INSTALLATION

C1 C2ROk

C1 C2ROk

• The instrument is supplied with the battery not inserted to avoid
wasted consumption. Extract the battery from its packing and insert
it into the housing located behind the instrument so that pole (+)
is visible as shown in the figure. Then secure the closure cover,
turning it clockwise.

English

• Using a pointed object press key “R”

C1 C2ROk

to perform a reset. All the segments
of the display will light for a few
seconds and then the instrument shows
the version of the firmware and the type of instrument.

• At this point it is possible to insert the parameters necessary for the
instrument to work correctly:

− language

− date format

− date

− time

Setting language

It is possible to choose from 5 languages:
Italian ´ English ´ Spanish ´
French ´ German

• Connect the load and the power supply as illustrated in section

The instrument then goes into normal
operational status and is ready to work.
The display shows the values for the date,
time, status relay, day of the week (on
the first line in letters and lower down in
numbers) and the DST/CET symbol.

Note: if the instrument is not fed by
the mains, on the first line of the

In this condition backlighting is not active

C1 C2ROk

ON/OFF Events

ON and OFF events consist of switching the relay to the on or off
position.
They may be daily (every day at the same time) or weekly (one or more
days during the week, each week).

IMPULSE events

An impulse event can be an on or off type and may last for a maximum
of 59 second:

ON OFF

At the end of the on impulse the relay will always be in the off status; at
the end of an off impulse the relay will always be in the on status.
An impulsive event can be interrupted following a manual operation.

CYCLE events

A cycle event is a programme which repeats itself over a preset period
of time (maximum duration 1 week) during which there is a succession
of on and off switching.
The cycle programme always starts from the on status and always ends
in the off status. The duration of the on and off status cannot be less

than one minute.
The cycle event may be interrupted following a holiday event (relay
status:off), a manual operation, a date/rime change, automatic updating
of CET/DST time (we recommend disabling the automatic time change
when using the cycle programme).

HOLIDAY events

A holiday event allows you to enter individual days or holiday periods
during which all the set programmes shall not be carried out and the
relay shall be in the off position.
Holiday events always start at 00:00 on the starting day and end at
23:59 on the last day of the holiday.
Holiday events are interrupted in the case of manual operations on
output.

Programming priority

In automatic function mode the instrument behaves as foreseen by the
entered programmes. Should there be conflict between programmes
(different events starting at the same moment) the instrument will only
run the one with the highest priority, according to the following table
(1 maximum priority):

Cycle 1 -

Impulse 2 3

ON or OFF 4 5

Programmed events which starting during an event already in progress
(holiday, cycle) are ignored.
In the case of non-instantaneous (holiday, cycle, impulse) the device
always completed the started programme before managing the next.
Exceptions to this are cases in which:

- a holiday event occurs while executing a non-instantaneous
programme

- there is a change to manual operation while executing a non­instantaneous programme. In this case all the programmes running are
interrupted and if there is a lock or random on the channel, execution
of all programmes is disabled until manual procedure is deactivated

Programmes that are active when one of these exceptions occurs are
interrupted and will not be restored. When execution is interrupted, the
relays still maintain status unless entering a holiday day (or period).
