OWNER’S MANUAL / INSTALLATION GUIDE
Introduction
WV-01 is a patented, wireless, water detection and automatic water shut-off system that works as an automatic
valve for a home’s main water supply line and can be easily installed by a certified professional plumber.
WV-01 is a new professional grade, electrically operated water shut-off valve introduced by FortrezZ LLC.
Every year nearly 1 million families have their homes ruined and their lives overturned by water damage and the
subsequent repairs. The WV-01 used in a Z-Wave home automation network along with Z-Wave water alarm
sensors (WWA-0X), helps to reduce or eliminate water damage caused by leaky pipes or faulty appliances.
WV-01 can also work as a Water Level / Irrigation device. It can be set up to be on a ‘timed’ schedule using a
Smart Controller inside a Z-Wave home automation network.
WV-01 operates in a Z-Wave enabled home network which uses the latest and most successful wireless home
automation technology to provide protection 24/7, 365 days a year.
System Components
The Emergency Water Shut-off Valve System has two basic components:
1. A motorized ball valve and housing containing a wireless Z-Wave radio transceiver which automatically
turns off your water supply when any wireless water alarm sensor detects water or low, potentially
freezing temperature.
2. One or more wireless water alarm sensors (WWA-0X), which detect water from a leak or overflow, or
detect potentially freezing temperatures, and cause a wireless Z-Wave signal to be sent to the WV-01 to
turn off the water supply.

Three panel-mount tactile switches to manually activate / program the valve.
A Z-Wave system, which includes the WV-01 in combination with sensors and Z-Wave Gateway Controller
(available in kits or separately), can automatically send you an email, text message, or phone call (based on your
controller configuration) when a water leakage or overflow event occurs.
A Z-Wave system which can be remotely operated (via internet or phone) through a Z-Wave Gateway Controller.
When installed properly in a Z-Wave network, the WV-01 and its system of WWA-0x sensors constantly monitor
the home for water leakage. The WWA-0x sensors are battery operated, wireless water / moisture / temperature
sensors which are strategically placed throughout the home. If one of these sensors trip, a wireless Z-Wave radio
signal is relayed through the Z-Wave home network causing the WV-01 to turn off the household water supply.
The Z-Wave system can also include many other devices from other companies that are Z-Wave certified such as
light switches, thermostats, scene controllers, and other useful Z-Wave devices.
General Safety Information
Adherence to all local and municipal building, plumbing and electrical codes as they pertain to the
installation of the Water Valve WV-01 System is of utmost importance. Codes in some areas may
require that a licensed plumber be employed to do the installation, or that the proper permits be
obtained prior to any installation. Even if local codes do not require a licensed plumber to do the
installation, it is necessary that the installer has a professional level of competence in both plumbing
and electrical skills to perform the installation. These instructions assume this level of knowledge and
skill. If in doubt, use a licensed professional.
Disconnect power source before working on or servicing the unit. Failure to do so could result in
serious personal injury.
It is strongly recommended that eye protection be worn while servicing the system. Failure to do so
could result in personal injury.
CAUTION: If the ball valve is not yet installed in a water line, ALWAYS KEEP FINGERS AND
FOREIGN OBJECTS AWAY FROM THE BALL VALVE. Objects in the path of the closing valve
can damage the ball valve and the ball valve can cause serious personal injury.
Pre-installation Testing of Water Valve WV-01
Although each unit is pre-tested at the factory, it is recommended that the unit be tested prior to installation to
ensure proper operation in your home. Operating the valve before connecting to the water line will not damage it.
Use caution!
• The valve closes with enough force to cut off a finger.
• Be extremely careful to ALWAYS keep fingers and other items out of the valve.

