The new generATion of elecTronic 

sAniTAry fiTTings 

The new AQUA 3000 open water management system provides a wide range of 

automatic water control options even at the fittings level – such as thermal 

disinfection, hygiene flushing and peak-load optimisation – thus offering optimum 

hygiene and economy. 

2

Managing water intelligently 

The new AQUA 3000 open water management system is based on an innovative 

platform of electronics. Due to its state of the art architecture, installers and operators 

will find that the system is now considerably easier, operationally more reliable, more 

functional, hygienic, economical and even easier to incorporate into host networks than 

previous generations of water management systems. 

AQUA 3000 open, the third generation intelligent water management system is now 

subdivided into two levels – fittings and network – which communicate with each other 

via standardised data technology. The most important water delivery functions are 

controlled at the fittings level. The network level, with its' PC and software, provides 

additional functionalities and system expansions. 

At the fittings level, an intelligent electronic module provides a wide range of control 

functions such as time-scheduled hygiene flushing, thermal disinfection, peak-load 

optimisation and saving of system settings. By combining the system with the ECC 

(ECC = Ethernet-Can-Coupler) function controller, additional supplementary functions 

are enabled: automatic thermal disinfection for groups of fittings, shut-off for cleaning, 

individual hygiene flushings, day/night/holiday programs and data recording on an 

optional SD card module. At the network level, innovative software provides the system 

with facilities to centrally control and manage any number of sanitary fittings.

highly inTelligenT fiTTings Technology 

With its intelligent, electronically controlled water delivery functions, the AQUA 3000 

open system can be used wherever hygiene, user convenience and economical operation 

are of prime importance. 

4

Electronic module optimises water delivery functions 

The intelligent electronic module is the core of this new development. Even at the 

fittings level it combines water delivery and control functions that are independent of a 

host control unit or a network control system. 

The factory-programmed electronics module enables easy plug-and-play commissioning 

of the fittings. The electronic module integrated in each fitting is provided with a 

fitting ID that has a function program for all water delivery functions relevant to the 

particular field of application. Additionally, a fixed serial ID assignment provides a 

unique serial number for other overriding control functions such as special disinfection 

programs.

Easy parameter settings: 

Facility-specific program parameters can be set with the help of 

specifically developed system software. Additionally, state of the 

art updating techniques are provided to keep the program 

functions up to date. 

Water delivery functions optimised for specific 

requirements: 

The electronics module automatically controls application-related 

basic functions such as Start/Stop for water flow and flow 

duration. 

Various program modifications, such as individual hygiene flush 

functions and peak load programs, can be set with the system 

software when the system is being commissioned.

Switching program modes: 

All fittings are provided with 2 alternative control programs 

(water delivery functions) backed up in the electronic module. To 

select the different modes, e.g. day/night, school/association, 

paid/unpaid water delivery, classes/holidays, stadium/ 

intermission, room occupied/vacant etc., the respective 

programs can be switched via an ECC function controller or the 

service software. 

Peak load optimizations: 

The peak-load optimization programs are backed up in the 

electronic modules and can be activated with the system 

software. The program for a user-dependent reduction of the 

flow-duration controls water delivery as a function of the

frequency of usage of the fitting. The higher the frequency of 

usage, the shorter the water-flow duration will be made in a total 

of 4 steps. When a large number of fittings are used at the same 

time (for example during intermissions at theatres or stadiums) it 

is also possible to have time-shifted water flow, so called 

suppressed concurrency. 

Automatic hygiene flushing: 

Three control functions specific to the facility can called up with 

the hygiene flushing programs backed up in the electronic 

modules: 

- Automatic hygiene flushing within a fixed interval is performed 

for the fitting (factory programmed to a 24 hour cycle). 

- Dynamic hygiene flushes are performed after a 

fixed period of time after the fitting was last used. 

- Temperature-controlled hygiene flushes are performed in 

conjunction with optional temperature sensors via cold 

and/or hot water temperature control. 

