Control System
Air conditioner interlock system (commercial multi air conditioners (building multi) /SkyAir)
1 group interlocking control
(standard system)
Perform energy-saving interlocked control
of Heat Reclaim Ventilator Unit using the
remote controller for commercial multi air
conditioners (building multi) /SkyAir.
During intermediate periods, independent
operation of Heat Reclaim Ventilator Unit
is possible with a remote controller for air
conditioner.
Indoor unit
Remote controller
Energy-saving interlocked operation is performed by operating the remote controller for
indoor unit of commercial multi air conditioners (building multi) /SkyAir.
Ventilation mode and rate can be switched for BRC1H62, BRC1E63.
Other settings are made in the field setting mode.
Up to 16 units of a combination of Heat
Reclaim Ventilator Unit and indoor units
of commercial multi air conditioners
(building multi) /SkyAir under energy-saving
interlocking (within the same group)
Total remote controller wiring length: Up
to 500m
Add BRC1H62 to perform control
by 2 remote controllers.

1 group interlocking control
(duct direct connection system)
Energy-saving interlocked control by duct
connection of Heat Reclaim Ventilator Unit and
indoor unit of commercial multi air conditioners
(building multi) /SkyAir within the same group.
※This is available only during interlock using
remote controller lines.

Up to 16 units of a combination of Heat
Reclaim Ventilator Unit and indoor units
of commercial multi air conditioners
(building multi) /SkyAir under energy-saving
interlocking by duct direct connection (within
the same group)
Total remote controller wiring length: Up to
500m
Be sure to set duct direct connection to
"Yes".
Heat Reclaim Ventilator Unit operates only
when the air conditioner fan is in operation
to prevent dust from falling from indoor unit
of commercial multi air conditioners (building
multi) /SkyAir. Therefore, independent
operation of Heat Reclaim Ventilator Unit is
not allowed during intermediate periods. Air
conditioner is used in fan operation.
24-hour operation setting and intermittent
weak notch operation are not available for
duct direct connection system.
32
Interlocking control of 2 or more groups
Perform energy-saving interlocked control of 2 or more
groups of Heat Reclaim Ventilator Unit and indoor unit
of commercial multi air conditioners (building multi) /
SkyAir.
Heat Reclaim Ventilator Unit operates if any of the
indoor units starts operation.
During intermediate periods, independent operation
of Heat Reclaim Ventilator Unit is also possible with a
remote controller for air conditioner.

█ Wiring adapter for electrical appendices
KRP2A Series (use the applicable models)
〔 One adapter connection is provided to the
centralized transmission line. Adapter can also
be connected to the air conditioner.
Energy-saving interlocked operation of Heat Reclaim
Ventilator Unit is performed if any of the indoor units on
the same centralized transmission line starts operation.
※ All air conditioners in the system will be interlocked.
Be careful if there are many separate groups.
The maximum total number of groups is 64 groups
Max. length of centralized transmission line: Up to
1000m
Duct direct connection is not allowed
Set the zone interlock to "Yes".