Manually Test the Valve
Check the position of the valve by looking in either threaded end. In the open position, you will be able to see
through the valve; in the closed position only the shiny surface of the ball will be visible. Place the base of the
housing on a sturdy surface, as close as feasibly possible to the location where it will be permanently installed.
Plug the Water Valve WV-01 power adapter cord into a nearby 110V AC outlet.
Use Caution! The valve may open or close automatically as soon as it is plugged in!
The open or closed indicators should show the status as appropriate. Within 10 seconds, the status
indicator light will start blinking. Grasp both sides of the housing (not the valve) with the valve pointing away from
you for safety. Being very careful not to have your fingers or other objects near the valve openings, press the
colored circle just below the unlit indicator light of the opposite valve position. You will hear the motor change the
valve position. Again, look into the threaded end of the valve to verify that the valve has changed position. If it
appears that the valve has not turned from one position to the other, DO NOT try to reposition the valve
yourself by inserting any tool or fingers into the valve. Operate the valve several more times from open to
close, checking each time for proper positioning. If you are experiencing trouble getting the valve to open and
shut, call the installation help line listed on the back cover.
Operation
1. Front Panel Operation
a) Open and Close buttons and their Indicator Lights.
The open and close buttons allow the user to control
the valve locally. The indicator lights will show the
status of the ball valve, either open or closed.
b) Program Button
The program Button provides is used to include
(add) the water valve to a Z-Wave network, exclude
(remove) a water valve from a Z-Wave network, and
switch between water valve modes. The operation
of the program button is described later.
c) Status Light
The Status light gives an indication of the current mode or of any error conditions. Generally, if the water
valve is in a Z-Wave network, the Status light is turned off. The Status light displays the indications in a
cyclic manner, so zero, one, or more of the mode or error indications may be displayed sequentially and
repeatedly. The Mode indications are fast blinks while the indications for error conditions are slow blinks.
The mode indications are described on page 5, the error conditions can be found under section ‘Fault
Conditions / Troubleshooting’.
d) Power-On
At power-on, the Water Valve Status light should start blinking within 10 seconds (if not in a network). At
power-on, the water valve will return to the last commanded (via button press or Z-Wave command) position,
even if it has been changed by the manual handle. This is true even if power is interrupted while the valve is
changing positions.

CAUTION: If the ball valve is not yet installed in a water line, ALWAYS KEEP FINGERS AND
FOREIGN OBJECTS AWAY FROM THE BALL VALVE. Objects in the path of the closing valve
can damage the ball valve and the ball valve can cause serious personal injury.
2. Mode Indications
Water Valve Mode Number of Fast Blinks Comment
Automatic Network Wide Inclusion
(NWI) mode (Not available on some
versions)
1
NWI mode is the default mode at
initial power-on and is active for
approx. 30 minutes or until manually
exited
In-Network (Water Valve is in a Z-
Wave network in either Water Alarm
or Water Level mode)
2 Not repeated, only given at power on
or after inclusion
Out-of-Network (Water Valve is not in
a Z-Wave network) / Water Level
Mode
3
Out-of-Network (Water Valve is not in
a Z-Wave network) / Water Alarm
Mode
4 Default mode at initial power-on
3. Automatic Network Wide Inclusion (NWI) Mode
At power-on and before the WV-01 is included in a network, the NWI mode is active. This mode allows
automatic inclusion into an existing house network that has a Z-Wave controller supporting NWI mode.
Please refer to your controller’s user manual to determine whether or not NWI mode is supported.
NWI mode is stopped after one of the following conditions occurs:
The Water Valve is automatically included,
30-minute timeout, or
The Program button is pressed
By pressing the Program button, the user can perform a manual inclusion into the network (see below).
NWI mode is entered every time power is applied to the Water Valve, if it is not already a part of a Z-Wave
network (i.e., included).
4. Inclusion (Manual) in a Z-Wave Network
To manually add (include) the Water Valve to a Z-Wave network, you must have a Z-Wave controller. Follow
your Z-Wave controller User Manual to configure the controller for Inclusion mode.
When the Water Valve is not in a Z-Wave Network the Status light will be periodically blinking (3 or 4 times).
Once the controller is in Inclusion mode, press the Program Button to complete the inclusion process.

