4.6.1 Menu 02 – set clock
The electronic control device has a lithium battery mod. CR2032 of 3 Volt inside. It allows the internal clock with
own autonomy; if the clock signal does not appear when the stove is off or when switching the stove again a series
of "0000" appears, it means it has to be substituted and you need to call one of our service point authorised for its
substitution.
4.6.3 Menu 03 – enable chrono
It allows to enable and disable all the thermostat functions programmed; with the set ON you
activate this function and it appears the led [ D ] related to it.
When the daily, weekly, or week-end program is set you can see
on the upper right side of the display it appears the led [C].
By accessing the submenu: DAY PROGRAM, the daily
chronothermostat functions can be enabled/disabled and set.
It is possible to set two operation phases delimited by the times
set according to the following table where the OFF setting tells
the clock to ignore the command.

By accessing the submenu: WEEK PROGRAM it is possible to
enable/disable and set the weekly chronothermostat functions.
The weekly programmer has 4 independent programmes whose
final effect consists of a combination of the 4 programmings.
The weekly programmer can be activated/deactivated; also, by
setting OFF in the times field, the clock ignores the
corresponding command.
Carry out programming making sure not to overlap the
hours of activation and/or deactivation on the same day
in different programmes.
