Primary circuit temp. limit during D.h.w. op-
eration.
Boiler Stand-By, hyphens are turned on in
sequence to simulate running (antifreeze
protection activated).
lcd functiOn
In the case of incorrect pressure the value is
visualised with a flashing symbol.
When pressure is achieved the symbol re-
mains on for 15 s and then disappears.
Flashing:
high pressure > 2.8 bar ON, 2.6 bar OFF;
intermediate pressure
0.15 < P < Pon rising
0.15 < P < (Pon-0.2) decreasing;
pressure critical
0.00 < P < 0.15 bar.
Pump activated for the post-circulation
phase (Po fl temperature flashing).
Boiler in anti-freeze phase (bP flashing +
temperature flashing).
Boiler on demand for d.h.w. power.
The d.h.w. temperature is displayed.
Boiler requesting heating power and remote
control connected.
Set c.h.
(all other symbols are disabled).
Set D.h.w.
(all other symbols are disabled).
Delayed burner ignition for setting the sys-
tem (the hourglass symbol turns on).
Boiler in chimney sweep in function.
The activation of the chimney sweep occurs
configuring the "parameter P09=01" and is
visualized:
LP = minimum d.h.w.;
hP = minimum heating;
cP = maximum heating;
dP = maximum d.h.w.;
The transition occurs with keys A (increase)
and B (decrease) d.h.w. temperature.
The writing on the display alternates.
