Power Proportional Distribution (PPD)
(2) A group address is not set to a slave indoor unit with remote controller group.
iTM cannot control slave indoor units (Indoor units B, D, G, and H in the following figure) in remote controller group. In
general, the setting of a group address is not required for control with a remote controller group. However, it is necessary
to set a group address even to slave indoor units and register it with a power group at PPD setup because a thermo. step
and a suction air temperature for each slave indoor units are required for PPD.
If a group address is not set, electric power is not distributed to the indoor unit.
Electric power is distributed among indoor units whose group addresses are registered.

iTM
Set a group address to B, D, G, and H for PPD.
This setting can be configured in the field
setting No. 30 by remote controller.
The setting method is described in Page 332.
Slave indoor units can not be displayed on the
screen of iTM if they are removed from registration
at a management point because iTM cannot control
the slave indoor units.
Even if slave indoor units are not displayed on the
iTM screen, electric power can be distributed to the
indoor units as long as the group addresses are
registered with a power group at PPD setup.
