Area of application
The KEMPER KHS Mini System Control can be used for monitoring and water exchange in drinking
water systems. The water exchanges can be generated and documented as flushing logs with the
MASTER 2.0 control. The dedicated water exchanges prevent stagnation in the drinking water with the
aim of maintaining the drinking water hygiene in the drinking water systems. Based on the KHS Mini
System Control MASTER, the MASTER 2.0 is a web-based further development that no longer
requires configuration and readout software. The system works entirely independent of the operating
system. On top of that, some new functions have been added that make the device also interesting for
large buildings.
NOTICE:
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. It is recommended to
not make simultaneous water exchanges.

KHS MASTER/SLAVE technology
The MASTER/SLAVE technology can be used to trigger flushing measures for maintaining the
drinking water hygiene for the drinking water system. The corresponding operating modes can be
individually configured for each individual water-exchange group. Positioning the individual MASTER
or SLAVE controls directly on the water exchange groups ensures short wiring distances for
interconnection.

Shown in Ill. 2.1 as an example is a KHS Mini
System Control -SLAVE- (2) in connection with a
water exchange group which comprises a KHS-
VAV Maximum flow isolating ball valves (4),
Temperature sensor (1), Volume flow sensor (3)
and a KHS Drain (5). The components of the water
exchange group are only listed as examples here.
The operating mode depends on the components
and the valve technology (for valve technology
please refer to Chapter 13.1). In the example
illustrated, the -SLAVE-(2) controls the specified
water exchange groups. It is connected with the
MASTER 2.0- through a CAN bus cable.
