Maximum Heating Power adjustment
The maximum heating power can be adjusted to
between the maximum power allowed by the boiler
and the minimum power.
The display shows the value between 100% ("99" on
the display) and 0% ("0").
To check the maximum heating power, access
menu /sub menu 3/parameter 1, check the value
and, if necessary, modify it as indicated in the Gas
Regulation table. (below).
Checking slow ignition power
The soft light can be adjusted between the maximum
power (shown on the display as "99", i.e. 100%) and
the minimum power (shown on the display as "1", i.e.
1%).
To check the slow ignition power, access menu /sub
menu /parameter 0.
Heating ignition delay adjustment
This parameter – menu /sub menu 3/parameter 5
- can be used to manually (0) or automatically (1) set
the delay time before the subsequent reignition of
the burner after it has switched off on reaching the
desired temperature in central heating mode.
By selecting manual (0), it is possible to set the delay
in minutes using the successive parameter (menu /
sub menu 3/parameter 6), to a time between 0 and
7 minutes.
Automatic selection means that the boiler will
establish the delay time based on the set-point
temperature.
