5A LIGHT SIGNALS AND FAULTS
The control panel has two led that indicate the boiler operating status:
Green led
Flashing
- Flashing with frequency 0.5 second on - 3.5 seconds off = boiler in standby,
there is no flame.
- Flashing with frequency 0.5 second on - 0.5 second off = temporary stop
of the appliance due to the following self-restoring faults:
- water pressure switch (standby time 10 minutes approximately)
- air pressure switch (standby time 10 minutes approximately)
- transitory waiting for ignition.
In this phase, the boiler waits for restoration of working conditions. If after
standby time, the boiler will not restore regular operation, stop will be
permanent and light signalling will be red.
- Fast flashing (frequency 0.1 sec. on; 0.1 sec. off; duration 0.5) input/output
function CTR (Environment Automatic Adjustment System).
By setting the heating water temperature selector in the zone marked
by symbols in bold type - temperature value from 55 to 65 °C - the CTR
self-adjusting system is activated: the boiler varies the delivery tempera-
ture according to the closing signal of the ambient thermostat. When the
temperature set with the heating water temperature selector is reached, a
20 minutes count begins. If during this period the ambient thermostat still
requests heat, the value of the set temperature automatically increases by
5 °C. When the new value is reached, other 20 minutes count begins.
If during this period the ambient thermostat still requests heat, the value
of the set temperature automatically increases by 5 °C.
This new temperature value is the result of the temperature set manually
with the heating water temperature selector and the increase of +10 °C
of the CTR function. After the second increasing cycle, the temperature
value is restored to the value set by the user and the above mentioned
cycle is repeated until the ambient thermostat request is fulfilled.
Fixed green
if there is flame, the boiler works regularly.

Red led
If the red LED lights up, this indicates the presence of a fault; the monitor
visualises a code interpreted as follows:
A 01 flame failure (fixed red LED + flame failure icon
A 02 limit thermostat intervention (blinking red LED)
A 03 air pressure switch intervention (fixed red LED)
A 04 water pressure switch after the transitory phase (fixed red LED + fixed
green LED + filling icon )
A 06 domestic hot water NTC probe (blinking green + red LEDs)
A 07 heating NTC probe (fixed red LED)
To restore operation: faults A 01-02-03
Position the function selector on
to the required position. If the reset attempts do not reactivate the boiler,
contact the Technical Assistance Centre.
Fault A 04
Along with the fault code, the digital monitor visualises the
Check the pressure value indicated by the hydrometer: if it is less than 0.3
bar, position the function selector on
the pressure reaches a value between 1 and 1.5 bar. Position the function
selector on the required position. If these pressure drops occur frequently,
contact the Technical Assistance Centre.
Fault A 06
The boiler functions normally but does not guarantee a constant domestic
hot water temperature, which remains set at around 50°C.
Fault A 07
Contact the Technical Assistance Centre.
Fixed yellow LED
Pre-heating function activated.
When the LEDs flash alternatively it means that there is a calibration
procedure in progress.
OFF, wait 5-6 seconds then rotate it
OFF and adjust the filling tap until
