frequencies. To add the device, click the button three times in a row. Success
is indicated by a green blinking LED. Complete the adding (inclusion) by
following the instructions for the gateway. This device supports Z-Wave Smart
Start. Please scan the QR Code on the device label before adding if your
gateway supporting Smart Start.
Important safety information
Please read this manual carefully. Failure to follow the recommendations in this manual may be dangerous or may violate the law. The manufacturer, importer, distributor and seller shall not be liable for any loss or damage resulting from failure to comply with the instructions in this manual or any other material. Use this equipment only for its intended purpose. Follow the disposal instructions. Do not dispose of electronic equipment or batteries in a fire or near open heat sources.
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 Quick-Start
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 Z-Wave device regardless of brand and origin as long as
both are suited for the same frequency range.
This device supports secure Z-Wave communication. It will communicate with
other Z-Wave devices secure as long as the other 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.
Product Description
The BVS is a motor to retrofit existing and installed ball valves into smart
water controlling devices. The motor is powered by a 12 V external power
supply or – optionally – a battery block. The variable clamps allow mounting
the device even in complex pipe installations, the patented motor coupling
ensures easy installation and precise long-term operation. The device can
operate in difficult environmental conditions, even submerged under water and
allows directly connecting one additional local water sensor pad by cable.
The device can operate in two modes:
Stand-Alone: No further wireless connectivity is needed. A single click on the button opens and closes the valve. Clicking the button during open or close operation stops movement. The next click will continue the operation. Escaping water is detected by the external sensor pad and the valve it shut off accordingly. The button on the device allows clearing the alarm. Device in factory reset state operate in stand-alone mode without further configuration.
Z-Wave Network Mode: The device is added to a Z-Wave network as Z-Wave Binary Switch Device. Adding can be achieved using Smart Start or Classical Z-Wave Inclusion. All functions of the Stand-Alone mode remain active. Leakage or Temperature Alarms are forwarded to the Z-Wave Gateway and other Z-Wave device are able to control the motor.
Calibration
The BSV is able to both measure the rotation angle and detect the end
positions of the handle. It can therefore gently reach the end positions to
avoid any friction and unneeded mechanical stress. Whenever the device is
powered or repowered it will do a calibration run first. To start the
calibration just hit the button once. You will witness some movements of the
handle and after 10…20 seconds the device is ready to operate. Calibration
requires that the BVS is mounted to a ball valve. The device will detect if no
valve is present and stop calibration. In this case the operation of the
handle (both by button and by wireless command) is disabled.
Prepare for Installation / Reset
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: Keep the button pressed for 10 seconds. Then click the button 5
times. The yellow LED will light up to confirm factory reset.
Installation
- Make sure the power is disconnected.
- Choose the right size of the fork according to the size of the valve handle.
- Make sure the two tightening knobs and the handle face opposite direction (handle must have clearance to move)
- Tighten clamps with hands while holding down the BVS.
- If needed – unplug the dust cover and connect the local Water Sensor Probe.
- Connect the DC Power Adapter to the power wire coming from the BVS and tighten the water seal.
- Plugin the power adaptor into 230 V power socket.
The BVS is designed for outdoor deployments. To prevent mis-operation by rain etc. users can disable the touch sense button. Once disabled the only accepted operation of the button is the reactivation. The operation of the touch sense button can also be enabled/disabled using Z-Wave configuration parameter #67. Enabling and disabling is performed by holding down the button for 3 seconds followed by three short clicks on the button.
Inclusion/Exclusion
On factory default the device does not belong to any Z-Wave network. The
device needs to be added to an existing wireless network to communicate with
the devices of this network. This process is also called Inclusion.
Devices can also be removed from a network. This process is also called
Exclusion. Both processes are initiated by the primary controller of the
Z-Wave network. This controller is turned into inclusion respective exclusion
mode. Inclusion and Exclusion is then performed doing a special manual action
right on the device.
Adding
When using Smart start just scan the QR code on your device. When using
classical Z-Wave inclusion, triple click the button. Success is indicated by a
green LED blinking for one second plus two short beeps by the buzzer
Removing
Triple click the button. Success is indicated by a green LED blinking for one
second plus two short beeps by the buzzer.
Usage
Button Usage
The device has one single button with a three color Led built in. You can
click on the button or keep the button pushed for some seconds. The BVS will
help you counting the second by beeping every second.
The device is designed for outdoor use and must prevent malfunction caused by
water drops on the button. Hence, please push the button firmly (not too shy)
even for clicking so that the touchless button will recognize your finger.
Local or remote open and close of the valve
Single click on the button starts the opening or closing action. Clicking the
button during phase of movement stops the movement. Another click of the
button resume operation. (Please note that first operation of valve after
power on will always cause calibration. Refer to chapter ‘calibration’ for
more details.)
Z-Wave commands allow opening and closing of the valve using ON/OFF commands.
Local Alarm
When the local sensor probe is attached it will detect water and cause an
alarm. The alarm is reported to a Z-Wave controller – when in Z-Wave network
mode – and it causes the valve to close. Blinking of red Led plus frequent
sound of the buzzer indicate the alarm status. You can’t operate the valve
anymore before alarm is cleared.
To clear alarm perform two short clicks on the button (the buzzer will stop
and the LED blinks green) and then keep the button pressed for two seconds
(count two beeps). Triple green link of the LED confirms clearing the alarm.
Local Sensors
The device has built-in sensors that send sensor values to the Z-Wave Gateway
when connected.
- Temperature Sensor Value
- Temperature Overheat Alarm (0x04-0x02, heat detected)
- External Sensor Probe
- Water Leak Alarm (0x05- 0x02 leak detected)
Quick trouble shooting
Here are a few hints for network installation if things don’t work as
expected.
- Make sure a device is in factory reset state before including. In doubt remove from network before adding to network again.
- If inclusion still fails, check if both devices use the same frequency.
- Remove all dead devices from associations. Otherwise you will see severe delays.
- Never use sleeping battery devices without a central controller.
- Do not poll FLIRS devices.
- Make sure to have enough mains powered device to benefit from the meshing.
Association – one device controls other devices
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 of the event, all devices stored in the
respective association group will receive the same wireless command wireless
command, typically a ‘Basic Set’ Command.
Association Groups:
| Number | Max Nodes | Description |
|---|---|---|
| 1 | 5 | Lifeline. All alarms and status information that shall be sent to the |
gateway
2| 5| Switch Devices when Water Valve is operated (either local or by sensor o
by wireless command)
3| 5| Switch Devices when water leak was detected
4| 5| Switch Devices when temperature raise above threshold
5| 5| Switch Devices when temperature falls below threshold
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 2 byte value the same logic applies: Values greater than 32768 may needed to be given as negative values too.
