Infra-red scene control
The infra-red scene control parameters are used to configure the scene recall behaviour when the sensor is used with
the UHS7 remote control handset. This handset provides eight scene recall buttons, dim up/down buttons and on/off
buttons. As KNX defines a maximum of 64 scenes per group object, the parameter page allows these scenes to be
mapped to the 8 remote control buttons.
In addition, the on/off buttons may be used to transmit a simple switch telegram, or alternatively used to recall an
additional two scenes. This would allow the 'off' scene to preserve a low level of light at all times.
Dim up/dim down buttons are provided for direct control of the dimmer; the dimming interval may also be set. Note that
variations to brightness using this method will not be 'saved' by the dimmer; subsequent scene recalls will revert to
programmed values.
