2. Description of functions

2.1 GeneralThe BIC 960 automatic firing device is designed for use in a modulating gas boiler. There for a PWM fan is triggered by the automatic firing device. This fan has a supply voltage of 230V which is shut-off by an internal relay during downtimes in order to reduce stand-by losses. Fan revolution speed modulation is controlled via an internal PID con-troller in order to maintain the desired flow temperature. The flow reference value is not determined in the automatic firing device, but is calculated and passed on via the heating controller. The BIC 960 automatic firing device can only be used in connection with the TopTronicT/UG heating controller, why the BIC 960 is installed in the background, i.e. the circuit board is not visible from the outside, and complete opera-tion is controlled via the heating controller. The result is a unique principle of operation at boiler level via one inter-face.

2.2 Water heater-ChargingSwitch-over between hot water charging and heating demand is controlled by the TopTronic®T/UG.

2.3 emission measuring and/or test function for gas valve settingThere is a specific key on the heating control unit allocated for emission measurements and/or gas valve adjustment. By using the emission key, a mode of operation is initiated in which the automatic firing device operates in heating mode, with an assigned reference value of 80°C, and in which power output can be adjusted manually using the rotary button. After 20 minutes emission testing operation is ended automatically, and the boiler reverts to the prior operation mode. It is important to ensure that the heat produced during emission testing can also be discharged. When setting boiler performance in terms of percentage values, ensure that 1% is the set minimum performance and 100% is the set maximum performance. In between, there is a linear relationship, on which is it possible to set the desired boiler performance.

2.4 Main switchThe main switch is located on the front of the heating control unit. It takes care for the power supply of the heating control unit and of the automatic firing device, located in the background. When the switch is turned off, frost protec-tion is not active.

2.5 Main gas valve (possibly lPG-valve) / heating room fanAn external main gas valve (possibly a fluid gas valve) and/or a heating room fan can be controlled by the auto-matic firing device. The output is activated a set time (depending on the parameter settings) before activation of the burner start. This application requires a suitable parameterisation of the automatic firing device. Ensure that the TopTronic®T/UG display shows the blocking B:04 (main gas valve) possibly LPG-valve)/ heating room fan) during the burner start delay. Blocking is no longer shown beginning with BIC 960 V.3, but the waiting time has been retained.

2.6 external burner switchLocking or activation of the automatic firing device takes place via the TopTronic®T/UG. The parameters must be set to allow a suitable variable input, as described in the Customer-service technicians introduction to the TopTronic®T/UG.A further possibility is provided by blocking input X9-1/X9-4 via which the automatic firing unit can be set to blocked status. In this case no error message is displayed at the TopTronic®T/UG.

2.7 short description of the functions of the BIC 960 automatic firing deviceSince the automatic firing device can only perform in connection with the TopTronic®T/UG 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 TopTronic®T/UG- 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, a flashing error code will appear on the display of the TopTronic®T/UG alternating with the normal display information. 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 operation, 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 fanWhat 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 TopTronic®T/UG. As a result the error message “DATABUS ERROR 70-6” is displayed on the TopTronic®T/UG.

2.8 Access to the automatic firing deviceThe boiler is operated in the same way as described in the operating instructions of the TopTronic®T/UG. The auto-matic firing device operating in the background can be accessed using a special menu tree on the TopTronic®T/UG. This menu allows access to the “BOILER CONTR” submenu, where it is possible to view an information level and a parameter level. „INFORMATION“: As well as actual system values, which can be displayed via the Info-key, this option also al-

lows specific state variables to be viewed. (for further information see “Display of Information from the Automatic Firing Device”)„PARAMETER“: Depending on the user level, which can be reached using various code levels, it is possible to

amend certain parameters. If using a Notebook (SITBIC960lab - Software), parameter settings are also dependant on the code level. (for more information about controlling the automatic firing device using a laptop, see "operating using a laptop").

