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 temperature-
controlled 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 circum-
stances
▪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.

2.3.1 CAN bus cable
Bus cables for the wiring of CAN bus systems (controller area network) in accordance with
ISO 11898 must be used for bus systems with 120 Ω nominal impedance. Only when such
cables are used can a high level of data transfer security be guaranteed.

The 120 Ω terminal resistor may only be installed in the last control component of a CAN bus
cable. The MASTER does not require a terminal resistor.

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.

See Miscellaneous settings
Check to see if the antenna icon can always be
seen and if the LEDs light up green on all KHS

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.
