Brief description of the automatic firing
device
The automatic firing device BIC 960 of the UltraGas
®
only works in connection with the heating regulator
TopTronic
®
E/UG. As a result, the automatic firing device
only has to take over the last missing functions for correct
operation of a modulating gas boiler.
These are some properties that are integrated in the au-
tomatic firing device:
• PWM control of the blower (230 VAC)
• Modulating operation
•
Common electrode for ignition and flame monitoring
(ionisation)
• LPG valve or boilerhouse fan can be activated
• Inputs for:
- Flow sensor 1
- Flow sensor 2
- Flue gas sensor
- Water pressure sensor
- Safety - limit value thermostat (not used)
- Air pressure switch
- Gas pressure switch
• «Fault» and «Flame message» status outputs
• Additional (external) ignition device can be connected
• RS 485 connection to TopTronic
®
E/UG
• RS 232 connection to the PC
• Number of start attempts: maximum 4
• Safety time: 5 sec
• Pre-ignition: 5 sec
• Pre-ventilation period: 50 sec
• Follow-on time for pump (230 VAC): 5 min after a heat
demand
Fuses:
There are 3 fusible links on the BIC 960:
- 2 A slow-blow
Mains
- 4 A slow-blow
Pump
- 4 A slow-blow
Burner blower
If one of the two 4 A slow-blow fuses, each of which pro-
tects either the pump or burner blower, blows, the device
in question will not start operating.
Failure of the mains fuse of the automatic firing device is
indicated on the display of the TopTronic
®
E/UG by the
"B:30 Bus interruption to automatic device" error mes-
sage.

Data related to NCV.
The boiler series is tested for EE/H-settings. With a factory setting of the Wobbe coefficient
of 15.0 kWh/m
3
operation at a Wobbe coefficient of 12.0 up to 15.7 kWh/m
3
is possible without new settings.
