This manual complements the “Operating and installation manual” for
the model aquaduct 360 XT mark III and aquaduct 720 XT mark III
Strictly observe the safety precaution and care instructions included in
that manual!
Considering the fast technical development, we reserve the right to be
able to perform alterations to the products at any time It therefore is
possible that your product does not correspond precisely to the descrip-
tions or especially the illustrations in this manual

The aquaduct control unit can be configured
to supply a generic rpm signal This rpm sig-

case of an error and therefore allows for an
extended error management If this connector
is connected to the CPU fan connector of the
motherboard of your PC, depending on the
BIOS an emergency shutdown function can
be realised For detail on BIOS setup, please
consult the manual of your motherboard

The following picture shows the possible connections of the “aquaero
power connect“ cable The standby power supply is to be connected to
the appropriate connector of the aquaduct The green ATX PS_ON#
line can be cut through and connected to the “relay” connector of the
aquaduct If you want to
use the relay outlet for con-
nection to the power switch
line of the motherboard, the
ATX PS_ON# line must re-
main intact! For correct op-
eration, the cable has to be
connected to the power
supply ATX connector and
to the ATX connector of the
motherboard as well

After all connections to the PC interface circuit board have been estab-
lished as described in chapter 2, you can put the aquaduct to operation
following the instructions of the operating and assembly manual, chap-
ter 10
After switching on the computer, the aquaduct will show a greeting
screen with information on the firmware revision before it continues on
to the status of the fans and sensors
You should now familiarize yourself with the functions of the device be-
fore you perform the setup of the basic settings

The aquaduct 360/720 XT mark III features a rotary knob with push
function Using this knob, all functions of the aquaduct can be accessed
and configured Using the USB interface and the included software is

for quick efficiency adjustment
For quick adjustment of the cooling efficiency, the aquaduct 360/720
XT mark III features a configurable override function to adjust all impor-
tant control parameters just with one single movement of the rotary
knob To change the override setting, simultaneously push and turn the
rotary knob
First value: Shifting of target temperatures
The first value is the target temperature shift in °C A value of “-5,0 °C“
for instance means that a sensor configured to have a target tempera-
ture of 35,0 °C will effectively be interpreted as a target temperature of
30,0 °C
Prerequisites: The override function is enabled for the respective sensor
and the fan(s) assigned to this sensor are configured to target tempera-
ture mode, linear or progressive mode
Range of adjustment: -10,0 °C to +10,0 °C
Second value: Shifting of fan output power
The second value is the fan output power shift or rotation speed shift re-
spectively in percent A value of “+20 %“ for instance means that a fan
configured to run at 50% will effectively be powered by 70 %
Prerequisites: The respective fan is configured to manual power configu-
ration or in fixed rpm mode and the override function is enabled

and a underscore marks the first character By turning the rotary knob,
the first character can be changed The characters appear in the follow-
ing order: capital letters, lower case letters, space, and numbers By se-
lecting the character ““, the cursor jumps back to the previous posi-
tion
After confirming your selection by pressing the rotary knob, the cursor
will move on to the next character Repeat the procedure for all charac-
ters After confirming the last character, the aquaduct will show the

ciple of assigning sensors to fansciple of assigning sensors to fans
ciple of assigning sensors to fans
As a basic principle, fan regulation parameters such as mini-
mum/maximum temperature and target temperature are defined for
each temperature sensor, not for the fans This means that you will have
to configure the temperature sensor first and then assign this configured
sensor to one ore more fans
One or two temperature sensors can be assigned to each fan, alterna-
tively each fan can also be manually controlled

is
Depending on the set regulator option this parameter has the following
effect on the regulated fan:
Regulator option “linear“ or “progressive“:
Simply put, the hysteresis is the difference between the start-up and
shutdown temperature for the fans A frequent start-up and shutdown of
the fans is therefore prevented if the current temperature fluctuates
around the start-up temperature Should the fans be turned on and off
in short intervals you should increase this value
Regulator option “target value“:
If the fan is regulated via the target temperature, the hysteresis defines
the tolerable temperature aberration, meaning that the fan speed will
not be adjusted as long as the temperature does not differ from the tar-
get temperature more than the hysteresis value

AQUADUCT CONTROL UNIT

Gelliehäuser Str 1, 37130 Gleichen, Germany
If for instance a target value of 35 °C and a hysteresis of 1 °C is set,
then the rpm of the fan is only adjusted when the temperature rises
above 36°C or drops below 34 °C

The higher this time, the slower the temperature regulator reacts to
changes in temperature which means that the corresponding fan adjusts
the rpm slowly For instance when regulating an inert system like the wa-
ter temperature in a cooling system, it would be useful to set this value
to approx 20 seconds
This value mainly determines the regulatory behavior at small tempera-
ture differences; at larger temperature differences, the effect from the
regulator factor becomes ostensible
Default value is 20 seconds for “Water in“ and 3 seconds for all other
sensors

nected fan is determined automatically when the system is started If the
connected fan does not generate any speedometer signal, the selection
is deactivated If you connect fans during operation, you can let the
aquaduct determine the parameters again, see 8 5 Get maximum rpm
When activated, the aquaduct regulates the fan after the speedometer
signal has been reported back and adjusts the power output load-
dependently Only when the entered speed can not be reached even at
max power, the fan will slow down

Allows the switching between a linear and a progressive speed-curve in
the temperature-controlled operation or activates regulation via a tar-
get-temperature
"Linear" and "progressive": linear means that the fan is regulated propor-
tionally between the start-up temperature and the full load temperature,
while at progressive regulation the speed-curve is dependent on the
temperature With climbing temperatures the speed-curve begins shal-
low but climbs steeper as the full load temperature is reached
Opposite to the linear regulation, the fan performance in progressive
regulation is mobilized only in the upper temperature area and a quieter
operating sound is made possible at a lower heat load However at
higher temperatures the full load of the fans is still reached rather
quickly
Sensor parameters used: "start-up threshold", "full load threshold" and
"hysteresis"
"Fixed": the fan is regulated so that the target temperature is held con-
stant if possible For this purpose the sensor parameter "target tempera-
ture" is used
Sensor parameters used: "start-up threshold", "full load threshold", “con-
troller delay”, “controller factor” and "hysteresis"
