Adjusting brightness
You can adjust brightness individually: Adjust the maximum
brightness by pressing the keys "+" and "-". The automatic
dimming process also ends at the brightness adjusted
here. You can adjust different brightness levels by press-
ing "+" for a long time, and you can also reach other posi-
tions stored with 100% brightness. These depend on the
system. In case you stored one of these positions and lat-
er on wish to reduce the brightness, you may need to press
the "-" key for a longer time to reduce the brightness in
visible steps.
Attention! Before using at the aquarium or in case of appar-
ently insufficient brightness inside the aquarium in spite of
sufficient LED equipment, first check whether the maximum
brightness of the dimmer is adjusted correctly, and correct
if required.
Adjusting the actual time
Press the "SET" key for approximately 3 seconds. The dis-
play will then start to flicker. Then press the "HOUR" key (for
adjusting the hours) and "MINUTE" (for adjusting the min-
utes) to set the actual time. Pressing these keys will increase
the displayed digit by "1" every time. If keys are held down,
the numbers in the display start to run upwards quickly.
Adjusting the sunrise time
After adjusting the actual time, press the "SET" key. Now
"ON" is displayed for the sunrise. The display changes to in-
put mode immediately afterwards. The beginning of the sun-
rise can be adjusted by the "HOUR" and "MINUTE" keys as
desired (see adjusting the actual time).
When choosing one of the F5 – F7 modes, the beginning of
the sunrise should be set sooner than 12:45.
Adjusting the sunset time
Press the "SET" key again. Now "OFF" is displayed for set-
ting the sunset time. The display changes to input mode im-
mediately afterwards. The beginning of the sunset can be
adjusted by the "HOUR" and "MINUTE" keys as desired (see
adjusting the actual time).
When choosing one of the F5 – F7 modes, the beginning of
the sunset should not be set sooner than 15:15.
We recommend leaving on the diurnal lighting a half hour
longer when using F5 – F7 for planted aquariums.
Adjusting the switch mode
You can adjust the switch mode (F1 – F7) by pressing the
"SET" key again. You can choose between the following pro-
grams:

F1
Sunrise/sunset

F2

F7

Pressing the "HOUR" key repeatedly switches the programs
in the order F1, F2, F3, F4, F5, F6, F7, F1, F2 ... etc.
During the programs F3 and F4 the light is reduced to 10%
or 30% of the adjusted light brightness, respectively. This
takes place for slightly over a minute every 20 or 15 minutes,
respectively. However, these cloud scenarios only begin one
hour after sunrise. Confirm the settings with pressing "SET".
This will put the dimmer back in operation mode.
Reset function
Press the key "MINUTE/ON/OFF/RESET" for 3 seconds. This
resets the unit to default settings.
Demo Mode
Press the "HOUR/F1 – F7/DEMO" key for approximately
3 seconds. Now sunrise and sunset will be performed with-
in 75 seconds with one cloud simulation. After finishing, the
dimmer will return to operation mode.
Power supply
Should the sera LED Digital Dimmer be disconnected from
power supply for minutes or longer, the stored data will be
lost and need to be entered again.
Advice
It is impossible to influence the brightness by any manual ad-
justments while dimming processes are running. Manual dim-
ming procedure adjustments can be done only after finishing.
Functional effects
Depending on the combination of LED tubes connected to
the sera LED Digital Dimmer, there are different illumina-
tion scenarios. For instance, the "sunrise" tube will start first
to simulate the sunrise.
