Short description of the functions of the BIC 960 automatic firing device
Since the automatic firing device can only perform in connection with the heating controller, many common functions
are already given via this. The list below contains only those characteristics which are integrated in the automatic
firing device:
- Modulating operating mode
- Combined electrode for ignition and flame monitoring (Ionisation)
- Main gas valve (possibly LPG-valve) and/or heating room fan acitvatable
- Inputs for Flow sensor 1
Flow sensor 2
Flue gas sensor
Water pressure sensor
Safety and limit value thermostat (external exhaust gas temperature switch possible)
Air pressure switch (not used)
Gas pressure switch
- “Alarm” and “Flame monitoring” status outputs
- Additional (external) ignition can be attached
- RS 485- connection to heating controller
- RS 232-connection to PC
- Number of start-up attempts: maximum 4
- Safety time: 5 secs
- Pre-ignition: 5 secs
- Pre-venting: 50 secs
- Pump after-run time (230V AC): 5 min after heating demand
Faults:
If there is a fault, an error code will appear on the display of the heating controller. Pressing the reset button, located
under the hinged cover on the front of the unit, will release the automatic burner, and the boiler will resume opera-
tion, if the fault has been rectified. For more detailed information, see section 7.
Fuses:
The BIC 960 has 3 safety fuses:
2AT
Mains
4AT
Pump
4AT
Burner fan
What happens when the fuses blow
4AT (Pump)
Pump fails to start.
4AT (Burner fan)
Burner fan fails to start. If a rotation set value has been allocated for the burner fan,
an error message E:18 (“Fan rotation speed below limit”) will appear after a short
period of time, indicating that the fuse has blown.
2AT (Mains)
there is no communication between the automatic firing unit and the heating control-
ler. As a result an error message is displayed on the heating controller.
