Valve outputs | Channel configuration
configured in such a way that the starting state should be tracked at the end of
this function.
Permanent manual operation is now activated. The actuator assumes the
command value of manual operation (e.g. 50%). Whilst manual operation is
active, service mode is deactivated via the KNX. The actuator remains in
manual operation until this is exited via the button field. As no more lower-level
functions are active, the heating actuator evaluates the parameter "Behaviour
at the end of permanent manual operation during bus operation". As this para-
meter is set to "Track outputs", the actuator now evaluates the command value
to be tracked. For this, it checks how the behaviour at the end of service mode
is preset. Here too, the state should be tracked. Thus, the actuator evaluates
the other lower-level functions. As no other functions were and are activated,
the actuator sets the last command value presetting at the valve output using
the KNX telegram (here 10%).
Example 2: Service mode is active (valve completely opened / 100% com-
mand value). A value of 10% was most recently preset via a command value
telegram (normal operation). No other functions are active. Service mode is
configured in such a way that no change should be executed at the end of this
function.
Permanent manual operation is now activated. The actuator assumes the
command value of manual operation (e.g. 50%). Whilst manual operation is
active, service mode is deactivated via the KNX. The actuator remains in
manual operation until this is exited via the button field. As no more lower-level
functions are active, the heating actuator evaluates the parameter "Behaviour
at the end of permanent manual operation during bus operation". As this para-
meter is set to "Track outputs", the actuator now evaluates the command value
to be tracked. For this, it checks how the behaviour at the end of service mode
is preset. There, the configuration states that there should be no change.
Thus, the heating actuator for the affected valve output assumes the com-
mand value of service mode (here 100%) and sets this at the output. In this
case, the actuator no longer evaluates other lower-level functions.
Channel configuration
9.2
To simplify project design, all valve outputs can be activated or deactivated individu-
ally in the ETS. Parameters and communication objects of the deactivated channels
are hidden.
To simplify further, the valve outputs can be assigned to the same parameters and
thus configured identically. The parameter "Parameterisation" stipulates whether
every valve output of the device can be configured individually or whether the para-
meters of valve output 1 are to be applied.
With the setting "like VO 1", the parameter pages in the ETS are reduced. The visible
parameters of the first valve output are then automatically also applied to this valve
output. Only the communication objects can then be configured separately for the
outputs. This setting should be selected, for example, if all the actuators behave
identically and should only be activated by different group addresses (e.g. in office
