2.3 Restrictions
The following restrictions apply to the TG-2000A application.
(1) System configuration limits
Use TG-2000A with the versions described in this manual with AG-150 Ver. 1.0* or later or with
G-50A Ver. 3.22 or later.
Number of units Notes
AG-150A/G-50A Max. 40 units
AG-150A Ver.1.0*
G-50A Ver. 2.10 or later *1,2,3,4,5,6,8,9,10,11
Indoor unit Max. 2000 units (including all IC,
KIC, AIC, LC, FU, MCT, MCP
and DC *12)
Max. 50 units/
(AG-150/G-50A) *12,13
General equipment
(PLC)
Up to 640 units (including 20
PLCs for general equipment)
Max. 32 units/PLC
General equipment
(IC I/O signal)
Up to 2000 units *7 Max. 350 units/(AG-150/G-50A)
PI controller (MCT)
*14
UP to 40 units *13
(Up to 160 meters)
Max. 5 units/(AG-150/G-50A)
Max. 40 units/TG-2000A

*1: The version can be confirmed with the method explained in section 8.6.3.
*2: Use G-50A Ver. 2.31 or later to use the power apportioning billing function.
*3: Use G-50A Ver. 2.50 or later to use the energy saving/peak cut function.
*4: Only 32 units each can be connected for the PLC for general equipment. These are the general equipment No.
1**-1 to 32 listed in Section 8.9.4. 33 to 100 cannot be used due to restrictions for the PLC for general
equipment.
*5: When G-50A is more than Ver.2.50, TG-2000A of Ver.2.00 does not operate.
*6: Use G-50A Ver. 2.60 or later when using the night mode or auto change over function.
*7: Up to 350 general equipment units can be connected to the IC I/O signal with each G-50A. However, the
integrated software TG-2000A can control only up to 2000 general equipment units connected to the IC I/O
signal. Use G-50A Ver.2.70 or later when using the IC I/O signal function.
*8: The combination use of TG-2000A Ver4.70 and G-50A Ver2.71 expands the set temperature range limit
function (such as the upper limit of the set temperature for the Cool (Dry) mode, the lower limit for the Heat
mode and the upper and the lower limit for the Auto mode).
*9 The combination of TG-2000A Ver.4.80 and G-50A Ver.2.51 support a charge apportioning billing method of
A-control and K-control units.
*10 When using G-50A initial setting Web, the combination of G-50A Ver.2.80 or later and TG-2000A Ver.4.80 or
later must be used.
*11 When using the 1ºF temperature setting function, use the combination of G-50A Ver.3.00 or later and
TG-2000A Ver.5.00 or later. The indoor unit supporting the 1ºF temperature setting function is also required.
*12 1 contact point for DIDO Controller is converted to 1 unit. Up to 50 units are connectable to each AG-150A/G-50A.
*13 DIDO Controller, AI Controller and PI Controller are supported by G-50A Ver.3.20 and TG-2000A Ver.5.10 or later.
*14 Only either PLC or PI Controller can be connected for meter connection. Both cannot be connected at the same time.
(2) Group setting restrictions
Item Restrictions Note
Remote controls 2 per group * Other remote controls besides M-NET type will not work *1
Number of indoor units
connected to a group
1 to 16
* IC, AIC, KIC, LC and DC cannot be used within the same
group. It is not possible for group settings to span
AG-150A/G-50A *2,3
Number of SC and RC
connected to a group
4 per group * The number of AG-150A/G-50A is not included
Groups per floor
Max. 50 groups
per floor
Up to 50 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.
*3 Set units with different models or functions in another group.
