Smart Dry Contact Switch - Operating Instructions 1
Device description
WiDom Smart Dry Contact Switch can turn ON and OFF equipments with an independent power supply,
such as solenoid valves (e.g. gas, water and irrigation), power operated valves etc.
WiDom Smart Dry Contact Switch is very easy to install and works with both momentary and toggle
switches.
The device is equipped with contact protection technology (Zero Crossing) which reduces the electrical
stress on the relay contacts and ensures a longer life. The open / closed switching of the device always
occur when the instantaneous value of voltage is 0.
It operates in any Z-Wave network with other Z-Wave/Z-Wave Plus certified devices and controllers from
any other manufacturer. As a constantly powered node, WiDom Smart Double Switch will act as repeater
regardless of the vendor in order to increase the reliability of the network.

LED status indicator
The system includes an RGB LED that shows the device’s status during installation:
Solid RED: the device is not included in any network
OFF: the device is already associated to a Z-Wave network
Blink GREEN: the device has sent an unsolicited Multilevel Frame to Lifeline group
Blink YELLOW: the device has sent an unsolicited Meter Frame to Lifeline group
Blink VIOLET: the device has sent a command to the association device. The number of blinks is equal to
the ID Association group
Sequence of GREEN-BLUE Learn Mode for inclusion
Sequence of RED-BLUE Learn Mode for exclusion
INFO: The Learn Mode status is activated or deactivated by a single click on the integrated button.
TIP: To test if the electrical connections are correct, before the inclusion of the device, while pressing n
times the external switch, the RGB LED should flash green for the same amount of times. If it does
not, check the wire connections.
Including the device into an existing Z-Wave network
WiDom Smart Dry Contact Switch is compatible with all Z-Wave/Z-Wave Plus certified controllers. 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 directly connected to the controller) and Normal Inclusion.
By default, the inclusion procedure starts in Normal Inclusion mode and after a short time out the procedure
continues in Network Wide Inclusion mode that lasts for about 20 Seconds.
If you are using the WiDom Multi Sensor Room Controller you can include the device in the preferred room
by clicking on the button and opening the inclusion interface.
Before including the device the LED status indicator is solid RED. The procedure of inclusion is activated by
clicking Add in the inclusion interface and by pressing any sequence of click on the integrated button. As
soon as the inclusion procedure initiates the LED indicator starts a sequence of GREEN-BLUE blinks. The
device is included in the network when the LED status is OFF and the interview is completed.

Excluding the device from a Z-Wave network
Only a controller can remove the device from the network. After activating the exclusion function by the
controller, the device can be removed by setting it in Learning Mode.
If you are using the WiDom Multi Sensor Room Controller, the procedure of exclusion can be activated by
Removing a node from the Z-Wave network and any click sequence on the integrated button; as soon as
the exclusion initiates, the LED indicator starts a sequence of RED-BLUE blinks. The device is excluded from
the network when the LED status indicator is solid RED and the App_status in the interface is OK.
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: 6 consecutive clicks on the integrated button
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).

Smart Dry Contact Switch - Operating Instructions 6
Firmware Update
The system supports over-the-air firmware updates that do not require the device to be removed from its
location. The firmware update can be activated from all certified controllers supporting version 2 of the
Firmware Update function.
WARNING: The system will be rebooted at the end of the firmware update procedure. It is advisable to
carry out the firmware update procedure only when necessary and following careful planning of the
intervention.
Controlling the device
The WiDom Smart Dry Contact Switch can turn ON and OFF by using an external switch, or from remote
through a controller
Controlling the Smart Dry Contact Switch by External Switches
WiDom framework recognizes the number of clicks or hold event on the external switch and can be
configured to perform different actions based on the identified event.
External switch: External button or switch connected to the Line Signal terminal.
Click: If the external switch is a button (when pressed it autonomously returns to the initial position), a
click means pressing and then releasing it. If the external switch is bistable (when pressed it does not
return to the initial position), a single click means one single flip of the switch.
Hold:Applies only when the external switch is a normally opened button and occurs when the
pressure on the button lasts longer than a click.
Control Actions –Result Event
Holding the external switch changes the status of dry contact and return to the previous status as
soon as the button is released.
A single click on the external switch turns ON/OFF the load.
Controlling the Smart Dry Contact Switch by the controller
The WiDom Smart Dry Contact Switch can be controlled by any Z-Wave / Z-Wave Plus certified controller
available in the market.
In the figure below, is represented how the device will appear once included into the WiDom Multi Sensor
Room Controller.

Smart Dry Contact Switch - Operating Instructions 7
The control panel show the load status. The ON/OFF buttons in the control panel allow to turn ON/OFF the
load connected to the dry contact.
The device status is typically updated in case of status change. Nevertheless, it is possible to refresh the
shown status by using the Refresh Button .
The device configuration parameters and settings can be accessed by using the Configuration Button .
Associations
WiDom Smart Dry Contact Switch can control other devices like other relays or dimmers. WiDom Dry
Contact supports 4 association groups:
INFO: Association ensures direct transfer of control commands between devices, and is performed
without participation of the main controller.
TIP: WiDom Smart Dry Contact Switch can control up to 8 devices for each group. To avoid network
delays, we recommend limiting the amount of associated devices to no more than 5 per group.
INFO: If you want to add the device within the first group and you are using the WiDom Multi Sensor
Controller, the device association group can be configured as follows: 1) Click Configuration button,
2) select Association section, 3) click the button to Add a new device to the group or click on the
button to Remove a device.
