Description
Activates bleeding the system's air. To activate air
bleeding, it is necessary to switch on the boiler
and change the parameter from "No" to "Yes".
Wait for one minute. Switch off and restart. At this
stage, when it is restarted the boiler will initiate
the automatic bleeding procedure (lasting around
20 minutes). With the parameter set to "Yes", the
procedure is carried out each time the boiler is
switched off and restarted using its master switch.
The value must be set to "No" if you do not wish to
initiate the bleeding procedure when the boiler is
switched on.
Defines the flow rate below which the boiler is
switched off. The value varies depending on the
model.
Sets the weekday on which the anti-Legionella
procedure is carried out.
Sets the time of the day during which the anti-Le-
gionella procedure is carried out.
Activates the emergency mode. This mode comes
on when communication between Managing and
the primary circuit's sensor is lost. In this event, if
Par. 72 is set to "Yes", the cascade is initiated, work-
ing to the fixed set-point determined by Par. 74.
Set-point active in emergency mode.
Defines the stand-by time in seconds to restart the
subsequent cascade boiler in normal start mode.
Defines the stand-by time in seconds to switch off
the last cascade boiler on in normal Off mode.
Defines the stand-by time in seconds to restart the
next cascade boiler in quick start mode.
Defines the stand-by time in seconds to switch off
the last cascade boiler on in Quick Stop mode.
Defines how many degrees the temperature mea-
sured by the primary circuit's sensor must fall below
the set-point in order for the subsequent boiler to
be started after the time interval set by Par. 75.
Defines by how many degrees the temperature
measured by the primary circuit's sensor must go
above the set-point in order for the subsequent
module to be switched off after the time interval
set by Par. 76.
Defines how many degrees the temperature mea-
sured by the primary circuit's sensor must go below
the set-point in order for the subsequent boiler
to be started after the time interval set by Par. 142
(quick-start mode).
