Control System
Zone management [Central remote controller (DCS302CA61)]
Purpose • Function
Up to 64 groups of Heat Reclaim Ventilator Unit and indoor units can be connected to make individual/batch start/stop available on
a zone basis together with various monitoring.
※Energy-saving interlocking control and independent ventilation operation is possible within the same zone.
※Ventilation mode and ventilation rate can be switched using DCS302CA61.
POINT
Group number needs to be set for centralized control.
Heat Reclaim Ventilator Unit to be interlocked with air conditioners should be assigned to the same zone as the air conditioners.
In this case, zone interlock setting needs to be made on the Heat Reclaim Ventilator Unit.
ON/OFF operation cannot be performed from the remote controller for Heat Reclaim Ventilator Unit in Zone 1 (settings other than
ON/OFF can be made).
Zone interlock setting is not required for Zone 2. This means that the factory default settings are maintained.
When operation is performed without remote controller, the unit can be operated only from central remote controller.
