The feed mode offers 3 possibilities, which are shown in the upper line of display to the right of the feed digits 1-4:
No arrow = The time is stored but no feeding occurs
1 arrow = The feed container rotates once.
2 arrows = The feed container rotates twice with a 1 minute interval. This extends the time interval for feeding without engaging additional feeding times.
General programming rules:
MODE switches initially between the current time and the feeding times 1 to 4 consecutively. The current time is displayed whenever you see the blinking double point; the feeding times are differentiated by the digits (1-4) on the upper section of the display.
SET allows the respectively displayed times to be changed. With MODE, the displayed time can be changed between hours and minutes, and feeding mode. The respectively effected symbol (either time or feeding mode) blinks and can be set to a higher number with the "+ button". SET stores the respective time, which has been set, while reverting back to MODE the next feeding time is displayed.
Example:
After the batteries have been inserted, the time begins at 00:00, and the double point blinks at one-second intervals.
The current time is set:
SET > Hours blink and are set with +.
MODE > Minutes blink and are set with +.
SET > Current time is stored.
Programming feeding time 1:
MODE > Feeding time 1 is displayed with 00:00 and the digit 1 on the upper section of the LCD.
SET > Hours blink and are set with +.
MODE > Minutes blink and are set with +.
MODE > Digit 1 blinks, the feeding mode must be set with +.
SET > Feeding time 1 is stored.
MODE > The next feeding time is displayed. This can be programmed as above through SET, or when the MODE button is pressed repeatedly, it switches through the further feeding times back to the current time.
Manual Operation
For feeding outside the programmed times, press the "manual feeding" button, which allows the rotating of the container to be triggered manually.
Filling
Take out the container unit lengthwise and remove the cover on the back. Clean the drum, ensuring it is dry, and fill the amount of feed. Afterwards, place the cover back on and insert the drum unit onto the axis. The automatic feeder is suitable for flake food and granulates. Do not use for fresh or wet feed?
Feeding amount
By adjusting the slider, the container opening can be varied in order to dose the amount of feed as required. For larger amounts, the programming can be done at an interval of two times in a row.
Positioning:
Place the automatic feeder on the aquarium cover so that the feed can fall freely to the surface of the water. The drive unit with its reverse air-intake opening must not be located in the humid-air section o the open aquarium. Do not cover up the air-intake opening.
In some aquarium covers, a corresponding feed opening has already been provided. EHEIM professionel covers can be supplemented with the automatic-feeder module order no. 60 7020, which guarantees an optimal positioning.
