4.4 Function
The MultiSafe Leak Detector Control Valve is an efficient leakage protection system
according to DIN 3553. Thanks to continuous monitoring, any leak is detected at an early
stage and the risk of extensive water damage is reduced because the water supply is cut
off automatically.
The MultiSafe Leak Detector Control Valve features an electronic water metering device
(by means of a turbine), an electrically-driven shut-off valve, a pressure sensor to
monitor the smallest leakage volumes and a multifunctional display. In addition,
the device determines water hardness and indicates it in three stages.
The MultiSafe Leak Detector Control Valve can connect to the Reliance Valves App
via its access point. Provided there is an active internet connection, the MultiSafe
transmits the measured values from the drinking water installation, e.g. volume flow,
flow rate per time, duration of volume flow, pressure drop and temperature via
a secure connection.
Even if the Internet connection is down, the parameters will continue to be monitored.
However, during this period, there is no communication with the server and no
notification in case of deviations from set parameters. Of course, the system can
also operate without Internet connection.
The mains adapter is used for power supply. The scope of delivery includes a battery
for short-term protection in case of power failure.

Explanation and setting options Ex works
Flow-based
leakage
If the MultiSafe detects unusual flow rates within short
periods of time, the device will consider this as leakage.
Flow-based leakage can be set up to a volume of 5,000 l/h,
yet this setting can also be switched off completely.
Example:
The ex works setting of a maximum flow of 3,000 l/h
continues for at least one minute — mostly in case of pipe
bursts: the MultiSafe Leak Detector Control Valve will
immediately isolate the pipe system.
Install an additional radio-controlled MultiSafe Floor Leak
Sensor in critical places. This will determine local water
leaks, regardless of the selected settings. MultiSafe Floor
Leak Sensor can be connected to the MultiSafe so that the
latter can immediately isolate the system.
3,000 l/h
Return to
“present”
mode
The user can determine the time when a selected prole
shall be active. Once the set time is over, the MultiSafe will
return to the “present” mode. The options for the settings
range between one hour and 28 days. Times will be given
in hours.
Example:
You will be away from home for four days and therefore
you select a mode with low water consumption. If you select
your return time to “present” to be four days, the MultiSafe
will automatically switch back to this mode after the
selected time.

Micro-
leakage test
The device will check at regular intervals for the smallest of
leaks. The microleakage test can be switched on or off.

Warning
sound
The warning sound can be switched on or off. On
Self-
learning
phase
During the self-learning phase, the MultiSafe Leak Detector
Control Valve analyses water consumption and the usual
household usage. The measured values can then be used for
your own, selected prole. The duration of the self-learning
phase can range between one and 28 days.

Reliance Valves App Settings range
Please find below the most important terms for the settings range of the MultiSafe Leak
Detector Control Valve in the Reliance Valves App. Examples are given for illustration.
Explanation and setting options Ex works
User profile Individual setting of the device, adjusted to the user prole.
A maximum of eight user proles are possible.
Example:
Usually, the two teenagers are present at weekends.
The two teens like to take long showers. To make sure
that the parents have sufficient water, too, they create a
new profile with the corresponding parameters.
Refer to the smart self-learning phase of the MultiSafe to
determine the optimum safety levels for your new profile
Present
(ac tive)
Absent
Volume-
based
leakage
Maximum amount of water drawn after opening a draw-off
point. The setting for volume-based leakage ranges from 10
to 9,000 litres. Volume-based leakage may be switched off.
Example:
The draw-off point with the highest draw-off amount is a
bathtub with a capacity of approximately 120 litres. Set the
value of leakage in the presence-mode to 200 litres so that
the bathtub can be filled up without any problem and you
can still draw water.
300 l
Time-based
leakage
If a draw-off is registered that takes longer than the time
set for a specic volume, the device will isolate the system.
Time-based leakage can be set to 30 minute intervals,
ranging between 0.5 and 25 hours. This setting can also
be switched off.
Example:
In addition to the amount of water set for volume-based
leakage, a period of time can be determined when water
may be drawn without interruption. If, for example, the time-
based leakage is set to 60 minutes, the MultiSafe will isolate
the system once this time has elapsed, even if the set
volume has not yet been reached.
