Short description of the automatic function
device
The BIC 960 automatic function device of the UltraGas
®
only works in conjunction with the TopTronic
®
E/UG hea-
ting controller. The automatic function device takes over
the functions for correct operation of a modulating gas
boiler.
These are some properties that are integrated in the au-
tomatic function device:
•
PWM control of the fan (230 VAC)
•
Modulating operation
•
Common electrode for ignition and flame monitoring
(ionisation)
• LPG valve or boiler room fan can be activated
• Inputs for:
- Flow sensor 1
- Flow sensor 2
- Exhaust 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 fan
If one of the two 4 A slow-blow fuses, each of which pro-
tects either the pump or burner fan, blows, the device in
question will not start operating.
Failure of the mains fuse of the automatic function device
is indicated on the display of the TopTronic
®
E/UG with
the “B:30 bus interruption to automatic device” error mes-
sage. With double boiler or cascade systems, the next
heat generator is automatically activated in this case.
