Number of de-aeration cycles
Each cycle includes two ON/OFF sequences, each having 10
seconds ON and 10 seconds OFF.
Factory setting anticipates 2 de-aeration cycles every time
that the de-aeration function comes on.
1st cycle: the boiler’s 3-way diverter valve moves to the
central heating position and the boiler pump comes on
for 10 seconds, goes off for 10 seconds, comes back on for
10 seconds and then goes off again for 10 seconds. This
cycle lasts 40 seconds.
2nd cycle: begins at the end of the 1st cycle. The 3-way
diverter valve moves to the DHW position and the pump
repeats the same ON/OFF procedures as above, for a total
of 40 seconds.

Number of repetitions of de-aeration cycles
This parameter sets the number of repetitions for each
de-aeration cycle set in Par. 2091.
The sequence of de-aeration cycles is carried out for the
number of times set in this parameter.
Based on the factory settings of parameters 2091= 2 and
2092= 10, the total duration of the de-aeration function is
800 seconds (2 cycles of 40 sec. 10 times).
