Dennerle Trocal LED Control User manual

Quick start:
Trocal LED Control & GHL Control
Center
Please install the latest version of the software "GHL Control Center" on your PC
Https://www.aquariumcomputer.com/de/downloads
The GHL Control Center, hereinafter mentioned as GCC, assists you in the convenient programming
of your LED control. The GCC allows among other things the backup and restore of individually
created illumination curves and device settings. Please note that some functions mapped in GCC may
not work with the device due to the limitations of the display and conversely device-specific
functions such as the time-lapse function can only be set on the device itself.

1. How to connect the Trocal LED control
Connect the power adapter of a "Trocal LED" with the LED Control by means of the cable “LED Connect"
and connect it to a power outlet. You can now establish a connection to the PC via the included USB
cable.
Note: The DENNERLE Trocal LED control can only be programmed with the PC software "GHL Control
Center (GCC)" if the device has at first been connected to the PC via the USB connector and before
opening the application.
1.1 Now open the GHL Control Center
1.2 When first opening the GCC, the following error
message appears: "Connection failed. Would
you like to check settings now?” Choose “Yes” in
the Popup
1.3 In order to connect the DENNERLE Trocal LED
Control automatically with the GCC after
program start, please activate the check box in
the line "Dennerle Trocal LED control" and
"Establish standard connection automatically
after program start"
Confirm with “Close”:
1.4 You can now connect the DENNERLE Trocal LED
Control with the software by double-clicking on it
in the side bar.
Please note: These steps are only necessary the first time you are establishing a connection. The next
time the program is started, the connection between the DENNERLE Trocal LED Control and GHL Control
Center will be established automatically.

2. Illumination
In the GCC , up to 2 Tocal LED lights, each with 2 separate channels (i.e. a total of 4 channels) can be
programmed independently of each other.
Channel 1 and 3: Warm white; 4,000 K - Channel 2 and 4: Cool White; 6,500 K
2.1 In the sidebar, select an “illumination
channel”.
In the following window up to 8 dimming
points can be set.
2.2 Select and then enter your
desired time and brightness in the
window.
Confirm with
Note: The brightness at the start point
and end point of the illumination run
must always be set to 0%!
2.3 Repeat step 2.2 until the illumination run
corresponds to your wishes.
Tip: For a moon light setting select the
colder illumination channel 2 or 4.
2.4 To save the illumination run, click
in the menu.
The illumination run is then transmitted
to the device.
2.5 Repeat steps 2.1 to 2.4 for the other
illumination channel(s).
Tip: If you are not sure what the optimum illumination run for your aquarium should be, you can find
some examples in the instructions manual of the DENNERLE Trocal LED Control. In the graphical
representation of the illumination curve, it is possible to change the previously programmed
illumination points comfortably with the mouse pointer. Please note that changes only take effect
after saving.

3. Acclimation
The function "acclimation" offers a simple and convenient way to adapt the intensity of the
illumination automatically over several days. This is especially important for the plants in order to get
accustomed to the new and often much stronger light. Also newly added animal residents (fish, corals
etc.) benefit from a gentle increase of the light intensity.
3.1 In the sidebar, select “Acclimation”.
3.2 In order to enable the acclimation, select the
check box .
3.3 Select a start date. The acclimation starts
immediately and runs with the set value.
3.4 Select an end date. The acclimation ends on this
day.
3.5 Click on to save the acclimation
run.
The settings you made are transferred to the
device.

4. Simulation
Under this menu item you can set the period of the active moon phase simulation. This moon phase
simulation does not "create" any moonlight, it influences the curve for the moonlight programmed in
the illumination channel. The moonlight now corresponds to the current natural moon phases.
Accordingly, at new moon e.g., no moonlight can be identified.
4.1 In the sidebar, select “Simulation”.
4.2 Select the start time and the end time in
which the moon phase simulation should
be active.
Ideally, this period of time corresponds to
the setting curve for the moonlight in the
illumination run.
4.3 To save the moonlight run, click
in the menu.
The settings made are transferred to the
device.
4.4 For activating the moonlight you must
select the check box “Depends on moon
phase” in the corresponding illumination
channel.
