Page 3: Introduction
Introduction 1.1 Safety instructions All electronic components of the aquarium computer must only be operated in sound condition. If the feeder is damaged please have this replaced by a technician or send us the equipment for repair. Continued operation may cause a fatal electric shock. Ensure that the controller (1) and power unit (12) do not come into contact with water. It is good practice to disconnect all electrical equipment from the mains before placing your hands in the aquarium. Hint: It is recommended to use a separate or dedicated, safety-switch protected supply which disconnects the mains from the aquarium equipment in the event of an electrical fault. 1.2 Installation Controller The controller (1) has a mounting recess or slot (2) on the back, which mates with the mounting rail (3), and may therefore be mounted using the screw set, (4) to a wall or the... -

28.0° C due to the summer temperature, cooling is activated. Hint: If it is decided to use the cooling mode of the Multicontrol, it is suggested to retain the significant bene- fits of substrate heating (see 3.1), a heating cable is controlled instead by the water temperature channel. -
Page 7: Temperature Alarm
CAUTION: If no pH electrode is connected to the MultiControl, so that the BNC socket is open, inevitably, ficti- tious pH values will be displayed in individual as well as toggle mode (where the displayed values change from one to the next in a 2 second cycle). -

4. Quick Start Guide to Programming Switch display lighting ‘on’ or ‘off’: Press and hold the ▼ key = on/off. Toggle mode: Temperature and time of day are displayed alternately in a 2 second rhythm (factory preset). Single mode: Optionally either pH value, temperature or time of day are displayed continuously (by pressing the ▲ and ▼ key). Hint: Shall the pH value be displayed in the toggle and single mode, please select “on” when programming the pH set-point in the menu item. -
Page 9: Programming Instructions
5. Programming Instructions First tap “Menu“ key to start the programming mode. Hint: The symbol ”Menu” indicates you are in the programming mode. By holding down “Menu” it is possible to quit the programming mode at any time. Control of Water Temperature When pressing the “Menu“ key, “25.0” flashes on the display. Set the required value with the ▲ or ▼ key. Acknowledge with “Menu” key, “0” will flash. Set the required value with the ▲ or ▼ key. Acknowledge with the ”Menu“ key to return to the main menu. -
Page 10: Setting Temperature Alarm
Setting Temperature Alarm Press “Menu” key, “3.0” will flash. Set the required value with the ▲ or ▼ key. Acknowledge with “Menu”, “Off” will flash. To activate the temperature alarm, set display to “On” with the ▲ or ▼ key. Acknowledge with ”Menu“ to return to the main menu. Scroll to the next menu item with the ▲ key. Setting Switching Times Press the “Menu” key, “1” flashes. Press the “Menu” key to set the switch-on time of the slot, “00:” will flash. Set the desired hour switching-on time with the ▲ or ▼ key. Acknowledge with “Menu” key, “:00” will flash. Set the desired minutes switching-on time with the ▲ or ▼ key. Acknowledge with the “Menu” key, “Off” will flash. Now set switching-off time of slot . Set the desired hour switching-off time with the ▲ or ▼ key. Acknowledge with “Menu”, “:00” will flash. Set the desired minutes switching-off time with the ▲ or ▼ key. Acknowledge with “Menu”, “Off” will flash. Set the day or days with the ▲ or ▼ key. Acknowledge with “Menu”, “1” will flash. If you want to set (up to 7) other switching on/off times of the slot , press ▲ and program in the same way. In order to quit sublevels of switching times of , hold down „Menu“ to return to the main menu. Scroll through to the next menu item 11 with ▲. -
Page 11: Programming Ph Set Point
Setting pH Alarm Press the “Menu” key, “0.5” flashes. Set the required value with the ▲ or ▼ key. Acknowledge with “Menu” - “Off” flashes. Set to “On” if a pH electrode is connected. Otherwise set to “Off” , to avoid a meaningless pH value being displayed in normal or toggle mode if no electrode is connected and the pH BNC socket is open. To activate the pH alarm, set the display to “On” with the ▲ or ▼ key. Acknowledge with the “Menu” key to return to the main menu. Scroll through to the next menu item with the ▲ key. Calibrating pH Electrode 1. Connect the pH electrode to the MultiControl and remove the protective cap from electrode tip. 2. Rinse electrode tip briefly with Dupladest. 3. Press the “Menu” key - “7” appears at the top-left of the display. 4. Dip the electrode into the pH 7 solution. When the displayed measurement has settled, press and hold the “Menu” key (until beep) to accept value; “4” appears at top-left of display. 5. Rinse electrode tip briefly with Dupladest. 6. Dip the electrodes into the pH 4 solution. When the displayed measurement settled, press and hold the ”Menu” key (until beep) to accept value; this will bring you back to the main menu. 7. Rinse electrode tip briefly with Dupladest. 8. Fix electrode in the aquarium with suction cups. 9. Scroll through to the next menu item with the ▲ key. -
Page 12: Setting Calibration Memory
