If the Negative Draft falls in the combusion chamber under the
Set Value
, the speed
of the flue gas fan increases. Increases the negative draft, the speed of the flue gas
fan reduces again. Value = 0, the Negative Draft control is inactive. (Displayed only
with connected Negative Draft measuring)
Malfunction Time
If the negative pressure in the combustion chamber is below longer than the adjusted
error time, the system shows the malfunction „Flue gas fan???“
Minimum
If the negative draft
Minimum
in the combustion chamber is below and for longer
than 1 minute, the system goes into Malfunction. Value = 0 the Negative Draft control
is inactive. (Displayed only with connected Negative Draft measuring)
Maximum
If the negative draft
Maximum
in the combustion chamber is exceeded for longer
than 1 minute, the system goes into Malfunction. (Displayed only with connected
Negative Draft measuring)
Washing
The function
Washing
is only available at condensing boiler systems. If the
in
Washing
adjusted Negative Draft falls below, the scrubber cleans the heat
exchanger of the condensing boiler. The Washing occurs to the opposed washing
duration and the washing interval, though maximum 1x per hour.
