COMMISSIONING
The table indicate the existing relationship between the gas
pressure at the burner and the boiler power level in heating
mode.
Maximun 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” and 0 of this interval.
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 Pressure table.
Checking slow ignition power
The soft light can be adjusted between the maximum power and
the minimum power.
The display shows the value between “100” and 0 of this interval.
To check the slow ignition power, access menu 2/sub menu 2/
parameter 0.
If needed, change the parameter value until suitable pressure is
achieved.
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.
By selecting manual, 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.
