4.3 Switching off
Temporary switching off
In case of absence for short periods of time, set the mode selector
(3-g.1a)to
(OFF).
Inthisway(leavingtheelectricityandfuelsuppliesenabled),the
boilerisprotectedbythefollowingsystems:
- Anti-frost device: when the temperature of the water in the boiler
fallsbelow5°C,thecirculatorand,ifnecessary,theburnerare
activated at minimum output levels to bring the water tempera-
turebacktothevaluesforsafety (35°C). During the anti-frost
cycle,thesymbol
appears on the digital monitor.
-Circulatoranti-blockingfunction:anoperationcycleisactivated
every24hours.
Long period switching off
In case of absence for long periods of time, set the mode selector
(3-g.1a)to
(OFF).
Then,closethegastappresentonthesystem.Inthiscase,anti-frost
deviceisdeactivated:emptythesystems,incaseofriskoffrost.

Position the function selector to
(OFF),wait5-6secondsthen
set it to the required position
(summermode)or (winter
mode).Iftheresetattemptsdonotreactivatetheboiler,contactthe
Technical Assistance Centre.
Fault A 04
Inadditiontothefaultcode,thedigitaldisplayshowsthesymbol
.
Checkthepressurevalueindicatedbythewatergauge:
if it is less than 0.3 bar, position the function selector to
(OFF)
andadjust the lling tap (Lg.13)until the pressure reaches a
value between 1 and 1.5 bar.
Then position the mode selector to the desired position
(sum-
mer)or
(winter).
If pressure drops are frequent, request the intervention of the Tech-
nical Assistance Service.
Fault A 06
Theboileroperatesnormally butcannotreliably maintainacon-
stant domestic hot water temperature, which remains set at around
50°C. Contact the Technical Assistance Centre.
Fault A 07
Contact the Technical Assistance Centre.
4.5 Adjustments
Theboilerhasalreadybeenadjustedbythemanufacturer.
Ifitisnecessarytoadjustitagain,forexampleafterextraordinary
maintenance, after replacement of gas valve or after gas conver-
sion,carryoutthefollowingprocedure.
The maximum output adjustment must be carried out in the
sequenceindicatedexclusivelybyqualiedpersonnel.
- removetheshellunscrewingthexingscrewsA(g.6)
- unscrewbytwoturnsthescrewofthepressuretestpointdown-
stream the gas valve and connecting the pressure gauge
- disconnect the compensation inlet of the air distribution box
(onlyC.S.I.model)
4.5.1 Maximum power and minimum domestic hot wa-
ter adjustment
- Fullyopenthehotwatertap
- on the control panel:
- set the mode selector to
(summer)(g.2a)
- turn the domestic hot water temperature selector to its maximum
(g.7a)
- powertheboilersettingthesystemmainswitchto“on”
- check that the pressure on the pressure gauge is stable; or with
a milliammeter in series to the modulator, make sure that the
modulatorsuppliesthemaximumavailablecurrent(120mAfor
G20and165mAforLPG).
- carefullypriseouttheprotectioncapoftheadjustmentscrews,
usingascrewdriver(g.15)
- with a fork spanner CH10 use the adjustment nut of the maxi-
mum output in order to obtain the value indicated in table "Tech-
nical data"
- disconnect the modulator faston
- wait until the pressure on the pressure gauge is stable at mini-
mum value
- paying attention not to press the internal shaft, use anAllen
spanner to turn the red adjustment screw for domestic hot water
minimum temperature regulation, calibrating it until the pressure
gauge reads the value indicated in the table "Technical data"
- reconnect the modulator faston
- close the domestic hot water tap
- carefullyrettheprotectioncapoftheadjustmentscrews.
4.5.2 Minimum and maximum heating electric adjust-
ment
 The “electric adjustment” function is activated and deacti-
vatedexclusivelybythejumper(JP1)(g.16).
ADJ
appearsonthedisplaytoindicatethatthecalibrationpro-
cedureisunderway.
Thefunctioncanbeenabledinthefollowingway:
- bypoweringthecardwiththejumperJP1insertedandthemode
selectorinwinterposition,independentlyfromthepossiblepres-
ence of other operation request.
- byinsertingthejumperJP1,with the mode selector in winter
position, without heat request in progress.
 Byactivatingthefunctiontheburnerisignitedthroughsimu-
lation of heat request in heating.
To perform calibration operations, proceed as follow:
- switch off the boiler
- remove the shell and access the card
-insertthejumperJP1(g.16)toenabletheknobsplacedonthe
control panel to the minimum and maximum heating adjustment
functions.
- makesurethatthemodeselectorisinwinterposition(seesec-
tion4.2).
- power the boiler
Electric card in voltage (230 Volt)
-turntheheatingwatertemperatureadjustmentknobB(g.17)
until it reaches the minimum heating value as indicated in the
multigas table
