Restrictions
Note
Remote controls
2 per group
* Other remote controls besides M -NET
type will not work
Number of indoor units
connected to a group
1 to 16

sible for group settings to span G-50A

Groups per floor
Max. 50 groups per floor Up to 50A groups can be displayed on
one floor of the whole building window.
*1 The ME remote controller and MA remote controller cannot be used together for the same group.
*2 Set the same function unit for the group.
[Symbol]SC: System controller, RC: Remote controller
(3) Block setting
• The block comes in two types, operation block and charge block.
• The operation block is an aggregate of groups, and it is possible to set a different model group
for the same operation block.
• The charge block consists of an aggregate of operation blocks.
(4) Notes on using K control models
When using a K transmission converter (model name: PAC-SC25KA, PAC-SC25KAA(-E)) to manage K
control models, take note of the following. See the documentation provided with the K transmission
converter for more detail.
• The address of the K transmission converter will be the smallest address of the K control model +
200.
• Set the K control model addresses so that they are larger than the M transmission model
addresses.
• When setting a group containing K control models, make the group number the same as the
smallest unit address in the group.
(5) Notes on using A control mode
• Use the A/M NET Adapter (model name: PAC-SF48MA(-E)). Set the group to “Group with only
A control”.
(6) Countermeasure when an error occurs
• Note that each control or function may not operate properly when rebooting (*1) or when a fault
occurs in the centralized Controller G-50A. Since each error is displayed when it occurs, it is
recommended to solve the faults quickly.
*1 Indicates that the system is restarting.
