Indication normal operation (continuous code)
Status Description
P De-aeration program: After restoration of
supply power, both the boiler pump and 3-way
valve are switched several times with the
purpose to move eventual air out of the boiler.
The de-aeration program lasts for 2 minutes.
During de-aeration time the burner is off.
O
No heat demand, stand-by
C
Central heating heat demand, burner off
C.
Central heating heat demand, burner on
c
Central heating pump post-running
d
DHW heat demand, burner off
d.
DHW heat demand, burner on
b
HWS heat demand, burner off
b.
HWS heat demand, burner on
o

o.
Frost protection 3°C (burner on, pump running)
Chimney sweeper function
Indication blocking mode (continuous code)
Status Description
6 Combi boiler sensor (internal tank) open
6. Combi boiler sensor (internal tank) shortcut
9 Flow or return sensor too high in temperature
A Flue gas temperature > 100°C
E No slave connected
J Central heating heat demand, anti-cycling timer
blocks burner for 3 minutes
P Water pressure too high or too low
2
Return temperature is 5°C above the flow
temperature blocks the burner.
Indication lock-out mode (flashing code)
Status Description
1
Boiler does not pass temperature test
(mostly by water problem or air bubbles)
2 Too many restarts during operation
5 Fan speed error
8 Flame detected with closed gas valve
9 Eeprom programmed
A
Flue gas temperature > 100°C
(for more then 3 times within 30 minutes)
E Internal regulation fault / A/D conversion fault
E - t1 Flow sensor (open or shortcut fault)
E - t2 Return sensor (open or shortcut fault)
E - t3 Flue gas sensor (open or shortcut fault)
E Internal regulation fault / A/D conversion fault
F Too much (4) consecutive start attempts
H Flow or return sensor temperature > 105°C
Customer may use the Set/Reset button, however,
with repeating failures in short period of time always let
your installer or maintenance man check and repair
unconditionally.
Some lock-out situations can only be removed by power
restoration.
View mode
In the view mode some actual boiler values can be read.
Press the (+) button for at least 10 seconds and the view
mode will come up. The first indication is the water
pressure status P /u. On the 3 right displays read the
actual water pressure in bar.
Press the Set/Reset button once for next parameter.
When the display keys are untouched for 3 minutes, by
time-out the system will switch back to the normal status
indication.
Manual return is by pressing the (-) button once.
View mode Stand-alone boiler
Status Description
P / u actual water pressure (in bar)
] / u setpoint on flow sensor (in °C) (default)
] / u
With parameter C/r = 1 the setpoint is
switched to the return sensor or optional
system sensor.

2 / u actual return temperature (in °C)
3 / u 0÷10V control (in Volt)
4 / u outdoor temperature (in °C)
5 / u
Combi-boiler internal tank or external storage
cylinder temperature (in °C)
6 / u flue gas sensor temperature (in °C)
7 / u flame signal (in µA DC)
9 / u Last lock-out
A / u Last blocking
d / u
actual system sensor temperature (in °C)
(parameter C/r=1)
Menu mode
The menu mode is for making adjustments to the boiler,
and is intended for use by installer or maintenance man.
Press the Set/Reset button for at least 10 seconds and
the menu mode will open with h=10.
