Z-Wave AeoTec Water Sensor 7 Pro User Guide

Instructions

This is a secure Alarm Sensor for Europe. To run this device please insert fresh 1 * 1/2 AA batteries. Please make sure the internal battery is fully charged. 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 Smart Start. Please scan the QR code inside the battery compartment of the device and your controller will add the device automatically when powered up.

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 ZWave 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.

For more information about Z-Wave technology, devices, white papers etc. please refer to www.z-wave.info.

Product Description

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

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 tamper switch is tripped, push the tamper for 5 seconds until the red LED blinks. Then release tamper and push it again for 5 seconds until LED blinks.

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.

After the main sensor is mounted, the water sensor probe must be connected to the screw 3pin terminal inside the main sensor. After the sensor probe is connected it must be put on the floor or onto any other surface, where water leakage must be detected.

Inclusion

Tripple click the tamper switch

Exclusion

Tripple click the tamper switch

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 device using the association group 2. The device is protected by a tamper switch.

The device contains three sensors with the following accuracy measures:

Humidity: +/- 3 % on relative humidity, +/-1 % hysteresis
Temperature: 0 … 65 grd C +/- 1 Kelvin
Dew Point: 0 … 65 grd C +/- 1 Kelvin (calculated from other sensor values)

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.

Screw Terminal
The product supports the connection of the water sensor probe via 3-pin screw terminals with the following pinout:

#1: VCC (direct battery supply)
#2: Digital Input
#3: Ground

VCC + Ground terminals can be used to externally power the sensor. Digital + Ground is used to connect the water sensor probe.

Link testing

When activated by configuration parameter #4 the device can perform a link test with device No.1. Doubleclicking the tamper will start the process. As a result, the red LED will blink one time in case of success and 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)

Quick trouble shooting

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

Make sure a device is in factory reset state before including. In doubt exclude before include.
If inclusion still fails, check if both devices use the same frequency.
Remove all dead devices from associations. Otherwise you will see server delays.
Never use sleeping battery devices without a central controller.
Dont poll FLIRS devices.
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. The 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 devices that will receive controlling commands. These lists are called association groups and they are always related to certain events (e.g. button pressed, sensor triggers, …). In case the event happens all devices stored in the respective association group will receive the same wireless command wireless command, typically a ‘Basic Set’ Command.

Association Groups

Group Number	M aximum Nodes	Description
1	5	Lifeline
2	5	Control devices when water leakage is detected
3	5	Sends out alarm message when water leakage is detected
4	5	Sends alarm messages when tamper is tripped

Configuration Parameters

Z-Wave products are supposed to work out of the box after inclusion, however certain configuration can adapt the function better to user needs or unlock further enhanced features.

IMPORTANT: Controllers may only allow configuring signed values. In order to set values in the range 128 … 255 the value sent in the application shall be the desired value minus 256. For example: To set a parameter to 200 it may be needed to set a value of 200 minus 256 = minus 56. In case of a two byte value the same logic applies: Values greater than 32768 may needed to be given as negative values too.

Parameter 3: Visual LED Indications

This parameter defines when the red LED will indicate events. Disabling all indications may extend battery life.
