1st situation: ECO-STOP inactive (default)
If you de-activate this function, when the set temperature is reached,
the stove will continue operating at minimum power until power is
again requested by the thermostat or until the user decides to shut the
stove down manually.
The default setting for the stove is with ECO-STOP de-
activated as in the previous example.
2nd situation: ECO-STOP active and time-controlled
If this function is activated, when the set temperature is reached the
stove will go to minimum for a time set by the user, which may be from
1 minute to 30 minutes. During this time, if there is no temperature-
related request, the stove will then shut down automatically. The stove
will re-light automatically only if the thermostat requests heating.
Example with ECO-STOP active and time-controlled
If the room temperature measured by the thermostat probe (internal or
external) is 15°C and the temperature set on the thermostat is 20°C,
the stove will follow a pre-set ramp-up in power. Once the target
temperature is reached (20°C), the stove will go to minimum power.
The stove will remain in this mode for 15 minutes. If the room
temperature remains above the set temperature, the stove will
automatically shut down temporarily. The message “ Eco Stop” will be
shown. When room temperature drops below the thermostat set value
(for example 18°C) the stove will prepare for automatic relighting
(“COOL-FIRE”). It will then start operating until a temperature of 20°C
is once again reached.
If the stove is equipped with the kit for the production of domestic hot
water, and hot water is requested for over 30 seconds (by means of
the flow switch), the stove will relight immediately without going
through the aforementioned cooling phases (“COOL-FIRE”)
All automatic relighting operations, either due to a
drop in room temperature or a request for hot water,
are possible if the stove is on or in ECO-STOP mode.
If the user shuts the stove down manually with the
button
r, the stove will not relight automatically
upon variation of the temperature or if hot water is
requested
If there is a kit for the production of domestic hot
water, you should disable the ECO-STOP mode in
order to reduce response times when hot water is
requested.
It must be remembered however that the temperature keyed into the
thermostat is only indicative, and it is up to the user to find the correct
setting in the location where the stove is installed (for example, you
need to set 22°C on the thermostat to attain an actual temperature of
20°C). In this mode, the user can light the stove by resetting the
thermostat to a temperature greater than room temperature, or by
pressing for a few seconds on the button
r . You will go to "Off" mode,
and then the same button is pressed to relight the stove.
