CubicSecure
LTCS01
Intelligent water shut-off device
CubicSecure is a water fault switch that protects against leaks by continuously
measuring water consumption, water pressure and temperature. The device
alarms for both micro-leakages and larger leaks. When the device detects a leak,
it automatically shuts off the water flow. The device can be installed in villas,
terraced houses and apartments

Thank you for choosing the CubicSecure
CubicSecure measures your water flow in real time and detects water leaks immediately. The
CubicSecure protects your home from damage caused by micro-leaks and broken water pipes. The
compact design makes CubicSecure easy to install and fits in water cabinets.
CubicSecure works completely on its own and does not need any connection to the internet. If, on
the other hand, you want to receive notifications about alarms and the opportunity to see your
individual water consumption, the product needs to be connected to Wi-Fi. When the device is
connected, you can control CubicSecure remotely through our app.
CubicSecure is developed and manufactured in Sweden with advanced technology for water
measurement.
INSTALLATION INFORMATION
CubicSecure is a small device that is easy to
install in tight spaces. The device is easily
mounted on main incoming water pipes in a
villa or apartment. The device is equipped
with a knob for manual ball-valve override in
the event of a power failure or emergency.
PACKAGE CONTENTS
●1x CubicSecure device
●1x Mains adapter
●2x Plane Adapter (LK RSK-1870678)

MOUNTING INFORMATION
The CubicSecure must be installed by a
plumber according to the Safe Water
Installation industry regulations.
Security systems such as residential sprinklers
and emergency cooling of solid fuel boilers or
similar must be connected before the device. If
they are installed afterwards, they risk running
out of water supply.
Install the device after supplying security
systems that require water.
Water filters that are backwashed should be
connected first so that their function is not
disturbed. The system prevents water damage
that may occur after the location of the device.
When installing metal pipes in the distributor
cabinet, the pipe must be provided with an
electrical protective equalization (earthing) which
must be installed by a qualified electrician if
there is not already an earth screw in the
cabinet.
To avoid scalding in apartments, two
CubicSecures can be paired. Pairing provides a
synchronized automatic shut-off between the
hot and cold water lines.
MOUNTING STEPS
1. Install the device on the incoming
water line directly after the water
meter’s shut-off valve and any
non-return valve.
2. Tighten connections without
damaging the plastic casing of the
device.
Correct installation of the device. The arrows
show the direction of water flow.
TIP! The device is equipped with a counterhold
on the underside. Use an adjustable wrench on
the counterhold. It is also possible to use a
screwdriver in the slot to create a counterhold.

SETUP
1. Connect power to the device using
the micro-USB power adapter
included.
2. Check that the STATUS LED is WHITE.
White light indicates that the device is
working normally. If no LEDs are lit,
check that the wall socket or power
adapter is functional.
Wi-Fi SETUP
To be able to follow the device's
measurements and alarms remotely
via a smartphone, an app and a
connection to a Wi-Fi network are
required.
Download and install the Quandify
app from App Store or Google Play
Store and follow the instructions.
HOT/COLD WATER PAIRING
1. Install and start the CubicSecures.
One for hot water and one for cold
water.
2. Hold down the CONNECT button for 5
seconds on the device installed for
cold water. The CONNECT LED starts
flashing YELLOW and BLUE.
3. Hold down the CONNECT button for 5
seconds on the device installed for
hot water. The CONNECT LED starts
flashing YELLOW and RED. You can
also press once on CONNECT to
switch the hot/cold water designation.
4. Make sure that the CONNECT LEDs on
both devices flash GREEN rapidly for
about a second.
If pairing was not completed, redo process
steps 2 to 4. To delete a pairing, perform a
factory reset.

DESCRIPTION
Micro leakage
> 0.01
Detected by the valve being automatically closed daily to measure a
pressure drop above 0.5 bar for a maximum of 45 seconds.
Medium
leakage
> 6
The device alarms and shuts off the water after a continuous flow for
at least 45 minutes.
Large leakage
> 1500
The device alarms and closes the valve after a continuous flow over
1500 l/h for at least 90 seconds.
Note that a larger leakage alarm will always override a smaller leakage detection. Above thresholds can
be modified using the mobile application.

FUNCTION CHECK
WATER SHUT-OFF CHECK
1. Press the WATER ON/OFF button. The
LED turns off when the ball valve has
completely shut off the water flow.
2. Open a tap. Check that no water
comes out of the tap.
3. Press the WATER ON/OFF button. The
LED shines white when the valve is
fully open. Check that water is now
coming out of the open tap. During
active waterflow the LED flashes
white.
The picture on the left shows an open valve, a closed
valve is shown on the right.
MICRO-LEAKAGE DETECTION CHECK
1. Open a tap to simulate a very small
leak. A dripping stream of water will
suffice.
2. Press the WATER ON/OFF button to
close the valve.
When the valve is closed, the STATUS LED will
flash GREEN while the pressure sensor scans
for small leaks for about 45 seconds.
If the pressure sensor manages to find a leak,
the STATUS LED starts flashing YELLOW. If the
pressure sensor does not find a leak, redo the
steps with a slightly larger leak.
3. Close the tap and press the WATER
ON/ OFF button to open the valve
again.
LEAKAGE DETECTION CHECK
1. Open a tap with the valve in the open
position.
2. Leave the valve at full flow on the tap
for at least 45 minutes.
3. Check that the device emits an alarm
and switches off the flow after 45
minutes.
4. Then close the tap and reset the
device.

ACKNOWLEDGE ALARMS
●Press the WATER ON/OFF button
once to acknowledge and turn off the
alarm.
●Press the WATER ON/OFF button
again to open the valve.
Note that an acknowledgment resets all ongoing leak
detections.
DISABLE LEAKAGE
DETECTION
The leakage detection can be deactivated if a
larger amount of water is needed to e.g. fill a
pool or for irrigation. The preset time is 24
hours.
The deactivation of the alarm can be done in
the app or manually by holding down the
WATER ON/OFF button for 5 seconds. The
LED will turn yellow when deactivated.
RESET Wi-Fi
If the CONNECT LED is red or dark:
●Press the CONNECT button once.
If the CONNECT LED is white:
●Restart the device using the power
cable and press the CONNECT button
once the CONNECT LED is red. This
can also be done via the app.
FACTORY RESET
1. Firstly, insert a paperclip into the hole
on the reset button while plugging in
the power cable for 3 seconds.
2. Wait for about three minutes. After
about three minutes, the device has
reset and the LEDs light up again.
Note that you will lose applied firmware updates and
hot/cold pairings when doing a factory reset.
OPERATION
You can access the device data such as water
usage, temperature, pressure, valve position
and leakage status via the mobile app. When
the device is powered on, it performs daily
automatic leakage tests and exercises the
ball-valve.
After a potential power failure, the device
returns to the same mode it was in before the
power failure.
SERIAL NUMBER
You can find the 12 characters long serial
number on the bottom of the CubicSecure.
The data-matrix beside the serial number can
also be used using barcode scanners.
