750/10
Number of points of an air channel for recirculation
(VMS) / delay time (FMS) in seconds.
With VMS it is necessary to couple the recirculation flap
delay with an air channel during pre-ventilation. There-
fore an air channel is assigned to the recirculation flap
(see P 428). The opening of this air channel now deter-
mines the moment, when the recirculation flap shall
open. Set in this parameter the number of digits the air
channel has to reach, before recirculation becomes
active.
If the device is an ETAMATIC or a FMS, set the delay
time in seconds before the recirculation flap opens,
i. e. during this period only the boiler is ventilated.
The total pre-ventilation duration (P 785) has to be
greater than the value in this parameter.
- VMS opening of the air channel for delay of the
recirculation channel (in digit)
- FMS delay time (in seconds)
0 = recirculation channel remains closed during pre-
ventilation
1... = Delay/delay time of the recirculation channel