Attention: After a Reset at the TopTronicT® the parameters ad the automatic gas firing devise will not be resetted to basic setting.

2.9 Reference values in the case of bus interruptionIf there is an interruption in the bus connection between the TopTronicT®/UG and the automatic firing device, the automatic firing device begins to operate in emergency mode, which means that a set value of 75°C (parameter 8) is adopted. In addition, the error message “DATABUS ERROR 70-6” is displayed on the TopTronic®T/UG.

3. Description of the parametersThe parameters can be set using the parameter tree of the TopTronicT®/UG, and also using the SITBIC960lab - Soft-ware on a Notebook. On SITBIC960lab-software, the parameters are not indicated with a number, but with a number and letter combination, which can be seen below in brackets.

Parameter 1 (2AA): Blocking temperature The value of the parameter determines at what boiler sensor temperature the burner is switched off. (“B:08“)

Parameter 2 (2AC): Maximum reference value The reference value, which is set in manual operation, and/or which is calculated by the TopTronicT®/UG in auto-matic operation, is here limited to a set value.

Parameter 3 (2AD): Switch-off hysteresis above reference value If during a heat demand, the temperature rises above the reference value plus the value entered here, the burner switches off. See functional drawing 1.

Parameter 4 (2AE): Switch-on difference relating to tripping point When the temperature falls below the reference value + switch-off hysteresis (Parameter 3) – switch-on difference (Parameter 4), the burner demand is activated. See functional drawing 1.

If this is exceeded, is resulted in a reduction in the number of rotations to the minimum rotation number.

Parameter 11 (2AL): “Low” flow temperatureThe parameter, necessary for controlling the temperature increase at low flow temperatures, can be assigned a value here. See functional drawing 2.

Parameter 12 (2AM): “High” flow temperatureThe parameter, necessary for controlling the temperature increase at high flow temperatures, can be assigned a value here. See functional drawing 2.

Parameter 31 (2FJ): Upward ramp of the fan during ventingIf the number of rotations changes during venting, a higher number of rotations can be achieved using the upward ramp set here.

Parameter 32 (2FK): Downward ramp of the fan during ventingIf the number of rotations changes during venting, a lower number of rotations can be achieved using the downward ramp set here.

Parameter 33 (2FL): Upward ramp of the fan during operationIf the number of rotations changes during operation, a higher number of rotations is limited using the upward ramp set here.

Parameter 34 (2FM): Downward ramp of the fan during operationIf the number of rotations changes during operation, a lower number of rotations is limited using the downward ramp set here.

Parameter 35 (2FN): Post-venting of the fan after lock-outIf lock-out occurs (not on the occurrence of a blocking or other boiler switch-off) post-venting occurs for the period set under this parameter, and at a speed set under Parameter 36.

Parameter 36 (2FO): Fan speed after a normal switch-off or after lock-out/blockingAfter lock-out and/or blocking has occurred, or after switch-off has occurred in normal operation, the fan will operate at the speed set here for the period of time set under Parameter 35 or Parameter 37.

Parameter 37 (2FR): Fan-afterrun-time after operation or blockingAfter a heat demand and/or after blocking of the boiler, the fan operates for the period of time defined here, and at the speed set under Parameter 36.

Parameter 38 (2FU): Fan speed at boiler-freeze-protectionIf the boiler is not in operation and the temperature of flow temperature sensor 1 falls below the 3°C limit, the boiler starts up and operates with the fan speed set here until the switch-off limit of 10°C is exceeded.

Parameter 39 (2GA): Waiting time after opening main gas valve or activation of heating room fanIf there is a burner demand, the boiler start is delayed for the period of time set here. During this waiting period, which is necessary for the opening of the main gas valve or for pre-venting using the heating room fan, the blocking notification “B:04” is shown. This blocking is no longer shown as of BIC 960 V.3. The ext. gas valve closes again as soon as the burner has switched off.

