Note: When the indoor units support a dual-set-point function, two different set temperatures (one for cooling and the other for heating)
can be set for the Auto mode. When this function is used, indoor units automatically switch over between cooling and heating,
based on the room temperature, to maintain the room temperature within the two predetermined temperatures. The graph below
shows an example of operation patterns of units operated in the dual-set-point mode.
If the indoor units of the selected unit group support the dual-set-point function, two different set temperatures (one for cooling and
the other for heating) can be set.
(1) Temperature setting for a group in which all indoor units support dual-set-point mode
(2) Temperature setting for when the groups that support the dual-set-point mode and the groups that do
not are selected together
