(4) Set the temperature setpoint.

NOTES:

Custom Auto:
Set the set temperature for cooling and the set temperature for heating separately. During the Custom 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 to 30 °C (64 to 88 °F) or 20 to 30 °C (68 to 88 °F)
Heat 10 to 30 °C (48 to 88 °F)
Custom Auto Same as the above range, but there are temperatures that cannot be set due to the deadband.
Auto* 18 to 30 °C (64 to 88 °F) or 20 to 30 °C (68 to 88 °F)
The lower limit of the setting temperature is different depending on 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 Custom Auto mode.
The difference between the set temperature for cooling and heating in Custom Auto mode cannot be smaller than the deadband. The deadband is set in the indoor unit. To change this, consult authorized service personnel.
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".

(5) Set the operation mode.

NOTES:

When the operation mode is set while its setting is limited, it is not reflected in the indoor unit even if saved. If the changed setting is not reflected in the operation mode, confirm that the operation mode is active.
When the Wired Remote Controller (UTY-RNRUZx) is connected to VRF indoor unit registered in the Zone and the indoor unit is not set to Dual Setpoint Auto, either this Thermal ZFC or the Wired Remote Controller, whichever is operated later, can execute Auto mode.
