CONFLICTS WITH DIFFERENT MODE SELECTIONS
If there are two or more indoor units in service, you must make sure that the selected mode doesn’t
effect the other indoor units. The heating mode has priority on all other modes. If an indoor unit
is running in the heating mode, the other indoor units can also only work in the heating mode. If
another mode is selected for an indoor unit, this will lead to a conflict and will not function.
Example: If an indoor unit is working in the cooling mode and another indoor unit is turned on in the
heating mode, the indoor unit in the cooling mode will cause a conflict, the heating mode will always
have priority. The indoor unit in the cooling mode will send a malfunction message to the display,
namely P5.
