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.

Safety information
INFO: WiDom Smart Dry Contact Switch is designed to be installed in flush mounting junction boxes or
close to the load to be controlled.
WARNING: WiDom Smart Dry Contact Switch must be installed by electricians qualified to intervene
on electrical systems in compliance with safety requirements set out by the regulations in force.
DANGER: WiDom Smart Dry Contact Switch must be connected with a voltage of 230 VAC, before
carrying out any operation, please make sure the power main switch is in OFF position.
DANGER: Any procedure requiring the use of the Integrated Button 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 actuator element.
WARNING: All connections must be performed according to the electrical diagrams provided
WARNING: WiDom Smart Dry Contact Switch must be installed in norm-compliant systems suitably
protected from overloads and short circuits.

Electrical Connections diagram
The device must be supplied by phase and neutral.
Connections must be done following one of the diagrams below: if you need to control a Load connected on
a different power supply system you must follow the diagram on the right side.
Device Installation
1) Make sure the main switch is set to the OFF position
2) Connect the device based on the diagrams provided
3) Turn the main switch to the ON position
4) Include the device in the Z-Wave network
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.

WARNING: The power line must be opportunely protected from short-circuits and excess load due to a
failure of the load.
TIP: The antenna must not be shortened, removed or modified. To ensure
maximum efficiency, it must be installed as shown. Large size metal equipment
