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).
• Start-up time ranges from 00:00 a 23:50
• 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.

AUTO ECO MODE (SEE SECTION 8F AND 8G)
To activate the "Auto Eco" mode and adjust the time refer to section 8 f and 8 g respectively.
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 configuration" are satisfied: room probe/external thermostat (configurations 1-2-3), flow switch
(configuration 2), puffer thermostat/ntc (10 kΩ ß3435) (configuration 4-5) or boiler thermostat/ntc (10 kΩ
ß3435) (configuration 2-3). 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 configuration 2 - 3 it is enabled automatically. In the cases where it is designed to be active, it
