Demand Setting (Setting of an External Input)
Give careful attention to the following when using the demand function of the external input setting.
Ɣ Concerning Stop or Operation Mode Shift
Either the stop or the operation mode shift can be set. In addition, note that it is not possible to set
multiple contacts.
Ɣ Concerning Outdoor Capacity Control
This function is used to save on power consumption and keep it near the set value (%). The level
of power consumption conservation is not guaranteed. Power consumption theoretically cannot be
]HUREHFDXVHRIVWDQGE\SRZHUHYHQLIWKHVHWYDOXHLV&DSDFLW\FRQWUROLVQRWDYDLODEOHZKHQ
the outdoor unit is in start-up control or in a defrosting operation.
Ɣ After inputting the contact signal, it will require a maximum of six minutes until control
begins to respond.
If there is multiple signal input into multiple contacts, control will begin from the highest priority in
order of: (input 1 > input 2 > input 3 > input 4).
Ɣ The control target will only be the one outdoor unit compatible with outdoor unit capacity control.
The adjustable capacity value setting or compliance/non-compliance for this function may differ
depending on the type of outdoor unit. Contact your distributor for detailed information.
OFF Time Remote Control Prohibition
Observe the following: When setting the OFF Time Remote Control Prohibition as “Enable”:
Ɣ When setting as “Enable”, the Remote Operation Prohibited (By function), cannot be set.
The Remote Operation Prohibited (All functions) can be set but, DO NOT set it when operating
simultaneously with other controllers. (Refer to “Using Simultaneously with Other Central Controller”
in the below item.)
Remote Operation Prohibited (by function)
This function is used to restrict the operation of the local remote control.
When the Remote Operation is prohibited (by function), the selected functions cannot operate (RUN/
STOP, Operation Mode, Fan Speed, Louver, and Temperature Setting). Both the indoor unit and the local
remote control can be used together only if they are compatible and interconnected with this function.
Pay close attention to the following groups compatible with the remote operation prohibited (by function).
Ɣ The lock function of the local remote control cannot be used when prohibition of the remote control
operation is set.
Ɣ When prohibition of the remote control operation and the lock function are used at the same time,
prohibition of the remote control operation assumes priority. Therefore, the lock function of the local
remote control cannot be set.
Ɣ When the prohibition of the remote control operation (by function), is change to the prohibition of
the remote control operation (all functions), the lock operation setting of the local remote control is
cancelled.
Ɣ When a communication failure has occurred, prohibition of the remote control operation (by
function), can be cancelled. If this happens, perform the setting again.
When Connecting an additional Wired Controller:
When using additional wired controllers, select “Checking Connection” from the Service Menu and
perform the Group Register. Then, switch the power OFF and ON.
Using simultaneously with Other Central Controller
Observe the following when using other central controllers:
Ɣ Do not set the External Input as Emergency STOP, STOP, (Demand Function setting), or Operation
Mode Shift (Demand Function setting).
Ɣ Concerning the outdoor unit capacity control for the setting of External Input, perform the settings
for ONLY one central controller (DO NOT perform settings for the other central controllers).
Ɣ An indoor unit without a remote control cannot be connected.
