The "sun" symbol (with indication of the lit bars) indicates that heating is enabled; whereas
the "moon" symbol (bars off) indicates disabling periods.
The hour programming is logically in series with the ambient thermostat inputs. This
means that the boiler will perform heating only if the TA contact is closed and if the
programming is in the enabled periods (sun).
Programmes and zones are associated by parameter P61.
In presence of the remote control and without supplementary boards, the associated zone
is always zone1. When a remote control is connected, the hour programming of the
associated zone (and of the water heater if available) will not be shown by the boiler
display as it is set directly through remote control.
Programming procedure
To access programme display or editing mode, press “PROG” key
repeatedly:
-
,
press twice to access heating programme for zone 1;
-
,
press three times to access heating programme for zone
2;
-
,
press four times (only for RTFS with P3=3) to access the
programme for maintaining water heater.
Each time the “PROG” key is pressed, its icon flashes displaying the
programme to which access is required (displaying the current
operation period). Press the “ok” key to access actual programming.
Then select the day(s) of the week to be edited using the “+/-
heating” key and confirming as usual with the “ok” key (the icon
associated to the day(s) will stop flashing and will remain on steady).
It is now possible to associate the day/night
level (by means of the “sun/moon” key) with
the desired time, using the “+/- heating” key:
In case single days are programmed, when exceeding the 24 h use
the “+/- heating" key and the system will automatically switch to the
next day without having to repeat the whole sequence.
Press the "reset" key to change day or programme immediately.
Press it twice repeatedly to quit the programme completely and
return to the main page.
