QUADRA GREEN C.S.I.

To restore operation (deactivate alarms):
Faults A01-02-03

Position the function selector to

(OFF) (ﬁ g. 32), 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 As-
sistance Centre.

Fault A04

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) (ﬁ g. 32) and adjust the ﬁ lling
tap until the pressure reaches a value between 1 and 1.5 bar. Then position
the mode selector to the desired position

(summer) or

(winter).

The boiler will perform one purge cycle lasting approximately 2 minutes. If
pressure drops are frequent, request the intervention of the Technical As-
sistance Service.

Fault A06

The boiler operates normally but cannot reliably maintain a constant do-
mestic hot water temperature, which remains set at around 50°C. Contact
the Technical Assistance Centre.

Fault A07

A08

Contact the Technical Assistance Centre.

Fault A09 with ﬁ xed red LED lit

Position the function selector to

(OFF) (ﬁ g. 32), 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, request the intervention of the Techni-
cal Assistance Service.

Fault A09 with ﬂ ashing red and green LEDs

The boiler is equipped with an auto-diagnostic system which, based on the
total number of hours in certain operating conditions, can signal the need
to clean the primary exchanger (alarm code 09 with ﬂ ashing red and green
LEDs and ﬂ ue gas meter >2.500). Once the cleaning operation has been
completed, using the special kit supplied as an accessory, the total hour
meter will need to be reset to zero as follows:

-  switch oﬀ  the power supply
-  remove the housing
-  loosen the ﬁ xing screw then turn the instrument panel
-  loosen the ﬁ xing screws on the cover (

) to access the terminal board

(ﬁ g. 16)

- while the boiler is powered up, using a small screwdriver included, press

the

button (ﬁ g. 26) for at least 4 seconds, to check the meter has

been reset, power down then power up the boiler; the meter reading is
shown on the monitor after the “-C-” sign.

Live electrical parts.

NOTE:

the meter resetting procedure should be carried out after each

in-depth cleaning of the primary exchanger or if this latter is replaced. To
check the status of the total hour meter, multiply the reading by 100 (e.g.
reading of 18 = 1800 total hours; reading of 1 = 100 total hours).
The boiler continues to operate normally even when the alarm is activated.

Fault A77

This is an automatic-reset fault, if the boiler does not restart, contact the
Technical Assistance Centre.

Fixed yellow LED

Pre-heating function activated.

Flashing yellow LED

Combustion analysis in progress.

4.4 Alarm records

The “ALARM RECORDS” function starts automatically once the display has
been on for 2 hours, or immediately by setting the P1 parameter to 1.
The records include all the latest alarms, up to a maximum of 5 alarms, and
they are displayed in sequence by pushing and releasing the P1 button on
the display board. If the records are empty (P0=0) or if tracking the same is
disabled (P1=0), the display function is not available. Alarms are displayed
in reverse order compared to the order in which they occurred: this means
that the last alarm generated is the ﬁ rst to be displayed.
