automatically selected according to the water boiler temperature and the value of Boiler Thermostat Th24:
* Boiler water temperature ≤Th24–D08
the system goes to the maximum available power
* Th24–D08<boiler water temperature<Th24
the combustion power is chosen proportionally (the greater is
the difference between the water temperature and the thermostat Th24, higher will be the chosen power.
* boiler water temperature≥Th24
the system goes to Power 1 or, if enabled, at Modulation Power
The parameter d08 must be a multiple of the number of operating powers minus one.
Factory adjusted: A06=1, Modality=[A], Thermostat Boiler Th24=60 °C, Delta D08=6 °C, P03=6

Optionally heating fan can be switched Automatically, OFF or adjusted manually from speed 1 (min) to
speed 6 (max) from control panel (see User Menu 2). Our suggestion is users to choice “Auto”. On this mode
factory adjustment for parameter
P06
is “2”. The heating fan is working proportional to the exhaust tempe‐
rature. If some user prefers different Automatically adjustment can use next procedure with following
functioning:
If the user chooses the automatic mode of heating, the system selects the power. By setting the parameter
P06
in the Default Settings, it is possible to manage the heating power:
P06=1 (Same as Combustion Power)
The Heating power is the same as Combustion power.
P06=2 (Proportional to exhaust temperature)
The system selects the heating power according to the value of exhaust temperature, of
Th05
Thermostat
and of parameter
D04
(
D04
has to be a multiple of the powers’ number less one).
