power
supply.

● Adopt imported aquarium special wafer, microcomputer temperature control, full electron digital circuit, high stability,
aquarium special heater, set temperature range: 20-32℃, scale: 1℃, temperature accuracy: ± 1℃ / 2 ℉; LED temperature
display, temperature easy to read, single key setting simple operation.

● Use the key mode of operation, is more convenient to use.

● The world's first double independent control line and 6 major protection:
1. When the water temperature is 3℃ above the set value, force the heating to stop and the red light stops. The water
temperature display flashes a warning.

2. When the water temperature is lower than 3℃ above the set value, the water temperature display flashes warning and the
red light is on, it will still warm.

3. When the sensor is open, the water temperature display displays Lo and forces to stop heating. When the sensor short
circuit, the water temperature display shows HI and forcibly stop heating.

4. Water protection: when the water level is too low, the blue light will always light on and the display will display 88 flashing
warning to stop heating. Water level recovery, automatic return.

5. Overtemperature protection: when the water temperature exceeds 33℃, the display displays HI, the red light goes out, and
forcibly stop the heating. When the water temperature drops, it returns automatically.

6. Over temperature protection control line: when the water temperature exceeds 33℃, the over temperature protection
control line moves, the yellow light is on, the red light goes out, and the heating is stopped. When the water temperature
drops, it returns automatically.

Installation instructions

1. Check whether the voltage of the power supply is consistent with the product label.

2. Install the heating rod and the suction cup clip, select the position with strong water mobility in the tank, put the heating
rod into the water, fix the suction cup on the heating rod on the cylinder wall, and the heating rod is put into the water.

Warning: Power cord plug shall not be placed in the water.

3. Please be sure to completely immerse the heating rod in water to avoid the water temperature sensor can not sense the
water temperature and correctly control the water temperature, resulting in high water temperature, do not bury the heating
tube in the bottom sand or poor circulation position.

4. Insert the power plug into the power socket, press the button, increase the set value by 1 until the desired temperature
number is on, stop press the button, then the set temperature number will blink, and then stop flashing.

6. Red indicator light represents heating. When the red indicator light is on, the heating tube is heating; when the heating
indicator light goes off, the heating tube stops heating, but note that the heating tube itself still has residual temperature.

7. The yellow indicator represents too high water temperature. When the over temperature indicator is on, and the over
temperature protection control action and the removal heating action, please unplug the power supply and stop using.

8. The blue indicator represents the water warning, and the display is 88 and flashing, please add water to the fish tank or
heating rod must be immersed in water.(The water separation sensor position is above the heating rod, please do not add
suction cups or debris such as algae close to the heater position from the water separation induction area)

Matters need attention
1. The heater must be put directly and completely immersed in the water, and fixed in the smooth

position of the water flow,

otherwise the temperature sensing will be inaccurate.

2. Do not bury the heater in the bottom sand for use, which results in poor heat dissipation of the heater, shortens the service
life of the heater, and cannot be heated to the accurate water temperature. The heater should be placed above the
bottom sand, and the water flow should be used smoothly. The suction cup is located away from the water protection
induction zone.

3. The power supply of the heater should be used alone, and attention must be paid to whether the power socket is good and not loose.

4. This heater is a segmented heating method, and the heating temperature curve is stepped, to avoid the heating
temperature rising too fast, resulting in biological discomfort in the fish tank.

5. The plug part shall not be soaked in water, nor shall it be splashed, touched or placed in a wet environment above the sink.

7. This device is a heating equipment, do not contact the heating surface of the heating tube with the body or flammable
materials in the heating. If the heater needs to leave the aquarium, change the water or before the water, please be sure to pull out the power plug, and wait for more than 15 minutes to take out the water, to ensure the safety of electricity and avoid danger.

Warning: Unplug or turn off the power supply before the appliance is moved out of the tank.

8. Limited to indoor glass aquarium box. This heater is used for ornamental fish, do not do other chemical liquid heating. And
for indoor special, do not use outdoors, heating pipe body can not be knocked, collision.

9. The appliance is not intended to be used by users (including children) with insufficient physical perception, intelligence,
experience or knowledge, except under the supervision or guidance of persons responsible for their safety. Children should be monitored to ensure that they do not play with electrical appliances.

10. Before maintenance, remove all electrical appliances of the aquarium or turn off the switch.

11. In order to ensure safety, please pay more attention to the change of water temperature in the first two days. If the
aquarium raises red dragon fish ,breams and stingray, it is suggested that the thermometer should be used with a temperature controller to double guarantee to ensure the safety of use.

Warning: Except for the product warranty, it is not responsible for it.

12. When the temperature too high (yellow light) indicator is on or the display shows HI, the temperature is too high, please
immediately unplug the power and stop using.

13. If the heating bar is abnormal, please stop using it immediately and do not remove it by yourself. It must be repaired or
replaced by the manufacturer or its dealers to avoid danger.

14. The power cord of this heater cannot be replaced by itself. When the power cord is damaged, the heater must be stopped and used and discarded immediately, or repaired and replaced by the manufacturer or its distributor to avoid danger.

15. The maximum depth of this heating bar can reach 1 meter.

16. When selecting the heating bar, it must be used with the appropriate aquarium water, especially the water is less than 5
liters. Never use the heating bar with high wattage (power), which is easy to cause the over temperature phenomenon of the
aquarium.

17. Choose heating rods of different power, which should be matched with fish tanks of different sizes, please refer to the
product specifications.
