KNX presence detector PlanoCentro A-KNX
3.
Manual operation with push buttons
The presence detector can be overridden using push buttons or by other commands. It is important to know that no separate push button input
objects are required. On the contrary, the presence detector responds to telegrams sent directly to the actuators by the push buttons or superior
functions. In addition, the same group address is used for the push button output, the detector output and the actuator input.
For examples see

9.1.6 „Constant light control, additional manual override via push button“ page 46
Manual operation applies exclusively to the light outputs. The presence, monitoring and brightness outputs are not affected by manual operation.
3.1 Manual operation with switching control type
If the lighting is manually operated using the switching control type, the presence detector shows the following behaviour:
Push button operation
Behaviour of lighting / presence detector
ON telegram
The lighting remains switched on for 30 minutes if the room is occupied.
The light measurement is reactivated after the 30 minutes. An OFF telegram is sent at sufficient brightness.
If the room is vacated before the 30 minutes has expired, the light will switch off normally after the com-
pletion of the set switch-off delay time.
OFF telegram
The lighting remains switched off while the room is occupied. The detector returns to normal switching
mode after the room is vacated and after expiry of the switch-off delay.
3.2 Manual operation with constant light control control type
If the lighting is manually operated using the constant light control control type, the presence detector shows the following behaviour:
Push button operation
Behaviour of lighting / presence detector
ON telegram
The constant light control is activated. The presence detector controls the lighting dependent on
brightness.
Dimming telegram (4 bit)
Value telegram (1 byte)
The control remains switched off while the room is occupied.
The detector returns to standard operating mode after the room is vacated and after expiry of the
switch-off delay.
OFF telegram
The lighting remains switched off while the room is occupied. The detector returns to normal standard
operating mode after the room is vacated and after expiry of the switch-off delay.
3.3 Manual operation using two light outputs A, B.
A separate push button with separate group address is used for each of the two light channels for manual override if the two A,B channels light
are used.
Each of the two A,B channels light can be switched on or off separately with the <control type> "switching".
With the <control type> "constant light control"
both A,B channels always switch on if one of the two push buttons is pressed. It is not possible to
switch on just one of the two lighting groups. On the other hand, each channel can be separately switched off using constant light control.
A,B channels can be separately dimmed.
