The condensation symbol is displayed during temporary override and the fault
"Condensation in room" is sent via bus.
The input must be commissioned accordingly (P38, P42) (see section 3.8).
If the "Button lock" function is enabled via P14, the buttons will be locked or
unlocked by pressing the right button for 3 seconds.
If "Auto lock" is configured, the thermostat will automatically lock the buttons 10
seconds after the last adjustment.
3.6 Control
sequences
3.6.1 Sequences overview (setting via P01)
The mode of the control sequence can be set via P01. Depending on the selected
application, it will have an impact either on the air or water sequence.
On all applications the changeover of the air sequence can be effected via the
supply air temperature sent by the primary controller.
The available sequences depend on the type of application:
