* This figure omits the power supply line and only shows the transmission line.
*1: The DIDO controller can be connected to G(B)-50A with Ver.3.20 or later.
*2: The DIDO controller can be connected to TG-2000A with Ver.5.10 or later.
For example, 5 contacts connected to the DIDO controller are calculated as the equivalent of 5 indoor units connected to
<Restrictions>
Maximum of 50 units (50 channels) per AG-150A/G(B)-50A, 24 units (24 channels) per GB-24A.
However, the number of units that can be connected to a(n) AG-150A/G(B)-50A is up to 50 (24 for the GB-24A) 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 per contact). One contact connected to this device is
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 without using a power supply unit for the transmission line, use single-point grounding at the TB7 of that
outdoor unit.
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 system remote controller, ON/OFF remote controller, and schedule timer is only possible with
channel 1 of a standard terminal block.
• DIDO controller can only be monitored or performed from AG-150A, AG-150A/G(B)-50A/GB-24A Web
cannot be monitored or performed from the G-50A LCD.
• When AG-150A/G(B)-50A/GB-24A is connected, monitoring control can only be performed from AG-150A,
AG-150A/G(B)-50A/GB-24A Web or TG-2000A. Monitoring control cannot be performed from the system
remote controller (ON/OFF remote controller or schedule timer).
