Holiday function with period activation
The holiday function carries out desired actions during longer periods of absence, for example
lowering the room temperature, lighting scenarios, switching off various functions, etc. The holiday
function is activated via a 1-bit object (on/off) or via a 1-byte object. The 1-bit object is used to
switch the holiday function on or off at different times, while the 1-byte object is used to activate the
holiday function for a fixed period, e.g. 7 days. The status object outputs the remaining days.
With the automatic holiday calculation, holidays can also be enjoyed during the week
The automatic calculation of public holidays can be parameterized individually for all countries. For
Germany and Austria the public holidays of all federal states are preconfigured. Further individual
dates can be added. The holiday event can actively influence the timer. No action or holiday like
Sunday can be set. If the holiday is during the week and the settings are set to holiday like Sunday,
the blinds will move up later during the week and you can start the holiday a little later. (Later time
setting on Sunday assumed). The hot water is also set to get up later, the time of the circulation
pump is also moved back and supplies hot water at a later time when it is needed.
Time function on external display
The timer can send the time telegram cyclically every minute. This enables time displays to be
realized on displays which do not have their own clock function.
4 Direct operating functions
Four direct operating functions are available on the first page of the Central Operating Unit. These
can be executed individually or in groups. Here, important functions such as switching, dimming,
value, scenes, blinds or operating mode changeover can be executed directly. Especially central
functions such as central off, presence, standby or light corridor can be implemented optimally.
20 Operating functions via menu / time switch
In general, a maximum of 24 functions can be managed via the Central Operating Unit Smart. Four
direct operating functions are available, as described above. Twenty functions can be controlled via
manual operating keys and/or the timer. Here, the twenty functions are assigned to a menu with
four function levels (light, blinds, temperature or other). This results in a new manageable operating
concept of the control panel consisting of the upper level with the selection of the function level, the
middle level with the selection of the function, and the lower level with the actual switching function.
Regardless of whether an operating function and/or a timer function is required, it always occupies
one of the twenty functions. The 20 operating functions can be used to control normal switching
functions, blinds/roller shutters, heating/temperature set points, scenes, values and operating
modes. Each time switch function has its own blocking object.
