Lambda probe
Residual oxygen content
Display of the current residual oxygen content.
Lambda probe status
The following status displays are possible:
▪ Off
▪ Pre-heating
▪ Normal operation
▪ Cooling
▪ Reheating
▪ Error
Lambda probe type
Setting the Lambda probe type used:
▪ Bosch broadband probe
(item number: 69001A, “broadband probe” socket)
▪ NTK broadband probe
(item number: 69003, “broadband probe” socket)
▪ Bosch switching-type sensor
(type LSM11, “Lambda probe” socket)
▪ NTK switching-type sensor
(type OZA685, item number: 69400, “Lambda probe”
socket)
Lambda probe heating
▪ A 0: Automatic, Off; A 1: Automatic, On
▪ 1: Manual, On
▪ 0: Manual, Off
Lambda probe calibration (probe must be at 21%
O2)
▪ YES: After activation of the Lambda probe heating, the
Lambda probe can be calibrated.
NOTICE!The Lambda probe must be at 21% oxygen
(air)!
Automatic lambda probe calibration active
▪ YES: If the boiler is in one of these statuses (“Boiler
off”,“Off”, or “Standby”) for a minimum period, which
can be set (“Minimum time at standstill”), the
broadband probe will be calibrated to 21%.
For boilers with automatic loading, calibration is carried
out at the next start (status “Preparation”).
For boilers with manual loading, the boiler changes to
the “sensor check” status after this time has elapsed
(additional indication on the display). The ID fan is
activated and the secondary air is completely opened.
If the insulated door is opened in this status, the
process is aborted.
The prerequisite for calibration is that the probe
provides a stable measurement for one minute. If the
measurement exceeds 21% for more than one minute,
the probe is also calibrated, regardless of the standstill
times.
Minimum time at standstill
Defines the duration that the boiler must be in “Boiler Off”,
“Off” or “Standby” mode to start automatic Lambda sensor
calibration.
Residual oxygen, above which the lambda probe is
allowed to switch off
If the boiler switches to “Boiler off” or “Off” mode, the
lambda probe heating remains active for at least 1 hour,
up to a maximum of 24 hours. If the residual oxygen
content exceeds the value set here, the lambda probe
heating is switched off.
Heating up time for lambda probe
Time for the heating up cycle of the lambda probe.