Parameter 40 (2GB): External main gas valve/heating room fan availableThis parameter defines whether or not an external main gas valve or a heating room fan is available.

Parameter 41 (2HA): Afterrun heating pump or shut-off valveIf the boiler switches off because there is no longer a demand for heat, an afterrun of the heating pump or shut-off valve occurs. The duration of this afterrun can be set using this parameter.Note: if the boiler switches off due to blocking or lock-out, or because the reference value + hysteresis has been exceeded, this afterrun period does not occur, and the pump and/or shut-off valve continue to operate indefinitely.

Parameter 46 (2NA): Setting water pressure sensor - ADC/4-value at 0 barThe set values of the water pressure sensor are used to indicate the actual water pressure via the voltage delivered from the sensor. The value set here is responsible for the correct display of water pressure at 0 bar water pressure. Between the two available set values (set value at 0 bar and 6 bar) there is a linear relationship.

Parameter 47 (2NB): Setting water pressure sensor - ADC/4-value at 10 barThe set values of the water pressure sensor are used to indicate the actual water pressure via the voltage delivered from the sensor.

6. Monitoring of warnings and/or faultsIf a warning or a fault (blocking or lock-out) occurs, a flashing code appears on the display of the TopTronic®T/UG, alternating with the normal display. This code provides information about the cause. The following codes appear on the display:

Heat gener. X:xx“ W:xx Warnings B:xx Blockings E:xx Lock-outsWarnings can lead to restricted boiler operation (e.g. capacity limits), and blockings always cause a shut off at the boi ler. Both signals are automatically reset as soon as the cause of the error is eliminated. The boi ler can then re-sume operation. Faults that cause a lock-out must be acknowledged using the reset key, in order to restart the boiler, provided that the cause of the fault has been rectified. Faults on the automatic firing device are acknowledged using the reset key under the flip cover on the front of the TopTronic®T/UG.

Warnings:W:01 = Water pressure too lowIf water pressure falls below the water pressure warning level set under Parameter 17, boiler capacity is reduced to the capacity set under Parameter 24.

W:02 = Ionisation too lowAppears if the ionisation warning limit set under Parameter 25 is under run.

Blockings:B:03 = Gas pressure too low/ Gas pressure switch defective/ external blockings (e.g.: condensate maximum limit, emergency off etc.)Appears when the gas pressure is too low and there is a demand at the boiler. Blockings with an external cause also cause the same error code to be displayed (X9-1/X9-2).

B:04 = Main gas valve (possibly LPG- valve)/ Heating room fan Appears during the waiting time (Parameter 39) until the burner starts.Blocking is no longer shown as of BIC 960 V.3.

B:05 = Water pressure outside of limitsAppears if the water pressure exceeds or falls below the set limits (min: Parameter 19, max: Parameter 21). A blocking is caused.

B:06 = Safety limit thermostat activatedIf the safety limit thermostat is activated, this causes immediate blocking, which changes to a lock-out if activated for more than 5 seconds.

B:07 = Flue gas temperature too highAppears if the flue gas temperature set under Parameter 14 is exceeded.

B:08 = Boiler temperature too highAppears if the boiler temperature limit set under Parameter 1 is exceeded.

Lock-outs:E:01 = Flue gas sensor shorted (X8-2/X8-7)

E:02 = Flue gas sensor interrupted (X8-2/X8-7)

E:03 = Fan speed deviation on ignition.Appears when, after 4 start attempts the start is interrupted due to an excessive deviation of the actual speed from the setpoint speed setting.

E:05 = Flow temperature sensor 2 shorted (X8-3/X8-8)

E:06 = Flow temperature sensor 2 interrupted (X8-3/X8-8)

E:07 = Flow temperature sensor 2 lock-out temperature exceeded Appears if the lock-out temperature of 110°C is exceeded on flow sensor 2.

E:08 = Flow temperature sensor 1 lock-out temperature exceededAppears if the lock-out temperature of 110°C is exceeded on flow sensor 1.

