bol disappears.
DHW mode operation
This symbol is present if there is
a DHW drawing.
Lockout symbol
The function of this symbol is to
indicate the burner safety inter-
vention, due to:
— lack of gas
— not detected ignition
In the first case, no ignition oc-
curs: verify that the gas feeding
is present.
In the second case, check the
ignition electrode and the con-
nections to the main PCB.

the maximum (or minimum)
capacity, in order to allow the
gas valve adjustment and the
smoke analysis.
When this function is activated,
by pushing this button once, the
boiler will operate at maximum
capacity. The radiator symbol will
be blinking, while the flame
symbol will be permanently
lighted.
