NOTE
TECHNICAL DATA
Supply voltage:
220/240V @ 50/60Hz
On request: 110/120V @ 50/60Hz
Operatine temperature range:
-20°C ÷ +60°C
Ambient humidity:
95% MAX @ 40°C
Protection degree:
IP 00
Times:
- prepurge or waiting time (TW):
1.5 … 40 s
- safety time (TS):
3 ... 120 s
- response time on running flame failure (TR):
< 1 s
The times given on the burner control label correspond to the
values guaranteed. The actual values slightly differ from the values
given, pre-purge and waiting time is in fact longer and safety time
shorter than their nominal values.
Power consumption, at starting up:
types without burner 10VA
types with burner 12VA
Power consumption, running:
types without burner 7VA
types with burner 9VA
Contact rating:
- Thermostat:
4A cosϕ ≥ 0.4
- VG1:
0.5A cosϕ ≥ 0.4
- VG2:
0.5A cosϕ ≥ 0.4
- Fan motor:
1A cosϕ ≥ 0.4
- Lock-out signalling:
1A cosϕ = 1
- Auxiliary contact:
0.5A cosϕ ≥ 0.4
Max. length of the cables of external components:
1 m
Internal fuse rating:
4A fast
External fuse rating:
3.15A fast
Flame control:
The ionization flame detection device makes use of the
rectification property of the flame.
The ionization flame detector device is not a safe to touch
output (no provision with protective impedances).
- Minimum ionization current:
0.5µA
on request:
1.2µA / 2.5µA
- Max ionization current @ 230V:
8.5µA DC
- Recommended ionization current:
3÷5 times the
minimum value
- Max. length of the cable: 1 m
- Minimum insulation resistance of the
cable and the flame
detector device to earth:
≥ 50 MΩ
- Max. parasitic capacitance of the
detection probe:
≤ 1 nF
- Max. short circuit current:
< 200µA AC

This contact is not isolated from the main supply voltage by
reinforced isolation, therefore the relay contact is not suitable to
supply SELV circuits – Safety Extra Low Voltage.

Safety thermostat opening causes cycle repetition and
volatile/non-volatile lockout.

Standard connectors are Stelvio-Stocko models, as shown in
Fig.2.

Device is compliant only if the note “EN 298:2003 compliant”
and the option “#” are report on the label.
