In the heating phase, the electronic board
is programmed to include a burner tech-
nical delay interval of approx. 90 seconds,
which occurs both at system cold star-
ting and at subsequent re-ignitions. The
aim is to overcome the problem of repea-
ted ignitions and turning off with very
short time intervals between. This could

high head losses.
At each restart after the period of slow
ignition, the boiler will set itself for about
1 minute at the minimum modulation
pressure, and will then move to the hea-
ting pressure value set.
When the connecting link is inserted,
both the programmed technical pause
and the period of operation at minimum
pressure in the startup phase will be can-
celled. In this case, the times elapsing
