(1) Objects used for temperature setting commands from the central monitoring device
Temperature setting objects that can be used differ depending on indoor unit group configuration. When
setting temperature from the central monitoring device, use temperature setting objects that match the indoor
unit group configuration.
Groups for which "Old Model Compatibility Mode" is off, and groups within which all indoor units support
"Dual-set-point mode in the Auto mode" are groups that support "Dual-set-point mode in the Auto mode".
Groups for which "Old Model Compatibility Mode" is on, or groups within which there are indoor units that do
not support "Dual-set-point mode in the Auto mode" are groups that do NOT support "Dual-set-point mode in
the Auto mode".
For groups supporting dual-set-point mode, issue commands using dual-set-point mode objects (AV_xxxx24
to AV_xxxx28); and for groups not supporting dual-set-point mode, issue commands using indoor temperature
set value objects (AV_xxxx10).
If the central monitoring device issues a command for groups that do not support dual-set-point mode using a
dual-set-point mode object, then the AE-200 will return an error to the central monitoring device.

switched on some models of indoor unit.)

Group 2 does not support dual-set-point mode, therefore if the central
monitoring device issues a command using a dual-set-point mode object,
then the AE-200 will return an error to the central monitoring device.
