*This figure omits the power supply line and only shows the transmission line.
For example, 5 contacts connected to the DIDO controller are calculated as the equivalent of 5 indoor units connected to
AE-200E/AE-50E/EW-50E/AG-150A/EB-50GU-J.
<Restrictions>
Maximum of 50 units (50 channels) per AE-200E/AE-50E/EW-50E/AG-150A/EB-50GU-J
However, the number of units that can be connected to a AE-200E/AE-50E/EW-50E/AG-150A/EB-50GU-J is up to 50 including
the number of contacts used on this device, an indoor unit, LOSSNAY unit, etc.
Up to 6 contacts can be connected to the DIDO controller (1 M-NET address). One contact connected to this device is calculated as
the equivalent of one indoor unit connected to AE-200E/AE-50E/EW-50E/AG-150A/EB-50GU-J.
NOTE
• For the shield ground of the M-NET centralized control line, use single-point grounding at the power unit for
the transmission line.
However, when supplying electric power to the M-NET centralized control line from the R410A series outdoor
unit
*1
without using a power supply unit for the transmission line, use single-point grounding at the TB7 of that
outdoor unit. *1: Except PUMY model.
Furthermore, when connecting this device to the M-NET indoor control line, use grounding at the TB3 for each
outdoor unit system.
• If the M-NET transmission line of this device is connected to the M-NET indoor control line and the outdoor
unit is down because, for example, the power supply is interrupted for servicing or there is a failure, the DIDO
controller cannot be controlled from the system controller.
• Controlling the ON/OFF remote controller is only possible with channel 1 of a standard terminal block.
• When AE-200E/AE-50E/EW-50E/AG-150A/EB-50GU-J is connected, monitoring control can only be
performed from AE-200E/AE-50E/EW-50E/AG-150A/EB-50GU-J Web or TG-2000A. Monitoring control
cannot be performed from the ON/OFF remote controller
