Setting the priorities of the
operating modes
Table 38: Setting - Priority
The priority setting of the operating modes can be used to determine which operating mode is
switched on with priority if several operating modes are selected. If, for example, comfort and night
are switched on at the same time in the Frost/Comfort/Night/Standby priority, the controller
remains in comfort mode until it is switched off. Then the controller automatically switches to night
mode.
Operating mode switchover
There are 2 possibilities for operating mode switching: On the one hand, the operating mode can be
controlled via the associated 1-bit communications objects and on the other hand, the operating
mode can be controlled via a 1-byte object.
The selection of operating modes via 1 bit is done by direct control of the individual communication
object. Taking into account the set priority, the operating mode controlled via its communication
object is switched on or off. To switch the controller from an operation mode with higher priority to
one with lower priority, the previous operation mode first has to be deactivated with a logical 0. If all
operation modes are switched off, the controller switches to standby mode
Example (set priority: Frost/Comfort/Night/Standby):
