Dair active
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 thermal
module is switched on.

Frost Pro-
tection
Defines the delivery temperature below which the
thermal unit pump and the system pump (with
cascade configuration) are activated if. If the tem-
perature of one of the delivery sensors (excluding
the zone sensors) falls another 5 degrees below
the value set by Par. 155, then a request to activate
the cascade is generated. When the temperature of
the primary sensor reaches five degrees above the
value defined by Par. 155, then the request ceases
and the cascade returns to stand-by mode.

Activates the emergency mode. This mode comes

if Par. 72 is set to "Yes", the cascade is initiated,