The different types of hygiene flushes are initiated by means of 

the system software. 

Thermal disinfection programs: 

The most important parameters (treatment time within the 

circulation, water flow duration, temperature control) of the 

thermal disinfection process are backed up in the electronic 

module of each individual fitting. The temperature protocols are 

stored there as well. The disinfection measure is started via the 

ECC function controller or a PC. Operators can choose between 

a dynamic temperature-controlled program or a time-scheduled 

disinfection program. Furthermore, the optional water delivery at 

the last fitting in the circuit ensures the speedy flow of hot water 

through the circulation pipe, and the thermal disinfection can be 

performed in a time efficient manner. 

Safety shut-off: 

In the event that a fitting is actuated while a thermal disinfection 

is being conducted, the TD program is interrupted 

immediately. 

In the same way, the safety shut-off also intervenes to switch off 

water flow when, for example, the system is used improperly. 

Statistics functions and temperature protocols: 

Each actuation of a fitting is counted, also the time since the last 

hygiene flush and the last thermal disinfection. 

The electronic module has 3 protocol memories, cold drinking 

water (DW), hot drinking water (HDW) and thermal disinfection 

(TD) for controlling the water temperatures, provided that the 

fitting is equipped with the optional temperature sensors on the 

hot and cold water side. 

The temperatures measured during the last 90 minutes (DW and 

HDW) are saved in one-minute intervals. During thermal 

disinfection the temperatures are stored at 10-second intervals 

for 20 minutes. The ECC function controller, which also serves 

as a power supply, can read these data and store them on an SD 

card module or it can serve directly as an interface to the PC or 

the computer-aided facility management system.

When fittings are connected to the ECC function controller via 

the system cable, this function controller takes over as a power 

supply and also provides data communication within the CAN 

island network. The multi-functional unit also offers the choice of 

an emergency power supply as well as programs for thermal 

disinfections, hygiene flushing, program-mode switching and 

shut-off for cleaning. 

Communication via Ethernet: 

The ECC function controller has an advanced Ethernet communication 

interface for connecting to a PC or a computer aided 

facility management (CAFM). As a data network technology for 

local data networks, Ethernet today represents the largest 

standardised communication platform worldwide. 

System connection for fittings: 

Two system cables can be connected to the ECC function 

controller for providing power and data communication, with a 

total length of up to 200 metres and a total number of 32 

fittings. 

Power supply function: 

The ECC has an integrated power supply unit providing 

24 V DC / 2.5 A. All fittings connected to the ECC function 

controller are powered via this supply unit. 

Emergency power supply: 

When a separate emergency power supply unit (lead gel 

accumulator with automatic charge control and an output of 

24 V DC / 3.2 Ah) is connected to the input provided on the 

ECC function controller, an uninterrupted power supply is 

assured in the event that the mains supply fails. 

Shut-down for cleaning: 

A contact input on the ECC function controller can be used to 

deactivate the fittings within an island group of fittings for the 

duration of a cleaning process. This deactivation will take place 

for a fixed period of time (automatic reactivation after a certain 

time) or when a contact pulse triggers reactivation, for example 

by means of a key switch. 

Switching program modes: 

An integrated contact input on the ECC function controller can 

be used to toggle between the program alternatives backed up 

on the fitting (e.g. day/night, school/after-school, paid/unpaid 

water delivery, classes/holidays, stadium/intermission, room 

occupied/vacant ...) e.g. via a timer and/or a key switch. Time 

and usage-dependent control functions can be called up with 

this facility. 

Hygiene flushes: 

The control programs for the 3 different types of hygiene flushes 

(fixed, dynamic and temperature controlled) are backed up in the 

electronic module and need to be activated via the system 

software. Additionally, the ECC function controller provides a 

fixed-value control program via which customised flushing can 

be performed. The function is triggered via a floating contact at 

the input of the ECC, e.g. via a separate switch. To prevent a 

high level of simultaneity, hygiene flushing for individual fittings 

is performed consecutively. 

