-14- Operation Mode
(1) Indoor unit operation mode
The operation mode can be selected from the following 6 modes using the remote controller.
(2) Outdoor unit operation mode
When units in cooing and heating coexist, the operation mode (cooling main mode or heating main mode) will be determined,
based on the refrigerant pressure in the R2 refrigerant circuit and speed variation data.
(3) Operation pattern for automatic cooling/heating mode
When the automatic cooling/heating mode is selected from remote controller functions, the indoor temperature will be detect-
ed in pattern as shown in the figure below, and the operation mode (cooling or heating) will automatically be selected.
(4) Relationship between the operation mode and the load capacity (kW) (within a system)
