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 2/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 2/sub menu 2/
parameter 0.
Heating ignition delay adjustment
This parameter – menu 2/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 2/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.
