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 potentio-
meter 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 successive
re-ignition for the same request.

Safety devices.

When 24 hours have passed from the last activation, independently from the functioning
state of the boiler (Summer or Winter), the pump (M1) is started for 30 seconds.
When 24 hours have passed from the last activation, independently from the functioning
state of the boiler (Summer or Winter), the 3-way valve (M30) is started 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
of the safety device is signalled on the boiler control panel display with the error code 01.
To restore appliance functioning, turn the main switch (S2) to the Reset position.
