10.2.1 DIR.ACTUATOR -
effective direction of the actuator
Use this function to set the effective direction between the aeration state of the actuator and the actual position.
Factory setting: rise
Direct effective direction (deaerated → 0 %; aerated 100 %)
Rise:
Inverse effective direction (deaerated → 100 %; aerated 0 %)
Case:
Actual
position
deaerated
