Aeotec Water Sensor 7 Pro (ZWA019) — User Manual

User guide for the Aeotec Water Sensor 7 Pro (model ZWA019) — a Z-Wave battery-powered leak/flood detection sensor with SmartStart pairing support.

Overview

Water Sensor 7 Pro is intended for use in dry locations that may become wet — it detects water and leaks via a probe with two contacts. Only when both probe contacts come into contact with a liquid does the sensor send a leak alert to your Z-Wave gateway. It contains small parts and should be kept away from children.

What's Included

• Main base unit
• Probe
• Main front enclosure
• Double-sided tape for main base unit (x2)
• Screws (x4)
• Double-sided tape for sensor head (x2)

Optimal Placement

The main unit should be placed in a dry location, mounted vertically on a wall above the area you wish to monitor for potential floods or leaks. It is the sensor probe that detects liquids, so it must be positioned where any leak or water flow will come into contact with it — consider which direction a flood or leak may travel and where one is likely to occur. Ensure both probe contacts can detect any leak or flood.

Quick Start — Installation & Pairing

1. Press and hold the Latch on the larger sensor part, separate the front from the back-mount plate, and pull the case off completely.
2. Remove the Pull Tab to engage the sensor's pre-installed batteries. The LED will flash red, indicating it is powered on.
3. Add Water Sensor 7 Pro to your Z-Wave network:
   • If your gateway supports SmartStart: scan the QR code on Water Sensor 7 Pro using the gateway's app — the sensor joins automatically.
   • If your gateway does not support SmartStart:
     1. Set your Z-Wave gateway into "add device" mode (refer to your gateway's manual if unsure).
     2. Press the sensor's Tamper Switch 3 times within 1.5 seconds — located on the lower right side with the battery pointed forward.
     3. The sensor joins your Z-Wave network; its LED will blink green and red, then join the network.
     4. If pairing is successful, the LED changes to green for 3 seconds before turning off. If pairing fails, the LED flashes red 3 times — repeat the step or contact Aeotec support.
4. After testing Water Sensor 7 Pro in your chosen installation location, affix the main sensor's back-mount plate using the provided screws or double-sided tape. Important: make sure the sensor is completely enclosed over the mounting plate, otherwise the battery will drain within a few days from remaining fully active.

Notes

• QR code is used for SmartStart inclusion; the DSK code is found on the packaging — do not remove or damage either.
• Once paired, Water Sensor 7 Pro becomes part of your Z-Wave home control system — configure it and its automations via your Z-Wave software's interface or user guide.
