NOTICE
Conflicting operation
The requirement of setting the panel to either local or remote control prevents
operating the panel locally and centrally at the same time.
For any local operations ─ manual or electrical ─ set the panel to local
control, for example by switching the local-remote switch to LOCAL
position.
NOTICE
Covered control elements
For safety reasons,
charging / discharging the spring energy store are covered by the control door.
