[VII Control]
-14- Operation Mode
(1) Indoor unit operation mode
The operation mode can be selected from the following 6 modes using the remote controller.
1 Cooling mode
2
Heating mode
3 Dry
mode
4
Automatic cooling/heating
mode
5
Fan mode
6
Stopping mode
(2) Outdoor unit operation mode
1
Cooling only mode All indoor units in operation are in cooling mode.
2 Heating only mode All indoor units in operation are in heating mode.
3 Cooling main mode Coexistence of units in cooling and heating modes.
4
Heating main mode
Coexistence of units in cooling and heating modes.
5 Stopping mode All indoor units are in fan mode or stopping mode.
Note
I
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.