Note: Inclusion and Exclusion are always done at Normal Transmit Power Mode.
5. Exclusion from a Z-Wave Network
To manually remove (exclude) the Water Valve from a Z-Wave network, follow your Z-Wave controller User
Manual to configure the controller for Exclusion Mode.
Once the controller is in Exclusion Mode, press the Program Button once. The controller will indicate when the
Water Valve is excluded and the Status light will start flashing periodically (3 or 4 times).
Note: Inclusion and Exclusion are always done at Normal Transmit Power Mode.
6. Association with One or More Water Sensors
Once in a network, a smart controller can be used to associate water sensors with the water valve. Association
allows a sensor to control a Water Valve directly without going through a controller. Refer to your controller’s
documentation on how to associate devices.
Typically, when associated, the Water Valve receives a Basic Set Command (value = 0xFF) to close the ball valve
(when a Water Alarm is active.)
If a water sensor is not associated with the water valve, then a controller receives the message from the water
sensor and, in turn, sends a Binary Switch Command (value = 0xFF) to the Water Valve to close the ball valve.
7. Water Alarm Mode vs. Water Level Mode
The Water Valve is typically used in Water Alarm mode. This mode is the default mode from the factory and
provides protection in case of water leaks. The Water Valve will close when receiving a Basic Set Command
(value = 0xFF) from an associated water sensor. An associated water sensor will typically send a Basic Set
Command (value = 0x00) when its alarm has being cleared and it no longer detects water at its sensors.
However, in Water Alarm Mode, a Basic Set Command (value = 0x00) will not cause a Water Valve to open the
ball valve. Instead, the Water Valve will respond with a Z-Wave “Application Rejected Request” transmission.
This is because you must manually open the water valve after fixing the leak or checking to ensure that the leak
has actually stopped since water may have merely run away from the water sensor. In this situation, the Water
valve can be manually opened by either using the Open button or sending a Binary Switch Set Command to the
Water Valve.
The Water Level Mode has been implemented for special applications, such as trying to maintain a water level
within a certain range. In this mode, the Water Valve will close when receiving a Basic Set Command (value =
0xFF) from an associated water sensor, but will also open when receiving a Basic Set Command (value = 0x00)
after a pre-configured time (default = 60 minutes, can be changed on the controller side from 1 min to 22+ days
see page 8) from the latest close command. In this case, the Water Valve will respond with a Z-Wave “Request
Queued” transmission. This time can be configured by using the Configuration Command Class. The local water
probe connected to the Water Valve will only operate in Water Level Mode when the Water Valve is not in a
network. This is because Water Level mode is only intended for use with one sensor.
Note: The Binary Switch Set Command to open or close the valve will always operate immediately in either mode.

The above modes can be set using either the front panel buttons prior to being included in the network or by using
the Configuration Command Class (described below) after being included in the network.
To switch between Water Alarm mode and Water Level mode prior to network inclusion, do the following.
i. Hold the Program button down for 1 or more seconds
ii. While still holding the Program button, press the Open Button (for Water Level Mode) or the Close Button
(for Water Alarm Mode).
Note: This button press sequence is not available after network inclusion.
To switch between Water Alarm mode and Water Level mode after network inclusion, refer to the Z-Wave
Configuration Command Class described under the Z-Wave Operation section.
8. Manual Operation (No AC or Battery)
If a backup battery (for example, car battery) is not connected to the Water Valve backup power connector, the
Water Valve will not operate when power is not present to the AC/DC power converter (for example during
lightning storms). In this situation, the handle at the side of the Water Valve can be turned in the direction
indicated to turn off the water in an emergency.
With a charged backup battery, the Water Valve should be able to successfully operate with an associated water
sensor assuming that there is still a wireless route from the water sensor to the Water Valve. In other words, the
Water Valve will operate with a backup battery, if other relaying Z-Wave nodes are still operational (i.e., powered).
9. Z-Wave Operation (Advanced)
The following sub-sections provide specific Z-Wave information for the command classes implemented by the
Water Valve.
a. Basic Command Class, Version 1
The Basic Command Class is fully implemented and the Set command is described in the section titled
“Water Alarm Mode vs. Water Level Mode.” The Water Valve will respond to a Basic Get with a Basic Report
indicating the last known position of the ball valve (value = 0xFF indicates closed and 0x00 indicates open).
Note: If the valve position is not known by the WV-01 (for example because the Valve is changing position, or
because of a fault condition), the Basic Get will be ignored. The Water Valve will instead respond with a Z-
Wave “Application Busy. Try Again Later” transmission.
b. Binary Switch Command Class, Version 1
The Binary Switch Command Class is fully implemented. The Binary Switch Set Command causes the ball
valve to close with value = 0xFF and causes the ball valve to open with value = 0x00. A Binary Switch Report
will be sent upon completion of the open or close operation. The Water Valve will respond to a Binary Switch
Get with a Binary Switch Report indicating the last known position of the ball valve (value = 0xFF indicates
closed and 0x00 indicates open).
Note: If the valve position is not known by the WV-01 (for example because the Valve is changing position, or
because of a fault condition), the Basic Get will be ignored. The Water Valve will instead respond with a Z-
Wave “Application Busy. Try Again Later” transmission.

