USER MANUAL
The digital time switches of DW series are electronic devices for the management of the electrical utilities over time. They allow the time
programming (periodicity: daily or weekly).
DW1 is equipped with a relay (channel 1) while DW2 is equipped with two relays (2 independent channels).
DW time switches have a Bluetooth interface that allows it to be coupled with mobile devices (smartphone or tablet). Thanks to the free app
that can be downloaded from the AppStore and Google Play stores, it is possible to program and make settings directly on your smartphone,
and then transfer all the data to the time switch.
The reverse procedure is also possible, i.e. to copy the programming of a time switch on your mobile device.
The backup battery allows you to keep the settings even in case of black-out and can be replaced through the cover on the back of the time
switch.
DW time switches are devices of electronic type that perform actions of 1B type , intended to operate in environments with III overvoltage
category and pollution degree 2 in accordance with EN 60730-1 standard.
