Multi room outdoor units have different maximum capacities of heating kW and cooling kW. Depending on the indoor units chosen, the actual capacity of heating/cooling produced by the indoor unit may vary from the actual rated capacity. This is because the power of the outdoor unit is distributed across all the connected indoor units that are running.
For example, if you have an GE42 and a GE50 indoor unit on an MXZ-3E54VAD outdoor, when the two indoor units operate simultaneously in heating mode, the GE42 will produce up to 3.1kW, and the GE50 will only produce 3.7kW of its rated heating capacity. When only one of the indoor units is running, for example the GE50, you will receive up to an impressive 6.8kW of rated heating capacity from the GE50 alone.
