2025-03-22 00:00:00 Aquarium controller can do many repetitive aquarium maintenance jobs: Control LED lighting. Four channels available so you can control four different colors LEDs manually or automatically. In manual control mode user can turn LEDs off or on; when LEDs are on, LED brightness for each channel can be set from 0% to 100%. In automatic control mode controller can change LED brightness uniformly through a selected period of time. This means you can simulate sunrise, sunset or moonlight effects when LEDs are uniformly dimmed for example from 0% to 100%. Also LED brightness can be set to stay constant through a selected period of time. Controller has LED temperature sensor. This sensor can be attached to LED radiator. Sensor will measure radiator temperature. User can set temperature limit when controller will activate cooling fan to cool-down radiator. Turn off/on automatically high voltage (120-230V AC) devices, like water filter, air pump, CO2 valves, aquarium fluorescent or metal halide lights etc. Eight channels available. Each channel has inbuilt separate timers which have 1 minute resolution. Timers allows to turn on/off aquarium devices several times per day. Also manual control available where you can turn on/off channels manually. Aquarium water temperature is measured using water temperature sensor. Controller will activate water heater or cooling fan block when water temperature drops down or rises. Thus controller will support constant aquarium temperature, set by user.
