The parameter window - Curve is visible if in parameter window Valve
HEATING the parameter Correct valve characteristic curve has been
selected with the option yes.
The following must be considered with the curve entries:
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 value pairs have the same control value, the value pair with the largest
value position applies. All other value pairs are ignored.
The value pair with the smallest valve position applies for the correction
of the smaller control values.
If no value pair has been entered for the control value 0 %, the valve
position of the first value pair applies for all control values from 0 to the
first value pair.
If no value pair has been entered for the control value 100 %, the valve
position from the last value pair up to 100 % applies for the last value
pair.
Note
The characteristic curve adjustment is active with forced operation.
Caution
A parameterisation of the value pairs with the same control value leads
to an undefined state and should be strictly avoided.
Otherwise it can lead to destruction of the HVAC system.
