Parameter window A: Characteristic curve correction

This parameter window is enabled if in
characteristic curve has been parameterized with the option yes. In this parameter window, an adaptation
of the valve drive to the valve that is employed can be undertaken using the characteristic curve
correction. A characteristic correction optimizes the control behaviour of the system if required.
Important
A characteristic correction should only be undertaken in exceptional cases, and extensive knowledge in
heating, air-conditioning and ventilation systems is a prerequisite.
The following must be considered with the characteristic curve correction:

The value pairs can be entered in any sequence. They are sorted in ascending order of the control
value in the device, and intermediate values are interpolated.

If no value pair has been entered for the control value 0 %, the valve position of the first value pair
applies for all control from 0 to the first value pair.

If no value pair has been entered for the control value 100 %, the control values from the last value
pair up to 100 % applies for the last value pair.

The parameter
control of the output for the characteristic curve correction, even if control value is processed via a 1
bit value.
Caution
Value pairs with the same control value can cause a non-defined characteristic curve. This fact must be
considered during parameterization.
