Mode selection
Function principle
The function "mode selection" can send up to 4 different operating modes by shortly pressing a
button. The operating modes are switched one after the other. Depending on the set parameters, for
example, at a keystroke the 2nd operating mode is sent if the 1st operating mode has been sent
before or the 3rd operating mode will be sent if the 2nd operating mode has been sent before…
Long keypress
In addition to switchover by a short keystroke, a fixed operating mode can be sent at a long
keystroke.
Here one of the 4 operating modes can be sent. This means that a fixed operating mode
(independent of the last switching value) would always be sent with a long keystroke.
Switching type
Limit stop:
With the switching type "Limit stop" the 4th operating mode is sent again after sending
the 4th operating mode.
Overrun:
In the switching type "Overrun", the 1st operating mode is sent again after the 4th
operating mode.
Note
: For the single-button function, this parameter is set permanently to "Overrun".
Switchover considers status object
If the
status value is not considered
during the switchover, the unit remembers the last value sent
and sends the next or previous value during the next operation without considering whether another
value was sent to the object in the meantime.
If the
status value is considered
during the switchover, the unit sends the next higher or the next
lower switchover value - in relation to the last received status value - at the next actuation.
Status display
If the status on the controller changes (e.g. via Day/Night switchover, frost alarm, etc.) and this is
sent, the display can be updated with this. To display the status correctly, it must be set whether it is
sent as "HVAC status" or as "HVAC mode". According to the selection, a communication object
appears via which the status of the controller is received.
After the update, the button then sends the next switching value when the button is pressed again.
