Introduction
WiDom Universal Relay Switch is a Z-Wave certified “in wall device”.
The device is based on the use of a latching relay that is combined with an innovative design and effective
implementation to ensure extremely low energy consumption.
WiDom Universal Relay Switch is designed for being installed in junction boxes, flush mount boxes and near
lights. WiDom Universal Relay Switch is an ON\OFF device and can be used as both a local and remote
switch. It supports two wire connections, which allows it to be installed into any existing system without the
need to change the wiring.
At the same time, it is completely configurable so that it can adapt to the most varied needs while also being
ready to be used without needing additional configurations in order to operate.
Thanks to the framework developed by WiDom, the various types of “events” on the “External Switch” can be
recognised and associated to actions to be performed on the device, and\or on any associated devices and\or
on all devices on the network. The events that the system recognises are the number of “clicks” or hold on the
External Switch.
Although Z-Wave is quite new technology, it has already become recognizable and officially binding standard,
similarly to Wi-Fi. Many manufacturers in various industries offer solutions based on Z-Wave technology,
guaranteeing their compatibility. This means that the system is open and it may be extended in the future.
External Switch: Any switch, button or traditional wall control connected to the device in order to turn it
on or off.
Events: The actions performed on the external Switch: Clicks or Hold.
Click: If the external switch is a button (when pressed it returns to the start position by itself), a click
means pressing and then releasing it. If the external switch is a bistable one (after being pressed it does
not return to the original position), a single click means one single flip of the switch.
Hold: This applies only to buttons that are normally open and that are identified as such when the
pressure phase lasts at least 1,5 seconds.
Device in ON\OFF status refers to the fact that the latching relay contact is in the Open\Close position.

Installation
WARNING: WiDom Universal Relay Switch must be installed by a certified electrician in compliance with
the safety requirements set forth in national law regulations.
DANGER: WiDom Universal Relay Switch must be connected to 240VAC. Before performing any
installation operations, make sure the main switch on the meter is set to OFF.
DANGER: Any procedure that calls for the use of the (R) and (B) service buttons is related only to the
installation phase and is to be considered a service procedure that must be performed by qualified
personnel. This operation must be performed with all necessary precautions for operating in areas with a single
level of insulation.
WARNING: Do not connect loads that exceed the maximum load permitted by the relay contacts. In the
case of greater loads, WiDom Universal Relay Switch may be used to control an external relay or a
contactor. For non-resistive loads, the maximum load must be appropriately reduced.
WARNING: All connections must be performed according to the electrical diagrams provided
WiDom Universal Relay Switch Activation
1) Make sure the mains switch is set to the OFF position
2) Connect the device based on the diagrams provided
3) Close the electrical box that contains the device
4) Turn the system back on
5) Include the device in the Z-Wave network
TIP: The antenna must not be shortened, removed or modified. To ensure maximum
efficiency, it must be installed as shown. Metal equipment near the antenna can
negatively affect reception. Each WiDom device is a node in a mesh network. If there are
metal obstacles, the obstacle can often be overcome with a further triangulation node.

TIP: In this mode, the device can be installed near the light to be controlled and the existing switch is
replaced with a normally closed button. For a light controlled from several points, all of the switches
should be replaced with normally closed buttons. Please note that in this case another connection that may
work is shown in figure CD.2 where the necessary modified connection for just one of the switches is
represented.
TIP: In order to control a neon tube with a traditional ballast and a starter and in general with non-pure
resistive loads or with long wire connections a WiDom Switch Helper should be connected in parallel to
the load as shown in diagram C.
INFO: If using a secondary load supply system, it must be connected as in diagram D. The supply
voltage can be either AC or DC within the limits permitted by the relay contact, up to 250 V in AC and
up to 30 V in DC.
WARNING: The line connected to the relay contacts must be suitably protected from short circuits and
overloads connected to a possible failure of the connected load.

