The parameter window Characteristic Curve is displayed if in parameter
window Functions, the parameter Enable characteristic curve has been
selected 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 ventila-
tion 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 as-
cending order of the control value in the device and intermediate values
are interpolated.
If no value pair is assigned to the "control value 0 %", the first value pair
is always applied for the control values from 0 up to the first value pair.
If no value pair is assigned to the "control value 100 %", the last value
pair is always applied for the control values from the last value pair up
to 100%.
The parameter Cycle time of PWM
ing the control of the outputs for the characteristic curve correction, also
when operating with the control value over 1-Bit-value.
