The Fluval E Series Advanced Electronic Aquarium Heater features a LCD display that will show your temperature in either the Celsius or Fahrenheit scale. Of course, this can be somewhat confusing if you prefer to use one temperature display format over the other. Thankfully, you will be able to switch between these two scales with this device.
To see how you can change which format is displayed on the LCD screen of the Fluval E Series, you can take a look at this tutorial from Aquarium Blueprints.
Before we begin, it should be noted that this guide covers all four versions of the E Series, which includes the following products:
- Fluval E50 Advanced Electronic Aquarium Heater
- Fluval E100 Advanced Electronic Aquarium Heater
- Fluval E200 Advanced Electronic Aquarium Heater
- Fluval E300 Advanced Electronic Aquarium Heater
1. To start off, make sure you properly install the heater in your fish tank if you haven’t done so already.
For the uninformed, the E Series needs to be placed close to a high water flow area, which is usually the output nozzle of a filter or water pump.
You should also make sure that the water line of your tank is above the minimal water line of the heater so that the device will function normally and display an accurate water temperature reading.
If you are using the E Series for the first time, or took it out of the tank, then you need to let the heater sit in the tank water for at least 20 minutes before you plug it into a power source.
Once you plug the heater into the power source, give the device a few minutes to self-calibrate.
2. You should see the temperature display on the LCD screen of your E50, E100, E200 or E300.
If you bought the heater from a region that uses 50 Hz, such as Europe, then the temperature will display in the Celsius scale by default.
If the heater was bought from a 60 Hz region, such as the United States, then you will see the temperature displayed in the Fahrenheit scale in the factory settings.
3. In order to switch from the Celsius format to Fahrenheit format or from the Fahrenheit format to the Celsius format, you need to hold the set lever located at the top of the heater to all the way the minus side for at least 5 seconds. For the uninformed, this is the same lever used to adjust the desired temperature of the heater.
If you are looking at your E Series from the front, then you need to hold the lever all the way to the left side.
4. After holding the set lever to the minus side for at least 5 seconds, you can let go.
5. A few seconds later, the scale should switch to the alternate format.
So, if the LCD was displaying the Celsius temperature before, then it should now the Fahrenheit temperature.
If the display was previously showing the Fahrenheit scale, then it should now be showing the Celsius scale.
You can perform the same action again if you want to switch back to the original temperature display format of your E Series.
