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

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
Page 10

tighten this lightly, then connect the red ca le to the terminal [16]. The
free white ca le is now passed through the screw mounting 2 [18] and
tightened lightly, then connect the white ca le to the terminal [15].
5. Now pass the end of the data ca le that has no plug connector [12]
through the screw mounting 3 [13]. Lightly tighten the screw mounting
and connect the ca le wire cores of the data ca le [12] to the dou le
terminal [14]. The connection of the data ca le is reverse polarity
protected. Attention! T e screws s ould be tig tened wit care to
ensure t at t ey are not damaged t roug over tig tening.
6. Now recheck that all the screwed items and the sensor components have
een fitted correctly. Replace the cover of the measurement pick-up and
secure this with the appropriate fastening screws.
7. The installation of the data ca le [12] to the system control must e
according to good professional practice to constitute a correct completion
of the sensor technology: A protective ca le conduit must e used. (The
data ca le is not suita le for installing directly in the earth).
The end of the data ca le that is still unconnected is fitted with a plug
connector. This is to e plugged into the appropriate socket [7] of the
system control. Diagram 2 on page 3 makes clear the interrelation:
Note:
The red and the white cable going down to the probe should be straight
and smooth to be drawn taught by the weight of the stainless steel probe.
The stainless steel probe must hang just above the tank floor.

4.3. Electrical wiring diagram
The AquaControl+ offers the rain water system a dry run protection for the pump
or the house water system. So that the dry run protection will function properly the
rain water system must e wired according to the following diagram.
Figure 5: electrical wiring diagram
Note:
Should the existing pump or house water system already have a dry run
protection it may be appropriate and is possible to order the
AquaControl+ without a dry run protection.
4.4 Connection of t e solenoid valve
Connect the plug of the solenoid valve with the centre coupling [8] of the control
electronics (see figure 1).

7. Error messages and fault correction:
T e operation of t e system control is to be c ecked at regular intervals (at
t e latest every 4 weeks).
The read out reports always represent only pro a ilities; e.g. no clear localization
y the device is possi le for overlaying faults.
Please also take note that the system control device cannot identify any
malfunction of the house water system. (No malfunction signal is supplied
by the house water system to the system control device).
If faults are recognized y the sensors the system control cannot continue to work
independently.
The particular faults are shown on the plain text in the display:
Page 18

For further diagnosis, remove the stainless steel
weight [22] out of the water. If the error indication
has now stopped, then the sensor it self was the
cause of the fault. If the error indication should
continue, this implies that the measurement pick-up
is defect.

Figure 13: Error messages
If the device shows no function at all then check whether the main electrical supply
provides current and also check the house fuses.
Before opening t e equipment pull t e plug out from t e mains
socket!
If the electrical outlet is under current, then unplug the mains plug from the system
control. Without connection to current open the lower cover of the system control
(see Figure 1) and check the equipments mains fuse.

trol.
8. Upgrade options:
The SILENTIO control device can also e equipped with a num er of additional
special functions.
1. Optional pressure sensor
Using a pressure sensor, alternative mediums or depths
may e adapted to the use of the device. The sensor must
e matched the required specifications of the device.
2. Optional drain pump
If the fill level of the tank reaches a specified value, then
a valve or a pump can e activated. This is to prevent the
fill level of the tank from exceeding a specified
maximum level.
3. Optional refill
If the fill level in the main tank sinks elow a specified
level, then a second tank is employed to ack up and re
fill the main tank. The pump used in this process must
also e equipped with a mechanism to prevent it from
running dry.
If this system is required, then the device must e sent to the manufacturer. There
follows an additional calculation.
Note:
The standard system control device may be equipped with a maximum
of three additional switch output point.
