Gewiss GW 90 835 Handbuch Seite 19

When an OFF command is received or when a scene is activates that includes the
actuator OFF command, the relay is deactivated and the countdown cancelled.
The switch-off warning can be enabled with the Prewarning time parameter: in this case
the relay opens briefly (the light turns off momentarily) when, at the end of the time set,
there is the time left set by the parameter. It will thus be possible - if necessary - to send
a new ON command with timer before the light turns off. The green LED turns on when
the relay contact is closed.
EXECUTION OF PRIORITY COMMANDS
The actuator switches the relay to the (ON or OFF) state transmitted by the device (contact
interface) that sends the priority command.
Until it receives a command to stop forcing, the actuator ignores all the other commands
received including those from the front push-buttons.
If no other commands are received, when forcing is finished the actuator returns to the
state before forcing was activated. Otherwise, it will return to the state corresponding to
the last command received.
The green LED turns on when the relay contact is closed.
SCENE MANAGEMENT
Each actuator channel can store and execute up to 8 scenes, each scene associated
with the ON or OFF status of the relay. It is not possible to associate a scene with a timed
activation.
To associate an actuator status with a scene it is necessary to control the output of the
status required (ON/OFF) prior to storing.
The green LED turns on when the relay contact is closed.
