Balancing the supply air/extract air flow rates
Note
Balancing is only required if the total of the actual air
flow rates of all supply air apertures deviates by more
than 10 % from that of all extract air apertures.
Vitovent 200-C
To balance out the air flow rate differentials, the control
voltages of the supply and/or exhaust air fan can be
permanently increased or reduced.
1. Service menu:
Press OK +
å
simultaneously and hold for
approx. 4 s.
2. "Parameter level 1"
3. Set the control voltages:
■
"Control voltage matching, supply air fan
7D71"
■
"Control voltage matching, exhaust air fan
7D72"
Vitovent 300-C
1. Service menu:
Press OK +
å
simultaneously and hold for
approx. 4 s.
2. "Parameter level 1"
3. Set "Imbalance permitted C1A2" to "1".
4. An increase or decrease in the supply air flow rate
in comparison to the extract air flow rate can be set
with "Specified imbalance C1A3".
