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.
