I receive an error message with error code “10000”. What does it mean?

The Daikin Online Controller can be installed on multi-indoor systems. In case of multi-indoor systems, the indoor units cannot operate in incompatible operation modes (e.g. cooling and heating). When changing operation modes, the priority will be given to the priority unit (ref. the indoor unit manual for more information). The non-priority units will be put in standby mode in case the operation mode is not matching the selected operation mode on the priority indoor unit.
