Adjustments.
With the SUM/WIN selector switch in the WINTER position, it
allows the pump to function continuously or only on request of
the room thermostat.
In the DHW mode with the selector switch present. the burner
switches off at 65 °C (fixed), With the selector switch absent the
burner switches off at the set temperature +5 °C (solar function).
N.B.: for models with storage (Storage tank unit), the presence or
not of the jumper does not affect boiler functioning.
Depending on the position, it allows the central heating potenti-
ometer to adjust the temperature from 25 °C to 85 °C (range 1) or
from 25 °C to 50 °C (range 2).
At every switch-off due to the temperature being reached in CH
mode a delay of 3 minutes/30 seconds is inserted until the succes-
sive re-ignition for the same request.

Safety devices.

The pump (M1) is made to function for 30 seconds after:
- 24 hours of inactivity with the main selector switch in SUMMER position.
- 3 hours of inactivity with the main selector switch in WINTER position.
After 24 hours from the last activation, independently from the boiler functioning status
(Summer or Winter), the 3-way valve (M30) is made to function for 10 seconds.
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 intervention is signalled with the relative flashing of an error on the boiler control
panel.The main selector switch (S2) must be turned to the Reset position in order to
restore functioning of the appliance.
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.
The main selector switch (S2) must be turned to the Reset position in order to restore
functioning of the appliance.