Program processes in thermal disinfection (TD): 

The ECC function controller starts, controls and checks thermal 

disinfection processes in 7 phases: 

1. Start signal via external input contact or Ethernet 

network 

2. Heat up hot water tank in conjunction with electronic 

module for drinking-water heater 

3. Hot water enabled in conjunction with electronic 

module for circulation line 

4. Thermal treatment of circulation line 

5. Thermal treatment of fitting 

6. Cooling down phase 

7. System reset to normal operation 

Data storage via SD card module: 

An SD card module can be connected to the ECC function controller 

to save data externally. 

3 temperature memories (DW, HDW and TD), valve counters, 

operating hours, time lapsed since last hygiene flush or TD are 

saved in a csv file on the SD card of the card module.

The intelligent fitting technology and the open system structure of AQUA 3000 open 

facilitates customised water delivery functions and ready adaptation or expansion to accommodate 

facility-specific conditions. 

10

Levels of Communication 

The newly developed AQUA 3000 open system software makes it considerably easier 

to operate the system. Any number of electronic sanitary fittings can be centrally controlled 

and managed via a PC connected to the optionally installed network level. It is 

the first sanitary fittings system that facilitates worldwide open communication via a 

standard Ethernet connection (10/100 Mbit). With the AQUA 3000 open system it is 

possible to connect any sanitary room to an industry standard Ethernet system, thus 

facilitating access via the intranet or Internet. 

The system is controlled via the AQUA 3000 open system software. However, due to 

the open architecture of the programming and the Ethernet data structure, the water 

management system can also be connected to different systems within the 

computer aided facility management (CAFM) technology. The system adaptations that 

may be necessary for this must be provided by the client. 

The ECC function controller serves as the transfer point into the Ethernet. The corresponding 

island networks are controlled via CAN Bus technology. The serial CAN-Bus 

system (Controller Area Network) provides a speedy, reliable and cost-efficient system 

for networking fittings. The network incorporates several peer-to-peer control units 

(Bus participants) linked to each other to provide fast data transmission. 

The CAN-Bus system was developed in 1983 by Bosch and is designed to network 

control units in automobiles to reduce the amount of cables in cable harnesses and 

to minimise weight. CAN Bus systems are used particularly in safety-relevant environments, 

where a high level of data reliability is required (automation, medicine, 

aircraft technology).

With the help of the AQUA 3000 open system software, all sanitary engineering 

processes can be observed, controlled and recorded in a very user friendly manner. 

Furthermore, it is easy to set the parameters of system components. 

14

AQUA 3000 open system software 

The AQUA 3000 open system software facilitates fitting based parameter setting and 

status monitoring for all system components working in a group with an ECC 

function controller. These island networks are mapped out in fittings overviews. With 

its easy to use touch operation interface, the software offers a large number of control 

functions. 

Besides being able to set media-flow durations (water, soap, air, etc.) as well as 

communication parameters, it is possible to perform and record hygiene flushes and 

thermal disinfections. With the help of virtual island fittings (all fittings that are connected 

to an ECC function controller), which can be grouped, shifted and reassigned, 

the software uses a PC to map out the entire real-life sanitary system. Additionally, 

the AQUA 3000 open system software provides a large number of recording functions, 

such as recording and saving temperatures (hot and cold), usage and function statistics 

as well as event protocols (alarms).

Overviews of network and fittings 

Overview of fittings with program processes 

16 

The network overview shows all the ECC 

function controllers connected to the 

system. Within this overview it is possible 

to select an ECC island network and 

display it as a fittings overview. Within 

the fittings overview the user can read 

the operating status of every sanitary 

fitting, e.g. temperature, mode of 

operation as well as the condition of all 

connected sensors and actuators. At the 

fittings level it is also possible to 

configure thermal disinfection processes. 

