Description
Used to temporarily prohibit the applicable outdoor unit
from operating should there be any faulty part in multi-
outdoor-unit system. Since the comfortable environment
is extremely impaired, prompt replacement of the part is
required.
Make this setting to shorten the BS Cool-Heat selection
control time.
However, make the setting, pay careful attention to the
following:
• If the refrigerant piping between each BS unit
connected to outdoor unit and indoor unit is not more
than 10 m in length, this setting will be enabled.
• If the refrigerant piping between BS unit and indoor unit
is long in length, refrigerant passing sounds may
become louder at the time of BS Cool-Heat selection.
• This setting shortens the Cool-Heat selection time of all
BS units provided in the same refrigerant system.
Make this setting to prevent a rise in room temperature
due to minute heating capacity generated by heating
thermostat OFF unit or non-heating-operation unit while
in heating operation.
• Used to prevent minute heating operation by setting
the BS unit to COOL while in heating thermostat OFF
or non-heating-operation mode.
• With the BS unit set to default, enabling the minute
heating prevention setting of outdoor unit will enable
the minute heating prevention setting of all BS units
connected to the outdoor unit. (BS unit default setting)
• To make this setting by BS unit, make a change to the
minute heating prevention setting of the BS unit. (In
this case, enable the outdoor unit setting.)
Set up master and slave units for multi-connection
outdoor units.
