NOTE:
■ If using the pulse signal in an external input, it is required that the pulse width and the pulse interval of the
external input are more than 500m/sec.
■ A Level input signal and pulse input signal can NOT be set at the same time.
■ It is impossible to set any content which may differ with any one of the external inputs.
■ Even during level signal input, if a setting is set as disabled, when the level signal cancellation is done, it is
not possible to return to the previous setting.
■ In the event that multiple signals are input simultaneously (If the setting is a [Level input signal]), the control
setup will follow the established order of precedence for external input from 1 to 8, and commands are
executed accordingly.
■ If [RC all prohibited] and [Level signal input] are combined, the operation direction for the indoor unit from
this system will be disabled during the external input.
Level Input Signal
NOTICE:
■ Input signal
If the Level input signal is selected, the signal shall remain in effect only while receiving that signal.
If the Pulse input signal is selected, the signal shall remain in effect even after this signal stops.
Only Level input signal can be applicable to the Mode switch, Emergency stop, Outdoor unit capacity,
and lower noise levels.
■ Setting Outdoor Units
To activate “Outdoor unit capacity” in [Monitor], [Schedule], or [External input], (or in both Schedule and
External input), go to [Settings] > [Outdoor unit] and check “Capacity control”.
The [Capacity control] is a function regarding energy consumption at the COOL rating and which is saved
by near designated percent of level of energy consumption.
The setting takes effect within around 15 minutes after external input is entered.
Even if the capacity control performs at 0%, because the standby power consumption (*) is generated,
the consumption of power cannot amount to zero (“0”). The symbol (*): indicates that standby power
consumption is a power used when an AC unit has stopped running and to prepare for the next operation.
The [Capacity control] is unable to function when the outdoor unit is starting control or defrosting.
This control does not guarantee any definite power consumption amount as in the setting.
To activate “Lower noise” from [Monitor], [Schedule], or [External input], (or both Schedule and External
input), go to [Settings] > [Outdoor unit] and select “Lower noise”.
As [Capacity control] or “Lower noise” control are performed, they are always set to one central controller.
When Outdoor unit capacity or lower noise are performed, depending on the external input, Outdoor unit
capacity or lower noise depending on the schedule will be disabled.
The enable/disable function of [Capacity Control] and [Lower Noise] with the setting range may differ
depending on corresponding Outdoor unit. Concerning the corresponding Outdoor unit, please contact
your contractor or distributor.
• When performing the Outdoor unit capacity control and the Lower Noise, set at least one Central
Controller.
• Depending on the External Input, when performing Capacity Control or Lower Noise, the External Input
in process will disable the Capacity Control or Lower Noise depending on the schedule.
NOTE:
■ Outdoor unit capacity follows the set order of priority for the external input and when an input is canceled,
Outdoor unit capacity which is set to the other highest external input in order of priority will performed.
