AUTO ECO MODE
Auto-Eco mode changes the behaviour of the boiler in automatic mode, i.e.:
when the room temperature set by the user has been reached (the temperature is read by the probe on board the product or by the
external thermostat) the boiler modulates at power 1 for a brief period of time; if the temperature remains constant or greater than the
set one, the boiler switches o. On the other hand, if the room cools down and requires more heat, the boiler automatically switches back
on (not before time interval required to cool the boiler).
This mode is only advisable if the product is operating in highly insulated rooms or where heat dispersion over time is minimum, as it
allows you to optimise boiler consumption without wasting fuel.
To activate the “Auto Eco” mode and adjust the time refer to points “f” and “g” respectively.
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.
h - Pump On T (only for expert users)

• Scroll to "Pump On T" using the arrows.
• Press "menu" to conrm.
• Modify the °C with the + - keys.
• Press "menu" to conrm and "esc" to exit