E:09 = Difference between flow sensors 1+2 too highAppears if the difference between the two flow sensors exceeds 10°C.

E:10 = Flow temperature sensor 1 shorted (X8-1/X8-6)

E:11 = Flow temperature sensor 1 interrupted (X8-1/X8-6)

E:12 = Internal error in automatic firing device

E:13 = Parameter loadedAfter a parameter set is loaded on the automatic firing device, the boiler is locked automatically. After pressing “re-set”, boiler operation can be resumed.

E:14 = Parameter loading errorA connection error has occurred when loading the parameter using SITBIC960lab. The process should be repeated.


E:16 = Water pressure too highAppears if the water pressure limit set under Parameter 23 is exceeded.


E:18 = Fan rotation below limitAppears if the number of fan rotations falls below the reference value for 30 seconds or in case of a defective fresh air damper (option to UG (1700D)).

E:19 = Fan rotation above limitAppears if the number of fan rotations exceeds the reference value for 30 seconds.

E:20 = Flame interruption during operationAppears if the ionisation falls below 1.5 µA more than three times during one single heat demand. With the boiler type UltraGas (15-90) the threshold value is being increased to 2.5 µA on-site for monitoring the ionisation.

E:21 = No flame after ignitionAppears when no flame is detected after 4 ignition attempts or in case of a defective fresh air damper (option from UG (2000D)).

E:22 = Air pressure switch does not open(not used)

E:23 = Air pressure switch does not close(not used)

E:24 = Flame detected without reasonAppears when a flame is detected, although the gas valve is closed.

E:25 = Flue gas temperature too highAppears if the flue gas temperature limit, set under Parameter 13, is exceeded.

E:26 = Safety limit thermostat activatedIf the safety limit thermostat is activated, this causes immediate blocking, which changes to a lock-out if the situation persists for more than 30 seconds (X9-1/X9-6).


E:28 = Several gas pressure drops during start-upAppears if the gas pressure switch is released on four consecutive start-up attempts within the safety time (immedi-ately after opening of the gas valve)

7. operation using a laptopAn interfacing cable can be connected from a laptop to socket X11 on the automatic firing device in order to set pa-rameters and/or monitor the system. SITBIC960lab software offers several options for reading in formation from the automatic firing device and for inputing settings. The following basic functions are available: Printing parameter settings Saving parameter settings in a text file Downloading parameter settings from the connected automatic firing device Loading parameter settings to the connected automatic firing device Open saved parameter settings Save parameter settings in a file Load fault data from the automatic firing device Save fault data in a file Recall saved fault data Status display to show the most important information Diagram mode for displaying and saving the trends of the system values Change language Restriction of user level using code inputDue to the presence of different automatic firing unit versions there are various SITlab versions. Each of the SITlab versions recognizes, prior to calling up parameters from a file (prior to loading to or from the automatic firing unit) whether the correct SITlab version is in use. The utilized SITlab version would have to be changed in the event of an appropriate error message.It is important when using SITlab software that the fan must be at standstill when loading parameters (from or to the automatic firing unit), otherwise there must be an interlocked fault at the automatic device.

8. Interfaces to BIC 960The BIC 960 automatic firing device has a RS485 interface for communication with the TopTronic®T/UG. Connect-able controllers and room stations can then be connected to the TopTronic®T/UG via the T2B bus. Connection to a laptop occurs via the RS232 interface (X11).

Attention:The automatic gas firing device BIC 960 which must be used for the CompactGas® boiler does not correspond with the BIC 960 used with the UltraGas® boiler.Therefore when exchanging an automatic gas firing device on a CompactGas®, an article No. 6017 963 must be installed in the ordered BIC 960.Otherwise the locking fault E:02 would be displayed which cannot be acknowledged because no flue gas sensor is installed in the CompactGas®.

Blocking temperature to max. 100°C on request.
