NOTE

• O: allows for individual setting.

• X: the setting is made for all outdoor units.

• –: not used.

• (*1) Temperatures for Floor Exposed Type & Floor Concealed Types are not offset. Setting temperature are used as they are.

• (*2) The “02”, “03”, “04” settings may not be available depending on the type of indoor unit.
  When connecting multiple indoor units, do separate settings.

• (*3) Standard type.

• (*4) It is not applicable for Auto mode.

• (*5) If Duct type models, 00= Increasing fan speed 1 (standard), 01= Increasing fan speed 2 (high static pressure), 02= Standard (low static pressure).

• (*6) Only RPI-(4.0-6.0)FSRE units are affected: Once this optional function is activated from the remote controller (d4=1), normal fan PID control is deactivated, fan motor control starts operating with voltage as a target instead of rpm.
  In this case, duty (output Vsp for fan control) is fixed and it is not recalculated in basis of the target rpm as always does.
  This new feature also avoids the starting PID calculation, means that when a particular fan speed is demanded (e.g.High speed) from zoning system control to Hitachi control, the fan speed is automatically fixed without any possible oscillation.

• (*7) When the unit is restarted by the controller, the temperature automatically changes to the setting temperature of “F5” or “F6”.

• (*8) Applicable to the fan, cooling and dry operation modes.

• (*9) Applicable to the heating operation mode.

• (*10) When the unit is restarted by the controller, the temperature automatically changes to the setting temperature of “F5” or “F6”.

• (*11) Available only for 4-Way Cassette Type, 4-Way Cassette Compact Type, 2-Way Cassette Type, 1-Way Cassette Type, Ceiling Type.

• (*12) Setting “P4” to “01”, then the temperature of selected thermistor (sensor) can be shown.

• (*13) Setting “01” can show sensor temperature selected in “P3”.

NOTE

• On modifying the ”CF” (air outlet louver angle change) setting, restore the power supply or allow the automatic louver to make a full cycle in automatic mode to apply the optional setting.
• The changes to the optional function settings must be done after 3 minutes have passed after startup.
• It is recommended to keep track of the changes made to optional function settings, for further reference.
• The optional settings are different according to the indoor and outdoor unit models. Check to ensure that the unit has the optional setting or not.
• The optional functions with “X” mark at the individual setting column can change the condition only when “All Rooms” is set.

NOTE

• Change the optional setting after waiting at least three minutes elapsed time after start-up.
• Do not set the elevating grille for the total heat exchanger.
• Record the setting conditions for each input and output in the “Setting” column of the table.

5.2.2 Main remote setting
If multiple remote control groups exist in the same outdoor system, main/sub setting is automatically allocated. Set the desired Wired Remote Controller as the “Main” remote controller.
Using this function, a sub remote controller can be set as main.
◆ Example of a refrigeration system containing a group of multiple controllers
Limitations can be faced with such systems as the outdoor and indoor units may not be compatible with all the functions proposed by the wired remote controller. Settings of some functions may also be different between a main and a sub controller, refer to the table below for details.Main Controller — Only One Controller in Same Refrigerant System
Sub Controller — Controller in addition to the Main Controller in the same Refrigerant System
◆ Relation between Main/Sub controller and function settings
NOTE
Concerning main and sub controllers, the range of settings may differ for the functions shown below.

●: Available
×: Not Available

◆ Changing from the sub controller to the main controller

1. Press “ ” and “ ” simultaneously for 3 seconds to start changing from the sub controller to the main controller. The changed screen is displayed.
2. When the change is completed, it returns to the home screen.

NOTE

• When using two controllers, only the primary controller can be set as the main controller.
  In cases where two controllers are both sub controllers, the “Main Remote Setting” is only accessible from the primary controller.

• In case the primary controller is a “Main Controller” and the secondary controller is a “Sub
  Controller”, when the primary controller and the secondary controller are changed by the function selection, Main and Sub controllers will also be switched simultaneously.

• If the main controller “ ” icon is not displayed, the main controller may not function normally. In this case, check the connection wiring on the related wired controller.

• If a remote control group is operating with multiple refrigerant systems, the Outdoor Unit Capacity Control function may not operate normally.

5.3 Service menu
5.3.1 Operation Lock/Unlock setting
This function disables the setting mode of the remote controller.
In the operation lock, when the lock icon “ ” is getting displayed, that means this setting is locked and cannot be changed by the user using the “ ”, “ ”, “ ” or “ ” buttons.
The following settings can be locked:

• Temperature setting (Temp)
• Operation mode (Mode)
• Fan speed
• Louver swing (Louver)

NOTE

• Don’t use the operation lock function when remote control is set to “prohibit” on the central controller.
• If both the “prohibit lock” and “prohibit remote control” operations are set at the same time, the “prohibit remote control” operation has priority.
• If the setting is changed from “prohibit remote control operations” to “permit all remote control operations”, all operation locks are released.

1. Set Operation Lock.
   ✓ Press “ ”, “ ” and “ ” simultaneously for 3 seconds, the lock icon “ ” lights up and the operation lock is in valid.

2. Set Operation Unlock.
   ✓ Press “ ”, “ ” and “ ” simultaneously for 3 seconds, the lock icon “ ” lights up and the operation unlock is in valid.

5.3.2 NFC setting

NOTE
(1) Even if stoppage Alarm “02” is not always indicated. If the unit is Thermo-OFF due to another cause of stoppage prior to alarm occurrence, the code of the cause remains.
(2) The outdoor unit equipped with an inverter resets ODU Micro-Computer if the transmission between inverter PCB and outdoor unit PCB is interrupted for 30 seconds. Therefore, the stoppage cause code when Alarm 04 occurs may be “05”.
(3) IDU Micro-Computer is reset if the transmission between the indoor unit and the outdoor unit is interrupted for 3 minutes. Therefore, the stoppage cause code when Alarm 03 occurs may be “06”.
(4) If the stoppage cause code “21” is indicated on the indoor unit of twin, triple, or quad, check the stoppage cause of other indoor unit numbers. Indoor unit capacity code
