Description
Used to temporarily prohibit the applicable outdoor unit from
operating should there be any faulty part in the multi-outdoor-
unit system. Since the comfortable environment is extremely
impaired, prompt replacement of the part is required.
Make this setting to prevent a rise in room temperature due
to bleed heating capacity generated by heating thermostat
OFF unit or non-heating-operation unit while in heating
operation.
• Used to prevent bleed 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 bleed heating
prevention setting of outdoor unit will enable the bleed
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 bleed
heating prevention setting of the BS unit. (In this case,
enable the outdoor unit setting.)
Make this setting to shorten the BS Cool-Heat selection
control time.
If making 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 32 ft. (10
meters) 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.
Set up master and slave units for multi-connection outdoor
units.
After setting up, press the
seconds or more.
