Technical Documentation
Allows long distance control of the generator
(SUM/WIN
functioning, temperature adjustment and indication, programs and
parameters setting alarms display, reset, etc.)
and acts as weekly
chrono- thermostat.
If the Super CAR is installed the pre-existing X40 jumper must
be eliminated.
Using the Super CAR remote control it is possible to indifferently
vary some settings from the boiler control panel and from the Super
CAR remote control panel, such as: selection of Summer Winter,
DHW comfort status, DHW set point.

functioning
After 24 hours from the last activation, independently from the functioning status of the
boiler
(Summer or Winter)
, the pump (M1) is started for a time of 30 seconds and the
three-way valve (M30) is started for a period of 10 seconds.
After 24 hours of inactivity, the solar circuit pump (M6) is made to function for 10 seconds.

P.C.B. safety functions
If a fan speed is detected that is out of safe limits
(700-5700 rpm)
the burner is switched
off and it cannot be re-ignited for 7.5 minutes.
To re-start the appliance, press the “Reset”
button "C" and then make a central heating
or domestic hot water request.
Fan speed anomaly
In the case of: high resistance of the safety thermostat contact
(contact not perfectly closed or
worn);
anomaly on gas valve piloting circuit; no electric connection to the gas valve
(connector
disconnected or gas valve coils shut-off)
; error inside the integrated P.C.B, the latter performs
a reset and starts a new cycle to check contacts; if the problem persists after 6 check cycles,
boiler functioning is prevented.
To re-start the appliance, press the “Reset” button "C" and then make a central heating
or domestic hot water request.
Electro-mechanical
contacts block
In the case of dispersion of the detection circuit or anomaly in the flame control that
generates a correct ionisation current
(without the gas valve being open)
with the duration
of at least 20 seconds, boiler functioning is blocked.
To re-start the appliance, press the “Reset” button "C" and then make a central heating
or domestic hot water request.
Parasite flame block
If within 10 seconds from the start of the ignition cycle, the detection electrode (E2) has
not detected flame presence on the burner, boiler functioning is blocked.
The integrated P.C.B. makes 2 ignition attempts with duration of 10 seconds, intervalled
by a time of 30 seconds, after which it blocks.
To re-start the appliance, press the “Reset” button "C" and then make a central heating
or domestic hot water request.
N.B.:
It is possible to reset the anomaly up to 5 consecutive times, after which the function
is prevented for at least one hour and one attempt is gained after every hour. Five attempts
can be gained by by pressing the (IMG) or Stand-by key or by removing the power
supply to the circuit.
No ignition
block
The P.C.B. carries out a periodical self-check to control its correct functioning. During
functioning in heating mode or with boiler in stand-by, the function activates every 18
hours after the last boiler check/power supply.
In case of functioning in domestic hot water mode the self-check starts within 10 minutes
after the end of the withdrawing in progress, for duration of approx. 10 seconds.
N.B.:
the boiler remains inactive during the self-check, the display continues to show the
functioning state previous to the self-check, to then re-start normal functioning.
