Operating modes
Smart water valve
VA4200WZ / VA4201WZ

Selection of operating mode
The smart water valve offers three operating modes:
Option 1 – Wi-Fi Leak Supervisor Mode
Option 2 – Remote Controllable Valve Mode
Option 3 – Zigbee Network Mode
Option 1 - Wi-Fi Leak Supervisor Mode
In « Leak Supervisor » mode, the leak detectors (not included) send a closing signal to the valve to automatically shut off the main water supply as soon as a leak is detected.
A notification will be sent by email or SMS advising of the source of the leak and the valve closure.
To configure your valve in «Wi-Fi Leak Supervisor» mode, you must:
Remove the valve cover by unscrewing the 4 screws with a flat screwdriver.
Make sure that the mode switch is set to « 1 ».
Connect the valve to an electrical outlet, using the supplied adapter, near where it will be installed. By doing so, you will validate the range of the Wi-Fi communication between the valve and your network.
Open the app and log into your Sinopé Water Leak Protection account or create an account.
If you already have a Neviweb account, use the same login information to configure and control the valve.
In the menu on the right, choose « Add a device » and follow the steps specified by the app.
Connect your Sinopé smart water leak detectors by referring to the Sinopé water leak detector installation guide.
Option 2 - Remote Controllable Valve Mode (without smart water leak detectors)
The « remote controllable valve » mode allows controlling the valve’s opening and closing remotely via the local Wi-Fi network. To use this mode, you must first download the Sinopé Water Leak Protection app and follow the instructions to add the device to the application.
Note: Mode 2 does not supervise water leaks.
Option 3 - Zigbee Network Mode
The « Zigbee network » mode allows you to remotely control the opening and closing of the valve through your Zigbee compatible gateway.
To configure your valve in « Zigbee Network » mode, you must:
To connect the valve to your Zigbee compatible system, refer to its instruction manual.
Set the mode switch to « 3 ».
Connect the valve to an electrical outlet, using the supplied adapter, near where it will be installed. By doing so, you will validate the range of the Zigbee communication between the valve and your network.
Press the « A » button to associate the valve with the Zigbee network.
