Issue
When opening (pulling up) the sunblind, it stops at the end of runtime and then rolls back down. Similarly, when closing (pulling down), it stops at the end of runtime and then rolls back up.

Lonworks devices including REG-N MSE4 (SVEA 32237-346) Sunblind actuators
Cause
The actuator is preconfigured for venetian blinds, which include lamella angle adjustments. For simple sunblinds, these parameters cause unintended motor actions after reaching the end position.
Resolution
For non-venetian blinds:
- Set the following parameters to zero:
UCPTdownPanelAngleUCPTupPanelAngleUCPTpanelTurnTimeUCPTpanelTurnTimeBottom
- Ensure SNVTsetting commands have zero in the rotation part.
This disables unnecessary panel angle adjustments and prevents rollback after full movement.
