22-51 End of Curve Delay
Range: Function:
10 s* [0 - 600 s] When an end of curve condition is detected, a timer is activated. When the time set in this parameter
expires and the End of Curve condition has been steady in the entire period, the function set in
par. 22-50
End of Curve Function will be activated. If the condition disappears before the timer
expires, the timer will be reset.
22-80 Flow Compensation
Option: Function:
[0] * Disabled [0] Disabled : Setpoint compensation not active.
[1] Enabled [1]
Enabled : Setpoint compensation is active. Enabling this parameter allows the Flow Compensated
Setpoint operation.
22-81 Square-linear Curve Approximation
Range: Function:
100 %* [0 - 100 %] Example 1:
Adjustment of this parameter allows the shape of the control curve to be adjusted.
0 = Linear
100% = Ideal shape (theoretical).
NOTE!