An automatic overview is generated for 

each fitting; this overview displays all 

parameters that are necessary for 

operation. Thus the fittings function – e.g. 

shower with Piezo button – is shown with 

an easy to understand pictogram. 

Flow durations and sensor ranges 

can be set from here.

Basic settings for fittings 

Statistics function for fittings 

The individual basic settings can be used 

to set each fitting optimally for its specific 

application. Thus, for example, hygiene 

flushing can be configured in many 

different ways. Besides peak-load 

programs and shut-off for cleaning, it is 

also possible to set thermal disinfection 

parameters such as treatment time and 

treatment temperature for each individual 

fitting. 

The statistics display of each fitting 

shows all numerical values (e.g. number 

of times that a solenoid valve was 

triggered), operating hours, temperature 

changes as well as the time lapsed since 

the last hygiene flush. Also status 

information relating to the last thermal 

disinfection. When automatic long-term 

data saving is activated, for each day and 

each fitting the system displays a graphic 

showing the course of temperature and 

the frequency of usage across the entire 

day.

ApplicATions wiTh A sysTem 

Regardless of whether you are equipping a swimming pool or wellness facility, medical 

institution or office and administration building – AQUA 3000 open offers the economical 

and hygienic system solution for all types of buildings in public and commercial 

environments. 

18

Building-optimised planning and examples of installations 

In institutional applications, demands for economy, user convenience and hygiene for 

sanitary facilities are continually growing. Shower areas are increasingly the focal point 

of consideration with respect to possible sources of infection from the drinking-water 

system. Methods of thermal disinfection have emerged as being the recognised, 

state-of-the-art means of preventing such infection. In bus-networked fitting systems, 

hygiene requirements can be ideally complied with. 

AQUA 3000 open presents itself as a flexible sanitary system that is adapted to the 

individual needs of specific application conditions; its components can be set up from 

a building-block system. The type and structure of a building define the conditions of 

application and the type of usage. Application examples and system representations 

provide a basis for detailed embodiments and sample installations of AQUA 3000 open.

To perform a TD, a bypass solenoid valve 

cartridge is required in the function block 

of the respective fitting. Within a CAN 

island network with an ECC, the fittings 

that are to be given TD can be arranged in 


up to 8 groups that can be successively 

opened; this means, for example, that with 

smaller drinking-water heaters it is 

possible to simultaneously conduct 

thermal disinfection on 8 groups 

containing 4 fittings each. Parallel to the 

factory-programmed fittings functions, 

commissioning by the factory service team 

is also required for data communication 

and thermal disinfection.

While performing this method of thermal 

disinfection, high-temperature water is 

supplied to the hot and cold water inlet 

sides of the mixed water facility; this 

water then flows directly into the mixed 

water line to flush the fittings. Thermal 

disinfection is started via the ECC function 

controller, which controls the

The AQUA 3000 open system is based on the principle of a clear and simple system 

architecture. To accomplish this, only those components are used that are actually 

necessary for the specific application requirements. An optimised water management 

system can be accomplished with just a few system components. 

The main components of AQUA 3000 open are the fitting units; with their intelligent 

electronic modules these components can completely independently provide all the 

basic functions necessary for water control. A system is expanded to a network with 

the components of the system cable and its connections, an ECC function controller, 

and the operating software for controlling and monitoring the overall system. Additional 

system electronic modules for hygiene flushing and for incorporating drinking-water 

heaters for thermal disinfection supplement the system. 

From a concept to its realisation 

The basis for an optimum sanitary-room design is solid preliminary planning. This planning 

phase is oriented towards the actual conditions at the facility and the user- 

dependent requirements for the sanitary rooms. Qualified and proper consulting to 

comply with technical standards and requirements is the most important component 

for driving a conceptual idea to its final planning stage. We would be pleased to assist 

you in such planning and will pass on our know-how to you. We accompany you in all 

phases of planning implementation – even and particularly when dealing with complex 

system solutions.
