INFORMATION

For installation, maintenance and operation

Installation and operation

Read the manual and follow the instructions
before installation!
Installation and maintenance must be carried
out by qualified plumbers.

Provide the manual to the plant operator and
keep on hand for further reference!

Make sure that the installation location is
frost-proof and not prone to flooding.

Priority must be given to the national
standards and provisions on sanitary
installations and accident prevention.

Warranty

No warranty in case of:

- Non-compliance with the manual.

- Damage due to incorrect installation.

- Unauthorised modification of the product.

Use

Thanks to the MASTER/SLAVE technology,
KHS Mini Control System can be used to
implement specific water exchanging
measures to maintain drinking water
hygiene. For each individual water

exchange group, time or temperature­controlled water exchange can be
configured individually or according to a
specified water volume.

Only skilled professional personnel are
permitted to operate electrical systems in
accordance with DIN EN 50110-1.

Do not use the device for other purposes
than described above in non-freezing
interiors. Any other uses constitute misuse.

Warnings used in the manual:

Warning!

Highlights risks that may result
in injury, material damage or
contamination of drinking
water.

Note!
Highlights risks that may result
in damage to the plant or
dysfunction.

▪ The reliability of the supplied unit is

only ensured when used as intended.
Never exceed the limits stated in this
documentation under any circum­stances

▪ During assembly and maintenance,

make sure that the control is not
switched on.

▪ Use only original/approved spare parts

 otherwise no warranty claims will be

recognized.

▪ Be sure to comply to local regulations

on waste recycling and disposal.

Installation

Allow only certified electricians to assemble and install electrical equipment.
Danger of fatal electric shock.

Rigid leads must form a loop for wiring so that there is no pressure on the
terminals and the housing closes without resistance.

Commissioning

Before commissioning, make sure the
connections have been made properly and
professionally and that the system is
properly protected. The pertinent
regulations (EN, VDE, etc.) and the

regulations of the local energy utility must
be complied with. After finishing the wall
installation and the electrical installation,
apply the mains voltage of 230V.

Allow only certified electricians to assemble and install electrical equipment.
Danger of fatal electric shock.

To simplify configuration and to guarantee correct installation, fill in the
system commissioning overview of the KHS Mini Control System (see supply
pressure, Chapter 10.2) before making the settings.

It is mandatory to fill in the form to be able to take advantage of the
optional factory support.

All menus have a "rolling" structure, i.e.,
pressing the "↓ key" on the last menu item

jumps back to the first menu item.

connection been established.

When using A/B valve technology, always make sure that the B valve is
configured first. A valves can then be assigned to the B valve. The assignment
of the A valves is shown in the following. For information on valve technology,
please see Chapter 10.1.

3.1.2.4 Operating modes

In the "Operating modes" submenu, programs and times are added to the actuators and
sensors.

Mode

Description

Time Control

Triggers a water exchange of defined duration at a certain
point in time.

Temperature control

Triggers a water exchange when a predefined start
temperature is reached, until a predefined stop temperature
is reached.

Volume control

Triggers a water exchange with a defined flush volume at a
certain point in time.

Backup

Backs up a distribution line by means of a water sensor in a
predefined time window.

Datalogging

Acquires sensor values in a predefined time window with a
predefined sampling rate.

Routine

Triggers a water exchange for a predefined duration or
quantity if a temperature control has not actuated for a
certain time.

If two or more valves are simultaneously opened in a drinking water
system, under certain circumstances pressure fluctuations or a large
pressure drop can occur in the system. For that reason, make sure
beforehand that the required flow pressure is continuously guaranteed at
all tapping points. You are recommended not to perform simultaneous
water exchanging measures.

If the program switch is "Activated" (see Chapter

3.1.2.6), a query is presented during the operating
modes configuration to determine the program this
applies to (see right). The two mentioned flushing
programs can be switched using an external
manual switch. The electrical connection is shown
in Chapter 2.2.
