* This figure omits the power supply line and only shows the transmission line.
<Restrictions>
Maximum of 50 units (50 channels) per AG-150A/GB-50ADA
However, the number of units that can be connected to a AG-150A/GB-50ADA 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 AG-150A/GB-50ADA.
For example, 5 contacts connected to the DIDO controller are calculated as the equivalent of 5 indoor units connected to
AG-150A/GB-50ADA.
• 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
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.
NOTE • 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.
• DIDO controller can only be monitored or performed from AG-150A LCD, AG-150A/GB-50ADA Web browser
and TG-2000A.
• When AG-150A/GB-50ADA is connected, monitoring control can only be performed from AG-150A,GB-50ADA
Web or TG-2000A. Monitoring control cannot be performed from the ON/OFF remote controller.
