8.13 NOTES FOR TIMER OPERATION

• Start-up with the timer always takes place with the last temperature and ventilation settings (or with default 20°C and V3

settings in the event they have never been changed).

• It is possible to set the shutdown time from "ignition time + 10 minutes" up to 23:50. If 24:00 is set as shutdown time, the stove

will not switch off (use this shutdown time, for example, when the next day is programmed to continue from 00:00).

• If the shutdown time is not already memorised, it proposes a start-up time in + 10 minutes.

• A timer programme switches the boiler off at 24:00 of one day and another programme switches it on at 00:00 of the next day:

the boiler stays on.

• A programme proposes a start-up and shutdown in times included within another timer programme: if the boiler is already on,

start will not have any effect, while OFF will switch it off.

• In the boiler on and timer active condition, press the OFF key and the boiler will switch off, it will switch on automatically at

the next time set on the timer.

• In the boiler off and timer active condition, press the ON key and the boiler will switch on, it will switch off at the time set on

the active timer.

8.14 AUTO ECO MODE (SEE SECTION F-G SETTINGS MENU A PAG. 13)

To activate the "Auto-Eco" mode and adjust the time refer SETTINGS MENU a pag. 13.

The possibility to adjust the " t Off Time Eco" comes from the need to ensure proper operation in the various rooms the boiler can

be installed in and prevent continuous shutdowns and start-ups in the event the temperature is subject to sudden changes (air

currents, poorly insulated rooms, etc.).

The ECO switch off procedure is automatically activated when the power recall device is activated (Room probe +1°C or external

thermostat with open contact, see Fig. 19). "t Off Time Eco" time decrease starts (5 minutes by default, see Fig. 20, and can be

modified from the "Settings" menu). During this phase the panel view is activated ON with the small flame and alternates chrono

(if ON) - active Eco.

Fig. 19 - Active eco 1

On the upper display the minutes for the Eco Stop countdown are shown. The flame goes to P1, where it remains until the set "t

Off Time Eco" time is over and, if conditions are still met, it switches to the switch-off process. The ECO switch-off countdown is

reset if one of the devices resumes recalling power.

When the switch-off procedure begins, the panel shows: Off - Active Eco - small flashing flame (see Fig. 21).

When the stove is switched off, the panel shows active OFF-ECO with the flame icon off.

For an ECO switch on, the following conditions must be met simultaneously:

• Room probe -1°C or external thermostat with closed contact (for at least 20" to avoid false recalls).

• After 5 minutes from the beginning of the switch-off procedure.
