DESCRIPTION OF THE PARAMETERS
Parameter 31 (2FJ/32799):
Upward ramp of the fan during venting
If the number of rotations changes during venting, a higher number of rotations can be achieved using the upward
ramp set here.
Parameter 32 (2FK/32800):
Downward ramp of the fan during venting
If the number of rotations changes during venting, a lower number of rotations can be achieved using the downward
ramp set here.
Parameter 33 (2FL/32801):
Upward ramp of the fan during operation
If the number of rotations changes during operation, a higher number of rotations is limited using the upward ramp
set here.
Parameter 34 (2FM/32802):
Downward ramp of the fan during operation
If the number of rotations changes during operation, a lower number of rotations is limited using the downward ramp
set here.
Parameter 35 (2FN/32803):
Post-venting of the fan after lock-out
If 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/32804):
Fan speed after a normal switch-off or after lock-out/blocking
After 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/32805):
Fan afterrun time after operation or blocking
After 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/32806):
Fan speed at boiler freeze protection
If 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/32807):
Waiting time after opening main gas valve or activation of heating room fan
If 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/32808):
External main gas valve/heating room fan available
This parameter defines whether or not an external main gas valve or a heating room fan is available.
Parameter 41 (2HA/32809):
Afterrun heating pump or shut-off valve
If 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.
