Function:
[0] Disabled : Set-Point compensation not active.
Enabled
[1] :Set-Point compensation is active. Enabling this parameter allows Flow Compensated Setpoint op-
eration.
Function:
Example 1:
Adjustment of this parameter allows the shape of the control curve to be adjusted.
0 = Linear
100% = Ideal shape (theoretical).
