Conflicts when selecting different modes
When two or more internal parts are in operation, it is important to select a mode that does not conflict
with other internal parts. Heating mode takes priority over every other mode. If an internal part is running
in heating mode, other internal parts can also only work in heating mode. If another mode than heating
mode is selected for an internal part, this internal part will create a conflict and will not function.
Example: If one internal part is in cooling mode and another internal part is set to the heat setting, the
internal part running in cooling mode will create a conflict; this is because the heating mode takes priority.
The internal part running in the cooling setting will indicate a P5 error on the display.
The table below presents an overview of conflict situations:
