Centralized management system
Batch/individual management [Unified ON/OFF controller (DCS301BA62)]
Purpose • Function
Batch start/stop of 16 groups or start/stop of individual unit can be performed with one controller.
Up to 128 groups, which consist of 16 groups x 8 units of Unified ON/OFF controllers, can be connected on a single centralized
transmission line (within a system).
Ventilation mode selection is self-determined.
Points
Group number needs to be set by field setting for centralized control. (For all the units connected to (F1) and (F2) terminals of
centralized transmission line) When assigning a group number to Heat Reclaim Ventilator Unit for centralized control, connect a
remote controller to (P1) and (P2) terminals to make the setting. (Contact us for how to make the setting.)
If the system does not require any remote controller, remove the remote controller after the setting is completed.
This system does not perform interlocked operation with air conditioner.
To perform energy-saving interlocked control, consider adopting one of the following systems.
• 1 group interlocking control system (See page 33)
※ In this case, do not connect centralized transmission line of Heat Reclaim Ventilator Unit.
• Zone interlock system using central remote controller (See page 36)
Follows the operation codes of the Unified ON/OFF controller, including prohibition and permission of remote controller. For more
information, please see the installation manual of the Unified ON/OFF controller.
When operations are performed without remote controller, the unit can be operated only from Unified ON/OFF controller.
