Art. No. SC 1000 KNX
-
Parameter "Channel no.":
For each switching time it is necessary to specify which KNX channel it affects. The
parameter "Channel no." assigns the switching time to one of the KNX channels (1...30)
available in the device. Care must be taken to ensure that only channels are allocated that
are also available in the channel configuration in the parameter nodes "channels..." i.e.
were configured with channel functions!
Channels 24...30 are only available and consequently only assignable to a switching time if
no weather station page is configured.
-
Parameter "switching value", "1-byte switching value" and "2-byte switching value":
Depending on the function of the allocated KNX channel, the switching time executes a
channel command when executing a switching time. The aforementioned parameters
specify which channel command has to be executed.
The ETS parameters "switching value", "1-byte switching value" and "2-byte switching
value" are always visible. The function of the allocated KNX channel defines which of these
parameters is enabled (see page 227-228). In the case of the channel function "scene
extension", none of the aforementioned parameters are activated. In these cases, the
channel command of the timer is specified directly by the configuration of the KNX channel.
Thus, the timer is then not able to trigger any other command other than that already
defined in the channel.
In the case of the channel function "operating mode switchover, internal", the channel
command of the timer is defined in the ETS by the enabled parameter "1-byte switching
value". It should be noted here that the device only accepts values within the value range of
the operating mode setting: 1 = Comfort, 2 = Standby, 3 = Night, 4 = Frost/heat protection,
5 = Presence function.
In the case of the channel function "setpoint shift, internal", the channel command of the
timer is defined in the ETS by the enabled parameter "2-byte switching value". It should be
noted here that the device only accepts values within the value range of the setpoint shift
(-4...0...+4). Entered values which contain decimal places are rounded to the nearest whole
number, of course.
i
For the switching times preset in the ETS to be correctly transferred to the device during a
programming operation, the parameter "Overwrite timer parameter" in the parameter node
"Display" must be set to "Yes". Before putting into operation for the first time, this
parameter should be set to "Yes". Otherwise, the switching times preset in the ETS are not
transferred to the device.
If the parameter is configured to "Yes", the switching times changed directly on the device
via the display pages are always overwritten during programming operations. If the setting
is "No", the last configured switching times set on the device remain unchanged during an
ETS programming operation.
i
All parameters for the switching times can also be influenced on the device on the display
pages of the timer. The deletion and reallocation of switching times not only changes
enabled times, weekdays and channel commands, but it is also possible to change
allocations of channels, i.e. to change over from switching a lighting system to controlling a
shading system.
Setting switching times directly on the device
If the device was commissioned with an ETS programming operation, then the switching times
of the timer switch can be edited directly. This requires that the timer be configured centrally as
"available" by the parameter in the ETS of the same name in the "Display" parameter node. The
timer has its own menu that can be recalled via the function page of the main menu level
(figure 109). The menu can be recalled by touching the tile with the
`
icon (1.).
