※
Incorporate one of the above models into the applicable commercial multi
air conditioner (multi for buildings).
KRP2A62 if incorporated in Heat Reclaim Ventilator Unit. (Use an applicable
model)
[Unified ON / OFF controller]
Individual start/stop can be set by group
Batch start/stop is possible for each of 16 groups.
Equipped with power terminal for schedule timer.
[Schedule timer]
It is possible to set batch start/stop twice a day on a weekly basis.
With 48 hour backup time for each occurrence of power failure.
[Wiring adapter for electrical appendices]
Simultaneous batch start/stop is possible by external input.
[Remote controller]
Interlocked operation with air conditioner can be performed.
Independent operation of Heat Reclaim Ventilator Unit can be performed.
The maximum total number of groups connected by centralized
transmission line can be up to 64 groups.
Max. length of centralized transmission line: Up to 1000m.
[Unified ON / OFF controller]
Group number for centralized control needs to be set for each group.
Power supply is required.
[Schedule timer]
DC16V power supply is required for stand-alone use. Power can be
supplied from the printed circuit board of the main unit.
((X11A) in case of Heat Reclaim Ventilator Unit)
[Wiring adapter for electrical appendices]
For stand-alone use only. (The adapter can be incorporated into one of
the units.)

Individual or batch start/stop is possible.
A zone consisting of multiple groups can be set.
[Central remote controller]
Energy-saving interlocking operation can be performed by starting/
stopping an air conditioner within the same zone.
Equipped with power terminal for schedule timer.
Ventilation rate and mode can be switched with DCS302CA61.
The maximum total number of groups connected by centralized
transmission line can be up to 64 groups.
Max. length of centralized transmission line: Up to 1000m.
Direct duct connection is not possible when connected by a centralized
transmission line.
Group number for centralized control needs to be set for each group.
Power supply is required.
[Central remote controller]
To perform operations interlocking with air conditioners within the
same zone, field setting using remote controller (to set centralized zone
interlocking to "Yes") is always required.
Do not make this setting if there is no air conditioner (i.e., only Heat
Reclaim Ventilator Unit is present) in the same zone.
