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 conguration” are
satised: room probe/external thermostat (congurations 1-2-3), ow switch (conguration 2), puer thermostat/ntc (10 kΩ ß3435)
(conguration 4-5) or boiler thermostat/ntc (10 kΩ ß3435) (conguration 2-3). If all devices present are satised 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 ame 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 ame goes into P1 and stays there until the programmed “Eco shutdown t” time has elapsed and if the conditions are still
satised, it goes into the shutdown stage. The ECO switch o countdown resets if one of the devices boosts power again.
When switch o starts the panel displays: O - Eco Active - small ashing ame.
Once the boiler has reached the o condition, the panel displays OFF-ECO with the extinguished ame symbol.
To restart from ECO the following conditions must be satised simultaneously:
• Power demand
• After 5 minutes from the beginning of shutdown.
• TH
2
O < TSetH
2
O.
• If the domestic hot water (DHW) demands power the rst 5’ are ignored and the boiler restarts as needed.
NOTE: In conguration 4 - 5 the Auto Eco mode is enabled automatically. Even when one sets the “summer” function in conguration 2 - 3
it is enabled automatically. In the cases where it is designed to be active, it is not possible to deactivate the mode.
