5.1.11 Post-ventilation time
Select parameter 758
No FMS ETA Short Text Description Min Max Default
729 1 2 stopVERB Minimum running time of compound 10 999 10
Minimum running time of the compound (in seconds)

Set the minimum running time of the compound in sec-
onds. This parameter slows down the ramp-up time or
ramp-down time of the burner from base firing-rate to
high firing-rate.
No FMS ETA Short Text Description Min Max Default
758 1 1 ZEIT NA Post-ventilating time 0 1000 0
Post-ventilation time (in seconds)
0 = no post-ventilation

1000 = continuous ventilation (from 5.0 on)
Set the duration, how long the VMS/FMS/ETAMATIC
ventilates after a switch OFF. The air flaps were open
for this purpose. A fan output runs to 20mA. The FMS/
ETAMATIC holds the release signal of the fan.
No post ventilation occurs if the parameter content is 0
and in the case of a fault shutdown.
The actuators are not monitored in post ventilation
mode! The actuators only open when the flame is extin-
guished. The time begins to run immediately with clos-
ing of the magnetic valves. It may be necessary to add
this post burn time to the required post ventilation time
