2. Safety Instructions
The installation, operation, maintenance
and repair personnel must have the neces-
sary qualifications for this work. The
owner/operator must clearly define respon-
sibilities, accountability and monitoring of
the personnel.
Operating safety and reliability of the sup-
plied system is only guaranteed for its pro-
per intended use. The limit values given in
the technical specifications must never be
exceeded.
This system contains electrical voltages and
controls mechanical system parts. Failure to
follow the installation and operating instruc-
tions can result in substantial property da-
mage, physical injuries or even fatal acci-
dents.
The accident prevention regulations, rele-
vant DIN and VD standards and guidelines
as well as the regulations of the local power
supply company must be complied with du-
ring installation, operation, maintenance
and repair of the system.
The system is part of another, overall sy-
stem. You must therefore also note and fol-
low the operating instructions for the whole
system and the individual components.
ach time any installation, maintenance, in-
spection or repair work is carried out on one
of the components the whole system must
always be shut down and secured against

The two "▲" and "▼" buttons are used to sel-
ect set points and set values.
Ultrasound sensor (19)
The ultrasound sensor measures the water
level in the tank.
The Aqatronic K switching device is used to
control drinking water top-up and level mo-
nitoring for KESSEL Aqabull and Aqadive
rainwater pumping systems.
The difference between the two systems is
the type of drinking water top-up and the lo-
cation of the pump.
With the KESSEL Aqabull rainwater pum-
ping system the water is topped up as and
when necessary via a separate top-up sup-
ply tank. The pump is located outside the
tank. With the KESSEL Aqadive rainwater
pumping system the top-up supply is fed di-
rectly into the tank. The pump is located in-
side the tank.
Note:
If the Aqatronic K switching device is
purchased without the rainwater pumping
system the switching device is in the Aqabull
basic setting.

Important!
To be connected by a qualified electrici-
an only. Comply with the relevant, cur-
rently valid regulations, laws and stan-
dards. Also read and follow the "Safety
Instructions" chapter. The seals of the
cable glands which are not used, i.e. no
cable is connected through them, may
not be penetrated. They help to seal the
housing.
The connection lead of the ultrasound sen-
sor must be connected in accordance with
the circuit diagram (see next page). First,
use a screwdriver to push through the cable
gland seal concerned (Figure a), feed
through the cable (Figure b) and connect
(Figure c).
Then tighten the nut of the cable gland by
hand (Figure d).
Note the technical specifications when
connecting the drinking water top-up supp-
ly, outputs 1 and 2, the floating contact and
the leakage probe. Use products approved
by the manufacturer only. Otherwise the
above text applies.

Note and follow the "Safety Instruc-
tions" chapter!
If all the electrical and mechanical compo-
nents have been properly connected, the
system can now be put into service.
 Plug the mains plug into the earthing
socket.
 The switching device displays the cur-
rent version number.
 Soon after, "HHH" appears.
 Press the "T" button
 020" appears in the display
 An acoustic signal is emitted.
 Use the "▲" and "▼" buttons to set the tank
height in cm.
 Press the "T" button for more than 2 se-
conds to confirm the value.
 An acoustic signal is emitted.
 Value has been saved
The device is in normal operation. After a
short time the current water level is display-
ed in cm. The green L D for normal opera-
tion is lit. The device is running with the de-
fault factory settings. These are shown in
the table "5.4 Default factory settings"
7.2 Normal operation:
In normal operation, the switching device
compares the water level in the tank with
the set switching points. If there is sufficient
water in the rainwater tank (water level
above the USP) the system runs in rainwa-
ter mode, i.e. when a fixture (i.e. toilet, fau-
cet) connected to the service water system
is opened, rainwater is pumped into the
pipe network. If the water level falls below
the USP, the drinking water top-up is auto-
matically activated until the water level has
reached the OSP. Activation of the drinking
water top-up is indicated by the orange drin-
king water top-up L D.
7.3 Manual drinking water top-up
( WvH)
The "T" button can be used to switch on
drinking water top-up (TWvH). TWvH auto-
matically switches off after a defined time.
The TWvH time is stored in set point 02
and can be changed at any time. During
TWvH the remaining time in minutes ap-
pears in the display. The decimal points of
the display flicker and the orange drinking
water top-up L D is lit. The TWvH can be
switched off manually at any time.

7.4 Other functions:
a) Backwater switching point
This has a different effect on the drinking
water top-up depending on the two system
types:
Aqabull:
Drinking water top-up is switched on auto-
matically. The non-potable water system is
supplied directly from the drinking water
top-up tank until the error is acknowledged
at the switching device.
Aqadive:
Drinking water top-up is blocked until the
error is acknowledged at the switching de-
vice.
b) Rainwater filter rinsing
The rainwater filter is rinsed at regular in-
tervals. Activation of this function and the
times for the rinsing interval and duration
can be set as required. Rainwater filter rin-
sing can be switched on manually at any
time.
c) Detection of leaking water
If the leakage probe detects water, the
drinking water top-up, output 1, output 2,
the floating contact and the acoustic alarm
are affected according to the selected set-
tings.
d) he floating contact
The floating contact is used to signal a
mains power failure or error.
e) Sensitivity of the ultrasound sensor
The sensitivity of the ultrasound sensor
can be adjusted to match the installation
conditions.
