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

English

category and pollution degree 2 in accordance with EN 60730-1 standard.

Programs types

• Program ON/OFF: is composed of a switching of the ON relay and of a subsequent switching of the OFF relay. It can have a daily period

(everyday with the same modes), weekly (every week with the same modes).

• PULSE ON Program: is an ON relay switching for a maximum duration of 59 seconds. It can have a daily period (everyday with the same

modes), weekly (every week with the same modes).

• PULSE OFF program: is a relay switching OFF for a maximum duration of 59 seconds. It can have daily period (everyday with the same

modes), weekly (every week with the same modes).

• HOLIDAY program: is a period of time defined by a start time and an end time within which all programmed switchings (of that channel)

are disabled. The relay is in OFF position (OFF holiday) or in ON position (ON holiday).

 Important: on the same channel can’t coexist ON pulses and OFF pulses (if an ON pulse is already present, it’s not possible to save a

holiday OFF program and vice versa).
