AND WATER PRESSURE
TRANSDUCER
Antifreeze system made up of the NTC hea-
ting sensor that activates when the water
temperature reaches 6°C. Tables 1 – 1/a
include the resistance values (Ω) that are
obtained on the valve when the temperatu-
re changes and those on the
transducer when pressure changes.
The module does not work when the hea-
ting probe (SM) is cut off.

3.3 ELECTRONIC IGNITION
Flame detection ignition is controlled by two
electrodes that guarantee maximum safety
with intervention time, for accidental shut-
downs or no gas, within 1 second.

Operating cycle

Rotate the selector to summer or winter
and check the green led (
power is on. The burner should ignite within
max. 10 seconds. Failed ignition consequen-
tly lighting the appliance block signal may
occur due to the following:
– Ignition electrode does not spark
Only gas is supplied to the boiler and,
after 10 sec., the block led turns on.
It may be caused by the fact that the elec-
trode is cut-off or is not secured in the
ignition transformer terminal.
– No flame detection
At ignition, the electrode continues to
spark even though the burner is on. After
max.
10 sec. it stops sparking, the burner
320
turns off and the block led turns on.

AIR PRESSURE

SWITCH
The pressure switch signal value is measu-
red by a specific tool connected to the posi-
tive and negative pressure fixtures.
The pressure switch is factory set to 35-
) to make sure 45 Pa.
3.5 AREA SYSTEM
ELECTRICAL
CONNECTIONS
For the "DEWY EQUIPE P100 BOX" heat
module use a separate electrical line where
the room thermostats with relevant area
valves or pumps must be connected.
Switch or relay contacts must be connec-
ted to the electronic board connector (J2)
after removing the existent bridge (fig. 17).
