3.6 Control sequences
3.6.1 Sequences overview (setting via parameter P01)
The mode of the control sequence can be set via parameter P01. Depending on
selected application it will have influences either on the air sequence or water
sequence.
In all application the changeover of the air sequence can be done via supply air
temperature sent by the primary controller.
The available sequences depend on the application:
Parameter P01 = 0 P01 = 1 P01 = 2 P01 = 3
