NOTE:
with pressure transducer mounted, the MENU “
PAr
”
will show a parameter called “
Sprc
”
;
this parameter is the
imbalance of the return flow rate compared to the supply
flow rate.
It can be altered with a range from +20 to -20 (%).
Example: if the parameter set is +10, the return is 10% less
than the supply flow rate.

WARNING!:
In cases where one fan cannot be run at the target
flow rate, message
"
Out of Range
"
is temporarily displayed.
Then, the system steps to next extraction fan balancing or ends
the flow rates setting procedure.
When
"
Out of Range
"
is displayed, last flow rate blown by fan
just before the message is the one set by the system, which is
the flow rate as close as possible to target.
