Important safety information

Please read this manual carefully. Failure to follow the recommendations in this manual may be dangerous or
may violate the law. The manufacturer, importer, distributor and seller shall not be liable for any loss or damage
resulting from failure to comply with the instructions in this manual or any other material. Use this equipment
only for its intended purpose. Follow the disposal instructions. Do not dispose of electronic equipment or
batteries in a fire or near open heat sources.

What is Z-Wave?

Z-Wave is the international wireless protocol for communication in the Smart Home. This device is suited for
use in the region mentioned in the Quickstart section.

Z-Wave ensures a reliable communication by reconfirming
every message (two-way communication) and every mains
powered node can act as a repeater for other nodes (meshed
network) in case the receiver is not in direct wireless range of
the transmitter.

This device and every other certified Z-Wave device can
be used together with any other certified Z-Wave device
regardless of brand and origin as long as both are suited for
the same frequency range.

If a device supports secure communication it will communicate with other devices secure as long as this
device provides the same or a higher level of security. Otherwise it will automatically turn into a lower level of
security to maintain backward compatibility.

SmartStart. Available in selected Z-Wave Plus devices built upon 500 series technology and all devices built
upon 700 series technology, SmartStart lets you setup Z-Wave devices in seconds.Using SmartStart enabled
apps, simply scan the QR code on any compatible app to connect it to your Z-Wave gateway.

Product Description

The AEOTEC Water Sensor 7 Pro is a sensor, which detects water leakage, measures temperature and
humidity. The sensor is easily retrofittable.

Thanks to its slim design the AEOTEC Water Sensor 7 Pro can be installed in any bathroom, behind a kitchen
sink or in any other tight space. The sensor just has to be installed on the wall and the sensor probe must be
put on the floor.

By using the internal temperature and humidity sensor, the device will report on any significant change.
Tripple clicking the tamper button includes (adds) and excludes (removes) the device. A single click on the

button will wake up the device. The device supports the Z-Wave Security S2 framework with authenticated and
unauthenticated network keys. Please follow the instructions on the central controller when including. The
device also supports SmartStart.

Prepare for Installation / Reset

Please read the user manual before installing the product.
In order to include (add) a Z-Wave device to a network it must be in factory default state. Please make sure

to reset the device into factory default. You can do this by performing an Exclusion operation as described
below in the manual. Every Z-Wave controller is able to perform this operation however it is recommended to
use the primary controller of the previous network to make sure the very device is excluded properly from this
network.

Reset to factory default

This device also allows to be reset without any involvement of a Z-Wave controller. This procedure should only
be used when the primary controller is inoperable.

Once Cover is removed and the tamper switch is tripped, push the tamper for 5 seconds until the RED LED
blinks once. Then release tamper and push it again for 5 seconds while the RED LED is blinking until the
GREEN LED blinks once.

Safety Warning for Batteries

The product contains batteries. Please remove the batteries when the device is not used. Do not mix batteries
of different charging level or different brands.

Installation

The sensor can be mounted on the wall. Mounting can be accomplished either using the tape by peeling off the
protection foil or using two screws with the holes inside the battery compartment.
Water Sensor probe which is hardwired to the Main Unit must be put on the floor or onto any other surface,
where water leakage must be detected.

Inclusion/Exclusion

On factory default the device does not belong to any Z-Wave network. The device needs to be added to an
existing wireless network to communicate with the devices of this network. This process is called Inclusion.

Devices can also be removed from a network. This process is called Exclusion. Both processes are initiated
by the primary controller of the Z-Wave network. This controller is turned into exclusion respective inclusion
mode. Inclusion and Exclusion is then performed doing a special manual action right on the device.

Inclusion (If your gateway does not support SmartStart)

1. Open the housing.

2. Remove the battery protection.

3. Press the tamper on the side of the appliance three times quickly.

Exclusion

1. Open the housing.

2. Press the tamper on the side of the appliance three times quickly.

Product Usage

Once installed the sensor will report Leakage Detected and No Leakage status changes to a central Z-Wave
controller using notification commands. Additionally, the sensor can directly control other devices using the
association group 2. The device is protected by a tamper switch.

The device contains two sensors with the following accuracy measures:

• Humidity: ± 3% RH (max), 0–80% RH

• Temperature: ±0.4 °C (max), –10 to 85 °C

Water leakage detection
The water leakage detection allows reporting as soon as water hits the sensor probe. This is accomplished

using the command class notification - water alarm - water leakage detected unknown location. After the
leakage has stopped (the sensor probes are not short-connected through the water) the device reports this to
the central controller.

Link testing
When activated by configuration parameter #4 the device can perform a link test with device No.1. Double-

clicking the tamper will start the process. As a result, the GREEN LED will blink one time in case of success
and RED LED will blink three times in case of failure.

The device sends the following notifications to the central controller:

• Water Leakage Unknown Location (0x05 - 0x02)

• Tamper Removed (0x07 - 0x03)

• Replace Battery Now (0x08 - 0x0b)

Node Information Frame

The Node Information Frame (NIF) is the business card of a Z-Wave device. It contains information about the
device type and the technical capabilities. The inclusion and exclusion of the device is confirmed by sending
out a Node Information Frame. Beside this it may be needed for certain network operations to send out a Node
Information Frame. To issue a NIF execute the following action: Press the tamper once

Quick trouble shooting

Here are a few hints for network installation if things dont work as expected.

1. Make sure a device is in factory reset state before including. In doubt exclude before include.

2. If inclusion still fails, check if both devices use the same frequency.

3. Remove all dead devices from associations. Otherwise you will see severe delays.

4. Never use sleeping battery devices without a central controller.

5. Dont poll FLIRS devices.

6. Make sure to have enough mains powered device to benefit from the meshing

Firmware-Update over the Air

This device is capable of receiving a new firmware 'over the air'. The update function needs to be supported by
the central controller. Once the controller starts the update process, perform the following action to confirm the
firmware update: Wake Up the device by removing the cover. Then hit the tamper switch once.

Association - one device controls an other device

Z-Wave devices control other Z-Wave devices. The relationship between one device controlling another device
is called association. In order to control a different device, the controlling device needs to maintain a list of
