3.4.12 Own characteristic valve curve
Prof. setting for special valves.
This parameter appears only when an internal characteristic valve curve has been selected
from the "Unit settings" page.
The actuator response can be accurately adjusted using the characteristic valve curve
(manufacturer’s documentation).
This parameter enables the Cheops control to be adjusted on a valve at 9 points of the
characteristic curve (10%.....90%). A certain flow is reached for each point at a certain % of
the valve stroke.
