1.8 Cable Connection
When installing the ca le connections, the user needs to pay attention to
the safety regulations. Always pay attention to the connection to the
protective earth ground! Pay attention when connecting with other
devices, that those have to e of the same earth potential (same heavy
current/voltage side).
1.9 Ventilation
The equipment must e installed in so that good ventilation to the device is
ensured. Do not put any covering o jects on the device, such as newspapers, ooks
or towels.
1.10 Water and Moisture
The device is not allowed to operate in close vicinity of electrical
conductive liquids or moist areas. It is not allowed to place any liquid
things on the device or in the near y area of the device.
Attention: Danger of Electric S ocks!
1.11 Temperature and Heat
The operating temperature of the device is defined in the specifications. The device
must not e placed near things which produce heat such as to lowers, heaters,
furnaces or other devices.
1.12 Opening t e Device
Disconnect t e mains plug before opening t e device!
There is a risk of electrical shock when touching the parts inside the
device. It is not permitted to make any changes in the device.
Page 6

1.13 Cleaning
Do not use any volatile solvents such as alcohol, diluents, gasoline etc.
to clean the device. Only use a dry, clean cloth.
1.14 Unusual Smell
If any unusual smoke or smell occurs, immediately switch off of the
device and remove it from the main power supply! Contact your dealer
or the manufacturer.
1.15 Fuses
T e replacement of t e fuses in t e device is only permitted by
trained and aut orized tec nical staff.
The change of the fuses is only allowed when the device is switched off
and is removed from the main power supply. Otherwise there is a risk of
electric shocks. The security functions and safety values are mentioned
in the manual. The guarantee for this equipment will expire in case of
using other fuses than those specified in the manual.
1.16 Repairing
The user is not allowed to perform the maintenance work y himself, except for
those specified in the manual. All maintenance and repair work must e done y
trained and authorized technical personnel.
1.17 Important notes on safety
Special Safety Instruction
Please, read and follow safety instructions carefully before assembly or using
t e device!
During installation and when working with 230 V ~ mains supply the VDE
regulations must e followed. Equipment using a 230 V ~ supply may only e
installed and commissioned y a qualified tradesman. The assem ly place must
allow all possi le safety precautions when laying the attached ca les.
Page 7

Power supply ca les and data ca les may not e damaged or squeezed for any
reasons. Plan the assem ly place so that you can reach the mains plug easily and
unplug it from the electrical outlet in dangerous situations.
Choose the assem ly place so that children cannot play or e near to the device and
at its connections without supervision.
Before opening the device disconnect it from the mains supply (unplug) otherwise
there is a serious danger of an electrical shock.
Fuses may only e replaced with standard-compliant parts with the same nominal
value.
All lia ility is excluded for damages which result from non-compliance of these in-
structions or from an improper handling of the device. At chosen intervals in this
hand ook we will give directions for safety precautions. These safety precautions
have een specially marked.
2. Description and intended use
The AquaControl+ is an electronic water management control system.
It has een developed especially for rain water usage systems. It can e used with a
wide variety of tank systems.
Tanks made from metal or steel reinforced cement may only e used when the fol-
lowing conditions have een correctly followed.
Metal tanks lead to faulty readings. Helpful is to assem le the device so that the
sensor is as far as possi le from the metal sides so for example, in the centre of a
cylindrical tank. The system controls offer an easy to use guide for the switch pro-
gramming. Using an LCD display the fill measurement is shown in 1 % stages (in
relation to the height of the tank).The sensor operates with a 12 volt supply. All
programmed values such as the tank height are retained after disconnection of the
power supply or after a power-cut.
3. Description
Performance features:
–Fill level measurement readout in 1% steps and with an additional ar
type indicator
–In 1% steps freely varia le choice of the switching points for the
drinking water refill
–Automatic flushing of the system (choice of intervals in day and time
are possi le)
–Dialogue oriented user guidance (choice of language)
–Equipment indication using 3 additional LED
–Supervision of the measurement pick-up and the sensor
–Error indication in simple text

Note:
Only the control electronics in the device are protected by the fuse. Valves
and pump connections are not protected. These are protected only by the
mains supply via the mains fuse.
The yellow LED indicating Drinking water operation”[3] is lit as soon
as the valve switches over to the mains supply. The user is made aware
that the system now uses water from the mains supply. The red LED for
Faults and malfunctions” [4] is lit as soon as the system identifies a fault. The
display will then show a warning that describes the cause of the fault in plain text.
4. Assembly
4.1 Control system
The mains plug of the device serves as an on / off switch.
Before opening t e equipment pull t e plug out from t e mains
socket!
–Loosen the fastening screws of the lower cover [6] and remove the cover
–Mark out drilling points and drill according to sketch
–Fasten the device with the enclosed installation material (rawlplugs and screws)

4 .2 Connection sensors and data cable:
The sensor electronics comprise of a stainless steel pro e [22] with a red and a
white connecting ca le [27] and the sensor measurement pick-up [28].
Figure 4: Sensor technology
1. Now the sensor measurement pick-up [28] (cover removed) should e
installed on the tank wall (prefera ly in the man hole shaft of the Graf
synthetic tank). The location of the mounted sensor pick-up should e
etween 10 and 15 cm a ove the overflow [25]. The enclosed screws
should e used to secure the device. After fully tightening the screws, the
points that are showing themselves on the outside of the tank must e
lunted to avoid injury [24].
2. Measure the height from the ottom of the tank [23] to the end of the
terminals [15] and [16] on the measurement pick-up [28].
3. Shorten the connection ca le to suit the measured height.
4. Connect the sensor ca le to the sensor as descri ed in the following
instructions: Remove etween 5-7 mm of the insulation from oth of the
ca les. Next, pass the red ca le through the screw mounting 1 [19] and
