ACCESS TO
INSTALLER'S
PARAMETERS
For access to the installer's parameters,
press simultaneously the keys
or 2 seconds (3 fig. 13).
For example, the parameter PAR 23 is
visualised on the display of the control
panel in the following way:
The paramet er s scr oll for war ds and
backwards with the key
the default parameters can be changed
with the keys
and
.
The standard visualisation returns automa-
tically after 60 seconds, or by pressing one
of the control keys (2 fig. 13) excluded the
key RESET.
3.5. 1
Replacing the board or
RESETTING parameters
If the electronic board is replaced or reset,
it is necessary to configure PAR 2 by asso-
ciating the following values to each type of
boiler to be able to restart the boiler:
BOILER
Double pump and
D.H.W. pressure
(HIGH INERTIA)
D.H.W. tank with diverter
valve and D.H.W. sensor
(HIGH INERTIA)
D.H.W. tank with double pump
and D.H.W. sensor
(HIGH INERTIA)
D.H.W. tank with
diverter valve and
D.H.W. thermostat
or heating only
(HIGH INERTIA)
D.H.W. tank with double pump
and D.H.W. thermostat
(HIGH INERTIA)
Heating only
and antifreese sensor
(HIGH INERTIA)
NOTE: the inside of the upper door of the
boiler panel has a label with the values
that have to be set for PAR 2 (fig. 16).
