Forcing function
The forced control is very similar to the basic direct command of the output value, but with the peculiarity that
it overrides both the “regular” set value and every other value conditioning feature (i.e. logic function,
staircase timing etc.).
It is possible to set what value the output should assume both when the output forcing is released and also
on recovery after a bus power-off if forcing was previously in effect.

The “Force” command has priority over Locking (which acts on the ordinary on-off command); therefore, a
locked output can still be operated through “Force” commands.
The KNX command code for the “Force” operation is a 2 bit value; the
priority
bit determines whether the output value must be forced, in which
case the
value
bit is assigned to the output.
In the figure above, NP means that the
priority
bit is 0 (No Priority), while
the PON and POFF codes indicate the values with
priority
= 1 and
value
respectively 1 or 0.
