AUTO ECO MODE (SEE SECTION F-G)
To activate the "Auto Eco" mode and adjust the time refer see section f-g.
The possibility to adjust the "ECO shutdown t" 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 shutdown procedure is activated automatically when all the power demand devices involved in the "system configu-
ration" are satisfied: room probe/external thermostat, flow switch, puffer thermostat/ntc (10 kΩ ß3435) or boiler thermostat/
ntc (10 kΩ ß3435). If all devices present are satisfied the "ECO shutdown t" time decrease starts (by default 10 minutes, it can
be changed within the "Settings menu"). During this stage the panel displays ON with a small flame and alternately Chrono (of
active) - Eco active. The minutes indicating the countdown for the Eco Stop are shown at the top of the display. The flame goes into
P1 and stays there until the programmed "Eco shutdown t" time has elapsed and if the conditions are still satisfied, it goes into the
shutdown stage. The ECO switch off countdown resets if one of the devices boosts power again.
When switch off starts the panel displays: Off - Eco Active - small flashing flame.
Once the boiler has reached the off condition, the panel displays OFF-ECO with the extinguished flame symbol.
To restart from ECO the following conditions must be satisfied simultaneously:
• Power demand
• After 5 minutes from the beginning of shutdown.
• TH2O < TSetH2O.
• If the domestic hot water (DHW) demands power - if envisaged - the first 5' are ignored and the boiler restarts as needed.
NOTE: In configuration 4 - 5 the Auto Eco mode is enabled automatically. Even when one sets the "summer" function in configura-
tion 2 - 3 it is enabled automatically. In the cases where it is designed to be active, it is not possible to deactivate the mode.

PROGRAMMED MODE (TIMER) - MAIN MENU
Setting the current day and time is essential for the proper operation of the timer.
There are six TIMER programmes, for each one the user can decide the start-up and shutdown time as well as the day of the week
in which it is active. When one or more programmes are active, the panel alternately displays the boiler status and TIMER "n"
whereby "n" is the number relating to the activated timer programmes, separated from each other with a dash
Example:
• TIMER 1 Timer programme 1 active.
• TIMER 1-4 Timer programmes 1 and 4 active.
• TIMER 1-2-3-4-5-6 Timer programmes all active.
