Controller Details & Compatability


Multi-channel Lighting Control


  • Control up to 32 independent channels of dimmable and non-dimmable lamps
  • Freely programmable
  • True calendar moon phase: Simulates the lunar rhythm in harmony with nature and promotes species-typical behavior.
  • Sunrise and sunset simulation
  • Seasonal lighting: ProfiLux Aquarium Controllers (beginning with version 3) are capable of simulating the seasonal cycle of sunshine duration and sun intensity.
  • Thunderstorm simulation: Simulate lighting-effects in conjunction with dimmable GHL lights. Programmable storm parameters allow you to change the frequency, intensity, and duration of a thunderstorm.
  • Rainy day simulation
  • Cloud simulation: Programmable random generators allow you to define the beginning, intensity, duration, and speed of a cloud – soeach time new clouds are created.
  • Temperature-dependent light reduction: for short-term temperature peaks on hot summer days.
  • Tropical twilight
  • Gentle lighting transition from summer-time to winter-time laid out across several days.
  • PWM interface for LEDs


Lab Grade Measurement and Controllability


  • Water temperature monitoring/control: Program heaters, ground heaters, and cooling devices for maintaining temperature; Nightly cooling can also be programmed. Intelligent summer-circuit for optional ground heating.
  • pH monitoring/control: Program up and down pH regulation via CO2-addition (pH-decrease) or via Alkalisation (pH-increase); Nightly decrease can also be programmed.
  • Redox monitoring/control
  • Conductivity (Salinity) monitoring/control
  • Oxygen monitoring/control
  • Humidity monitoring/control
  • Air temperature monitoring/control
  • Measurement of KH or Alkalinity (Coming soon)
  • Universally switchable inputs: For pH and ORP; inputs are already compatible for future ion-selective electrodes (e.g., Ca)
  • Galvanically isolated sensor inputs: For high measurement sensitivity
  • Sensor life monitor: Automatically records total operation hours for all sensors; can be reset as needed.
  • Menu-guided calibration for all sensors and probes.
  • Sick fish therapy program: 
    Some fish diseases require a temporary water temperature adjustment. ProfiLux can be programmed to slowly lower the temperature for a set-time. Normal temperature is automatically set after an adjustable time.
  • Universal analog and digital inputs
  • Level functions: For level sensors, leakage-sensors, automatic water change functions, etc.
  • Flow (stream) pump control

Versatile Pump Control


  • Independently control up to 16 stream pumps
  • Wide selection of flow modes: High/low tide, Surge, Random, and much more
  • Variable wave duration: Program wave times from 0.4s…60s in 10 ms steps
  • Programmable random-wave length and intensity
  • Various wave mode options: Sine wave, right-angled wave, short right-angled wave
  • Nocturnal flow: Programmable flow decrease within a desired time range
  • Thunderstorm mode
  • Feed pause adjustable: Programmable pump behavior during feed pauses
  • 3rd party pump compatibility (Tunze®, Hydor Koralia®, Abbyzz®, Royal Exclusiv®, EcoTech®, as well as all pumps with a 1-10V interface)
