Using the System-Changeover function
Main Menu > System Management > System-Changeover
Use the System-Changeover mode to automatically change a group of indoor units that are connected to the same
outdoor unit over between the Cooling and Heating modes according to temperature changes.
Use this function to control the indoor units that do not have an automatic changeover mode. They can be operated in
the Heating mode in the morning, and then automatically changed over to the Cooling or Heating mode all at once in
the afternoon, for example, without the need to manually change the mode via each remote controller.
* This function should not be used in conjunction with the System-Changeover function on the outdoor unit or
other system controllers.
* When the System-Changeover mode is set to [Auto], the operation mode is selected based on the demands
of the majority of the group, taking into consideration the capacity of each indoor unit. When it is set to
[Representative Group], the operation mode is selected based on the demand of the representative group
through updating its status every 15 minutes and changing over to the cooling or heating mode as necessary.
Because the operation mode is selected based on the demands of the representative group or of the majority
of the groups, not all areas may be air conditioned to the optimum temperature.
・
If the temperature limits are set too high or low (see P44), the System-Changeover function may
not work properly and the units may not operate in the expected mode (Cooling or Heating).
・
The System-Changeover function is not available for the following types of products:
Simultaneous Cooling/Heating units (with Auto mode), Mr. SLIM®, LOSSNAY, and DIDO
controller.
