10-OPERATION
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.
•
TH
O < TSetH
O.
2
2
•
If the domestic hot water (DHW) demands power 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 is not possible to deactivate the mode.
SLEEP FUNCTION (main menu)
The sleep function is activated only when the boiler is switched on and allows to quickly set a time at which the product must switch off.
To set the Sleep function act as follows:
•
Enter MENU
•
Scroll to SLEEP with the <> arrows
•
Press Menu
•
With the + - keys adjust the desired shutdown time.
The panel proposes a shutdown time of 10 minutes from the current time, adjustable with key 4 until the next day (I can therefore delay
the shutdown for up to a maximum of 23 hours and 50 minutes).
If the SLEEP function is active with the TIMER active the first has priority over the latter, therefore the boiler will not switch off at the time
set on the timer but instead by the time established by the sleep function, even if later than the time set on the timer.
