Table 16: Priority of the operating modes
The setting of the priority enables to adjust which operating mode shall be switched primarily when
more than one operating mode is switched on. At the priority of Frost/Comfort/Night/Standby, the
comfort mode will be switched on even if comfort and night is switched on to the same time. The
night mode will only be active, when the comfort mode is switched off. now the controller changes
automatically to the night mode.
4.4.2.6 Operating mode changeover
There are 2 possibilities for the changeover of the operating modes: On the one hand the operating
modes can be switched on by their 1 Bit communication object and on the other hand by a 1 Byte
object (from Version 1.2).
The selection of the operating modes by their 1 Bit communication object occurs via a direct
selection of their individual communication object. With consideration of the adjusted priority, the
operating mode, which was selected via the 1 Bit communication object, is switched on or off. When
all operating modes are switched off, the controller changes to the standby mode.
Example:
The priority was set as
Frost/Comfort/Night/Standby.
