Operation manual for
Aquarium Computer AT Control
AT Control is a measuring and control system with nearly unlimited possibilities for the electronic control
of aquariums and terrariums. The basic version comprises a temperature controller, multiple timer
functions and a PC connection for programming and data display. Optional accessories are a pH
control, Redox (ORP) control, density control (for marine aquariums), conductivity control (for pure and
freshwater) and a level control. The parameter can be connected and the set points can be adjusted as
fix points or as a curve in the day-night-cycle. The complete programming can be made from the
Controller or directly from the keyboard of the PC.
1. Description of the system
The aquarium computer AT Control is a modular system. Starting from a basic unit, it can be enlarged
almost indefinitely.
The minimum for starting is the AT control set and one Power Box. Interface Boxes (for measuring of
pH, Redox (ORP), conductivity, density and level) can be added. If more mains sockets are needed,
more Power Boxes can be added as well. All system components are connected by USB connectors. A
USB Hub can be used to multiply these connections, if more, than the supplied 8 are needed.

2. Connection.
At first the batteries are placed into the controller (1) and the USB cable is connected,
before the lid is closed. Then all components are secured safely near the aquarium.
The Power Box (2) and the Controller (1) can be clipped into the holders, the Interface
Boxes (5-8) can be fixed to smooth surfaces with Velcro.
All components are now connected with the Power Box using the USB cables.
The temperature sensor (10) and if included the level sensor are directly connected
with the Power Box, using the audio jacks between the USB plugs. If more than 2
temperature or level probes are
used, an additional T/Lv- Interface
Box is needed.
All other probes are connected to
their corresponding Interface Boxes.
To reach the sockets, the Interface
Box can be opened and the sensor
can be connected to the plug. If
closed again, the sensitive
connections are protected.
Foto 5: Interface Box
If all internal connections are done, the Power Box can be connected to the mains.
The unit is switched on . One after the other, the connected sensors and components
are recognised by the controller. By pressing the Enter button, the components are
activated. Now, the corresponding measuring values are already displayed.

5. Connection of the AT Control to a PC
For the connection of the AT Control to a PC, an IBM compatible PC is needed.
The PC Interface is connected to the Power Box with the USB cable that is included in
the Interface Box. A standard USB cable, up to 10 m of length may be used as well.
The serial connector of the Interface Box is now connected to the corresponding
socket of a PC or laptop. If the Computer is not supplied with a serial connection, the
USB adapter can be used to connect the Interface Box with the USB socket of the PC.
Now, the AT Control Software has to be installed on the PC, from the delivered CD. If
the USB adapter is used, the USB software from the 2 nd CD has to be installed as
well.
The program creates an icon on the desktop. After the start of the program, the display
shows at the lower edge: “not connected”. At the upper edge of the display, a row of
icons is placed, among the AB logo. By pressing this button, the connection between
AT Control and PC via performed. Make sure, that the AT control is showing the basic
screen with the measuring values. If other screens are active, the connection is not
successful. The rest of the programming is self explaining and explained in a special
manual.

Temperature control with the AT Control
The AT Control is supplied with a very comfortable temperature control program, with almost
unlimited possibilities. Several heaters or cooling devices can be connected to one sensor and operated
individually. The set point can be varied in the day-night cycle, which a night shut down
Examples: Gravel Heater for planted aquariums. The Gravel Heater (cable heater) can be adjusted to a certain
set point (e.g. 25°C). As the gravel heater is not designed to be the only heater for the aquarium, an
additional water heater (Titanium or glass heater) can be added. This will be programmed to a lower set
point, so the gravel heater is always preferred.(e.g. 24°C). It should be made sure, that the gravel
heater is active in summer, at least from time to time, to keep the nutrient cycle in the gravel running. In
order to ensure this, the menu “summer function” can be activated in the Power Box to the plug of the
gravel heater. For both heaters (Gravel heater and water heater) a night shit down of 1 – 2 °C can be
programmed.
Temperature control for reptiles in Terrariums. Here the night shut down is of even more
importance, than in aquariums. During the day, a heat lamp or hot stone can be used as heater. During
the night, the temperature is actively decreased – by a fan or a water cooler.

plugs is for the cooler, the lower line for the heater.
To program a heater on plug 2 press the arrow key↓. The
thermometer icon appears above plug 2, lower line. – The cooler
can be programmed in the same way: choose a plug, confirm with↑.
Now the thermometer icon appears above the no of the plug in the
upper line (here No5). Now a heater can be connected to plug 2, a
cooler to plug 5.
Temperature curve in the day-night cycle - night
shut down.
If the set point shall not remain constant in the day-night-cycle, a
temperature curve can be programmed. This is of special
importance in terrariums. But in aquariums, a night shut down of
1.5. - 2 °C gives often positive effects, too.

Data Record
In this way, you can create e curve, - the cursor is shown as
triangle, with the corresponding temperature and time. In the
example, the temperature at 20°° (8pm) is decreased for approx. 2 °
- compared with the temperature in the afternoon. You can save the
edited curve with Enter. The AT Control will now use the curve as
set point and switch the heater and the cooler in a way that the
actual temperature is close to the curve (+/- the edited hysteresis).
Leave the screen with ESC and you go back into the main menu.
If a temperature menu shall be edited, choose “show/modify”
delete” in the temperature menu. The program can now be edited.
