The Fluval “E” series heaters feature an LCD temperature
display that indicates water temperature (Celcius or Fahrenheit)
in real time, through a dual microprocessor.
The temperature readout will change colour if the aquarium water
varies by +/- 1 oC (2 oF) or more from the pre-set temperature.
The screen will flash to indicate potential risk should the aquarium water temperature rise or fall beyond 3oC (5.5 oF).
