12-MENU ENTRIES AND OPERATION
AUTO ECO MODE
The Auto-Eco mode changes the behaviour of the boiler in automatic mode, that is:
when the ambient temperature set by the user is reached (the temperature is detected by the probe on the equipment or by the external
thermostat), the boiler modulates at power value 1 for a short period of time; if the temperature remains constant or is higher than the set
temperature the boiler turns off, while if the room becomes cold and there is a demand for heat the boiler turns on again automatically
(not before a time interval required for the boiler to cool down).
This mode is recommended only if the product operates in highly insulated areas or where there is minimal heat loss over time as it allows
you to optimise the boiler’s consumption without wasting fuel.
For activation of the ‘’Auto Eco’’ mode and time settings, see sections “f” and “g”.
The ECO stop procedure is activated automatically when all the power recall devices included in the “system configuration” are satisfied:
room temperature probe/external thermostat (configurations 1-2-3), flow switch (configuration 2), thermostat/ntc (10 kΩß3435) puffer
(configuration 4-5) or thermostat/ntc (10 kΩ ß3435) boiler (configuration 2-3). If all the devices present are satisfied, the time begins
to decrease “T ECO stop” (10 minutes default, can be changed in the “Settings” menu). During this phase, the panel alternates between
displaying ON with a small flame and Crono (if active) - Eco active. The minutes counting down to the Eco Stop are shown at the top of the
display. The flame moves to P1 and remains there until the set “T Eco Stop” time reaches zero, and if the conditions are still satisfied, turns
off the boiler. The ECO stop count is cancelled if one of the devices recalls power.
When the boiler begins to turn off, the panel shows: Off - Eco Active - flashing small flame.
When the boiler turns off, OFF-ECO appears on the display with the flame symbol off.
The following conditions have to be met simultaneously for the ECO to restart:
• Power recall
• external thermostat contact closed
• Room temperature < Room Setpoint Value -2°C
• 5 minutes have passed since shut-down.
• TH

O < TSetH

• If the power is recalled by the domestic hot water (DHW), the 5’ are ignored and the boiler starts up as required.
NOTE: In configuration 4 - 5 the Auto Eco mode is enabled automatically. Also when in configuration 2 - 3, with the ‘summer’ function set,
it is enabled automatically. Where it is prescribed that it should be enabled, the mode cannot be disabled.
h - Pump T On (only for experienced users)
This option enables adjustment of the pump activation temperature.
Use key 5 to go to the settings menu and select the Pump T On option. Confirm with key 5 and then with keys “b” (arrows) you can increase
or reduce the temperature. Key 5 is used to confirm, while key 8 is used to go back to the main screen.
