11. Operation mode
(1) Indoor unit operation modes
An operation mode can be selected from the following 5 modes on the remote controller.
1 Cooling mode
2 Heating mode
3 Dry mode
4 Fan mode
5 Stopping mode
(2) Outdoor unit operation modes
Five operation modes of the outdoor units
1 Cooling only
2 Heating only
3
Cooling main
4
Heating main
5
Stopping mode
When the indoor units are in the combination of cooling and heating modes, operation mode
(cooling main or heating main mode) is determined by the outdoor unit based on the refrigerant
pressure and variation rate in the R2 refrigerant circuit.
(3) Patterns of the auto cooling-heating changeover operation
When the auto heating-cooling changeover mode is selected, indoor temperature is detected as shown in the operation
pattern shown below, and the cooling or heating mode is automatically selected.
