)
Parameter
NumberTauSuspend
determines the factor for the calculation of O
2
block time.
O
2
block time =
Tau Low-Fire
x
NumberTauSuspend
Due to the reaction and settling time of the O
2
sensor, the O
2
regulator is initially
blocked at burner start. The O
2
block time starts in operating setting (phase 60).
After the block time the W-FM initialises the O
2
regulator and releases O
2
trim after
a further 4 x
Tau Low-Fire
.
As the two possible O
2
sensors differ in reaction and settling time,
Number-
TauSuspend
depends on the sensor used.

The block time also applies to the function CO monitor and CO controller
[ch. 6.11].
At burner start, the CO content is increased. Once the flame has formed and stabil-
ised, the CO content drops. If the block time is too short, the increased CO con-
tent at burner start will trigger a safety shutdown.
Combustion air temperature during commissioning (
Adjust. Temp O2
)
Parameter
Adjust. Temp O2
determines the air temperature during commis-
sioning in conjunction with a supply air sensor, this is not used in the Weishaupt
configuration and has no function.