c. Manufacturer Specific Command Class, Version 1
The Manufacturer Specific Command Class is fully implemented. The Manufacturer Specific Get returns the
following information: Manufacturer ID: 0x0084 Product Type ID: 0x0213 (US) Product ID: (Version and Revision may vary)
d. Version Command Class, Version 1
The Version Command Class is fully implemented. The Version Get and Version Command Class Get return
the Version Report and the Version Command Class Report, respectively.
e. Configuration Command Class, Version 1
The Configuration Command Class is implemented to switch between Water Alarm mode and Water Level
Mode. Switching between these two modes uses Parameter 0 of the Configuration Command Class. The
Configuration command class can also be used to change the Water Level timeout (or hysteresis time)
between the latest close operation and an open operation. The hysteresis time uses Parameter 1 of the
Configuration Command Class.
Parameter 0 – Mode
Size: 1 Byte
Value = 0x00 (Water Alarm Mode), Default
Value = 0xFF (Water Level Mode)
Parameter 1 – Water Level Timeout
Size: 2 Bytes
Value = 0x0000 to 0x7FFF (0 to 32,767 minutes or 22+ days, negative values are ignored, default is 60 minutes)
f. Alarm Command Class, Version 2
The Alarm Command Class, Version 2, is fully implemented to signal that the main power (both AC main and,
if present, backup battery) has dropped out or has been applied. The Water Valve will continue to operate
with a 12V Backup battery while the battery is fully charged. Once the battery is discharged to a certain level,
the water valve will recognize this, and send the Voltage Drop/Drift Alarm Event. When running on a
discharged backup battery, the Water Valve will periodically send the Voltage Drop/Drift Alarm Event, but will
not be otherwise functional. If main power is reapplied or a charged battery is connected, the Water Valve will
send the Power Reapplied Alarm event within 10 seconds.
If there is no backup battery connected to the Water Valve when main power has dropped out, the Water
Valve will attempt to send a Voltage Drop/Drift message using residual power in the circuit.
The Alarm Command Class uses the following command class alarms and events:
Z-Wave Alarm Type: Power Management Alarm (0x08); Note: the WV-01 returns 0x80 for the Alarm
Type Supported Get Report
Z-Wave Alarm Events: Voltage Drop/Drift (0x05)
Power has been applied (0x01, only sent after Voltage Drop/Drift event)
Z-Wave Alarm Status: 0xFF, Enabled (Factory Default State)
0x00, Disabled

Note: The Water Valve will only send the Alarm Report Command unsolicited if it has previously received the
Alarm Set Command. In this case, the Alarm Report will only be sent to the last node from which it received
the Alarm Set Command (i.e., it won’t be ‘broadcast’ to the Z-Wave network.)
g. Application Status Command Class, Version 1
The Application Status Command Class is implemented to allow the Water Valve to signal other devices that
the Water Valve is busy or has rejected a request because of its current state. These responses are
described above in sections 7, 9a, and 9b.
10. Fault Conditions / Troubleshooting
The Status LED provides the following fault indications represented by 2 or more slow, periodic blinks.
Generally, these should never occur. The presence of one of these other status indications may mean
that something is wrong with the Water Valve hardware.
