Register 1:
Setpoint for actuator setting in hundredths of one percent,
i.e. 0...10,000 corresponds to 0...100%
Setpoint
In the case of actuators for fire dampers, the control must be accomplished through the
Override control register (2). Writing access to the setpoint is refused (see Register 6).

Due to safety considerations, the only override values permitted in the case of actuators for fire
dampers are Open (1) and Fast_closed (6). The operating position (Open) must also be
repeated within 120 seconds (recommendation: 90 sec.).
If the override command is not renewed, then the Gateway will move the actuator into safety
position and signal an error (see Register 6). The remaining time for the renewal is visible in
Register 13.