Reset to the factory settings
The device can be reset to the original factory settings using one of the following methods:
Method 1: Remove the device from the Z-Wave network
Method 2: Six consecutive clicks on button (B)
Method 3: Set parameter 61 to value 0 - FACTORY RESET (see paragraph 0).
INFO: If the reset is performed while the device is still part of a network, it notifies the other devices that
it has been removed (Device Reset Locally Notification).If WiDom Universal Relay Switch receives a
removal notification from another device, it will delete the removed device from its own associations.
Including the device into an existing Z-Wave network
WiDom Universal Relay Switch can be included and operated in any Z-Wave network with other Z-Wave
certified devices from any other manufacturers. As constantly powered node WiDom Universal Relay Switch
will act as repeater regardless of the vendor in order to increase reliability of the network.
The device supports both the Network Wide Inclusion mechanism (which offers the ability to be included in a
network even if the device is not in the direct range of the controller) and Normal Inclusion.
By default, if the device is not included in any network, as soon as it is powered the Network Wide Inclusion
procedure starts and lasts for about 1 minute. The procedure can be reactivated at the next device restart or
by pressing the (R) button.
If the used controller does not support the Network Wide Inclusion functionality, the device may be included in
the network through Normal Inclusion by pressing the (B) button once or three times or alternatively by pressing
the external switch once.
INFO: During the inclusion procedure activated by a single click on the external switch, the system also
automatically determines the switch type (See parameter No. 62).
Excluding the device from a Z-Wave network
Only a controller can remove a device from the network. WiDom Universal Relay Switch is compatible with all
Z-Wave certified controllers. After the exclusion function has been activated from the controller, the device can
be removed, putting it in Learning Mode by pressing the (B) button once or three times or more conveniently
by using the external switch after having enabled the learning mode activation from external switch (see
parameter N°65).
Request network update
If there is a SUC (Static Update Controller) or SIS (SUC ID Server) in the network, a network update can be
requested by pressing the external switch four times.
Associations
WiDom Universal Relay Switch can control other devices like other relays or dimmers. WiDom Universal Relay
Switch supports 5 association groups:
Group 1: devices that will be notified of changes in its status
Group 2: devices that will be controlled by a single click on the external switch
Group 3: devices that will be controlled by a double click on the external switch
Group 4: devices that will be controlled by a triple click on the external switch
Group 5: devices that will be controlled by hold on the external switch
TIP: WiDom Universal Relay Switch can control up to 16 devices for each group. To avoid network
delays, we recommend limiting the amount of associated devices to no more than 5 per group.

Controlling the device with an external switch
With WiDom devices, the normal switches/buttons found in a traditional electrical system can become
intelligent control systems.
WiDom Framework recognises the number of clicks or hold event on the external switch and can be configured
to perform different actions based on the identified event.
Controlling the device via the Z-Wave network
All Z-Wave controllers can control the device using the Basic Set command.
The behaviour of the device based on its status and on the commands received from the network can also be
configured.
Alarms management
WiDom Universal Relay Switch can also be configured to react to alarm notifications from sensors on the
network. WiDom Universal Relay Switch recognises and complies with Notification V3 Report frame alarm
notifications.
INFO: By default, WiDom Universal Relay Switch reacts to smoke, heat, water and home security alarms
generated by others Z-Wave sensors in the system. The reaction type: ON,OFF or FLASHING can be
configured as needed.
Switch ALL ON\OFF
By default, WiDom Universal Relay Switch accepts Switch All ON\OFF commands.
Timer option
WiDom Universal Relay Switch has a built-in configurable timer for programmed switch-off.
Troubleshooting
By pressing the (B) and (R) buttons at the same time and then releasing (R), the system starts a check
procedure that can produce one of the following results:
1. If the device is included in a network, it switches from ON to OFF repeatedly with equal ON and OFF
times of 2 seconds each.
2. If the device is not included in a network, it switches from ON to OFF repeatedly with an ON time of 2
seconds and an OFF time of 6 seconds.
INFO: The procedure described lasts until the (R) button is pressed again.
Configurations
Controlling the device by external switch
Clicks on the external switch turn the connected load on or off depending on the initial status, on the number
of clicks and on the device configuration. The actions that will be performed on the associated devices and on
all other devices on the network can also be configured.
INFO: As soon as the click recognition process has completed, the device will be set to the desired
status, any switch all on\off actions will be performed and the associated devices will be controlled.
