Safe to use with a protection mechanism
This hygger aquarium heater maintains the proper temperature for your fish safely, auto shuts off when over-heats, and resets when it cools down. The heater will shut off when removed from the water and resume functioning upon return.
Over-heat Protection
This aquarium heater has over-heat protection to help maintain the proper temperature for your aquarium safely, it will auto-shut off when it overheats, and reset when it cools down. The hygger 969 heaters will shut off when removed from the water, and resume functioning upon return.
Energy-saving
The 500-watt heater heats your aquarium at full speed once it is plugged in. You can see Max on the screen. When it reaches the proper temp, it stops. Once the water temp drops 1 degree or so, the heater heats up again at low energy to keep the proper temp. You can see ECO on the temperature controller screen. In this way, the heater saves energy greatly.
Easy to set temperature
You can set the tank temperature without getting your hands wet. Just keep pushing the button on the controller. It will cycle through all the set temperatures. You can precisely adjust the temperature from 68 to 93 °F (20 °C ~ 34 °C), and the electronic thermostat is accurate to +/- 2 degrees Fahrenheit.
Shatterproof & Corrosion resistant
Corrosion-resistant and shatterproof titanium tubes construct heat fast, nearly unbreakable for freshwater aquariums only. An ABS plastic protective sleeve prevents fish from being scalded.
Directions for Use
How to Set Temperature?
Step 1: Place the aquarium heater rod underwater and fix it on the wall.
Step 2: Plug it in, and you can see an LED digital number flashing 3 times that shows the current water temperature with red indicator lights on.
Step 3: Press the “Set” button to set your desired temperature, which will blink for 3 seconds.
Step 4: Start to heat the water. Once it reaches the desired temperature, the indicator light will switch to green.
Useful Tips
1. Make sure that the heater doesn’t touch sand or gravel on the tank bottom.
2. To avoid the device overheating and ensure its better performance, it’s better to put it close to the tank filter.
3. Don’t plug in the heater if it’s not completely drowned in the water.
4. Unplug the heater first before the water change.
I been using this heater for over a year and last week when I checked it had a “Er” error code. This means that the heater is out of the water. Well it’s not and it’s well below the minimum. After contacting service and sending a small video clip with a picture of the problem they are sending me a brand new heater.
Thank You Hygger
By the way all my high wattage heaters are Hygger
Great Heater ,used for 9 months en it broke down,mailed Hyger 2 days later new delivered ,great customer service (thanks guys) now running for 10 months and no problem ,great heater nice to use controller
I love this heater. The units works great keep 220 gallons at a steady temperature, I like the design of it as well , I got tired of seeing the typical glass heaters in the tank. Also a very long power cord meant it doesn’t strain the power cord when installing in a tall tank. The digital controls are also excellent way to change the temperature if needed.
