Quick Start
Installation of Water Sensor 7 Pro.
Open the cover by pressing the clip on the side and pulling the cover upwards.
Insert a fresh 1 * 1/2 AA battery, but pay attention to the polarity
Install your Water Sensor 7 Pro.
The Water Sensor 7 should be placed wherever you want to monitor for possible flooding or leaks. When placing the
Water Sensor 7, consider the direction in which a flood or leak may flow and where it may occur. The contacts of the
Water Sensor 7 probe will detect the liquid, so the probe must be placed so that any flood or leak will come into contact
with it. When the probe contacts come into contact with a liquid, the Water Sensor 7 sends a leak warning to your Z-
Wave Gateway. Make sure that both contacts are capable of detecting leaks or flooding.
Adding your Water Sensor 7 to Z-Wave network.

Communication test.
This utilizes the Power Level command class to determine the health between the Water Sensor 7 and your Z-Wave
gateway. This will tell you if the Water Sensor 7 has a healthy connection to your system and is a great method of
debugging connectivity issues.
1. Set Parameter #4 to value #1
2. Double click the Tamper Switch.
3. Result:
Green LED blinks once - success
Red LED blinks 3x times - failure
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:
1. Wake Up the device by removing the cover.
2. Hit the tamper switch once.
Send a wake-up notification.
In order to send your sensors new configuration commands from your Z-Wave controller or gateway, it will need to be
woken up.
1. Wake Up the device by removing the cover.
2. Hit the tamper switch once.

Note:Water Sensor 7 remains awake until the housing is closed again.
Remove your Water Sensor 7 from Z-Wave network.
Your sensor can be removed from your Z-Wave network at any time. You'll need to use your Z-Wave network's main
controller/gateway. To do this, please refer to the part of your gateways respective manual that tells you how to remove
devices from your network.
1. Set your Z-Wave controller into unpair mode.
2. Triple-click the tamper switch on Water Sensor 7 within 1.5 seconds - this will cause the LED to blink five times.
3. After a successful exclusion, it will light up its LED for 2 seconds then deactivate.
Reset your Water Sensor 7.
This device also allows being reset without any involvement of a Z-Wave controller. This procedure should only be used
when the primary controller is inoperable.
To manually factory reset:
1. Remove the cover of Water Sensor 7
2. Press and hold tamper switch for 5 seconds until the red LED blinks.
3. Release the tamper switch
4. Immediately press and hold the tamper switch for 5 seconds until the red LED blinks.
Association Groups
Group Association allows Water Sensor to directly communicate with other Z-Wave devices directly without the need for
the Z-Wave Controller to act as an in-between controller. This using this function will help with communication efficiency
and limit the amount of time it takes to control a device.
Group
Number
Maximum
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
