NOTES:

The information set here is saved on the “Zone setting” screen, but it is not saved on the "Bulk Edit Zones" screen.
Existing information on the "Zone setting" screen is overridden by the information set on this screen.
When the system is in a special state, such as maintenance or operation prohibition, the settings may not be reflected in the indoor unit.

For Auto mode, if all indoor units in the selected Zone are Single Setpoint Auto, the Thermal ZFC for Single is displayed.
For Auto mode, if all indoor units in the selected Zone are Dual Setpoint Auto or Single and Dual are mixed, the Thermal ZFC for dual is displayed.
When the temperature setting range is restricted by “Temperature Limit” setting of the indoor unit registered in Zone, the temperature setpoint setting range that can be set in "Zone Functions" is also restricted in the same way.
When two or more indoor units are registered in Zone, the temperature setpoint setting range by "Zone functions" is restricted by the smallest value of the upper temperature limit and the largest value of the lower temperature limit set by each indoor unit in "Temperature Limit".

Delete the Zone function settings

Select the Menu button (a) of the function to be deleted.
Select [REMOVE] from the Link button.
A confirmation message appears.
Select the button (c).

About Dual Setpoint Auto operation (Dual Setpoint)

Dual Setpoint Auto:
Set the set temperature for cooling and the set temperature for heating separately.
During the Dual Setpoint Auto mode operation, when the room temperature exceeds the set temperature for cooling, the cooling operation is performed, and when the room temperature falls below the set temperature for heating, the heating operation is performed.
(It can be used only when the setting of the indoor unit compatible with this function is valid.)
The settable temperature range is different for each operation mode.
Settable temperature range
Cool/Dry 18°C to 30°C (64°F to 88°F) or 20°C to 30°C (68°F to 88°F)
Heat 10°C to 30°C (48°F to 88°F)
Dual Setpoint Auto Same as the above range, but there are temperatures that cannot be set due to the deadband.
Auto 18°C to 30°C (64°F to 88°F) or 20°C to 30°C (68°F to 88°F)
The lower limit of the settable temperature differs by the place of use.
The heating set temperature range of 10°C to 15°C (48°F to 58°F) may not be settable, depending on the indoor unit model.
Deadband:
The deadband is the minimum value of the difference between the set temperature for cooling and the set temperature for heating (= cooling set temperature - heating set temperature) in Dual Setpoint Auto mode.
The difference between the set temperature for cooling and heating in Dual Setpoint Auto mode cannot be smaller than the deadband.
The deadband is set in the indoor unit.
To change this, consult authorized service personnel.
