4. Step 1:
Selection of Air Conditioning Equipment
In order to construct the system, air conditioning equipment should be selected firstly.
This chapter introduces the air conditioners that can be controlled with G-50A and various limitations
applicable. For the detail of air conditioning equipment, please refer to the manual of the relating air
conditioner.
4.1 Limitations
4.1.1 Limitations on system composition
Table 4-1 Limitations on system composition
Item
Controllable indoor unit quantity with 1
set of G-50A
Connecting quantity of G-50A
Controlling quantity of integrated
software
Detail
1 set of G-50A can control indoor unit up to 50 sets. Lossnay if
connected should be included in this figure.
As G-50A will be the upper system controller inside a centralized system, the
quantity of G-50A connectable with the centralized system counts for 1 set only.
The quantity of G-50A that can be controlled with the integrated software is 40
sets. This can be converted into air conditioner indoor unit of 2000 sets maximum.
Limitation
50 sets
1 set
40 sets of
G-50A

4.1.2 Limitation on group setting
Table 4-2 Limitation on group setting
Item
Connectable remote controller within 1
group
Connectable indoor unit within 1 group
Registration of system controller and
local remote controller within 1 group
Groups on 1 floor
Detail
Except for the remote controllers of M-NET system, group setting is not necessary for
this unit. (ME and MA remote controllers can not be used together within a same group.)
The indoor unit, K-control indoor unit, A-control indoor unit and Lossnay
can not be grouped.
The setting that runs over G-50A can not be applied.
Not including the quantity of G-50A
On the screen of whole building display, 50 groups maximum can be
configured and displayed per floor. (At displaying of floor screen, it may
not be displayed due to the floor diagram.)
Limitation
Up to 2 sets
Up to 16 sets
Up to 4 sets
Up to 50 groups

*1 An adaptor is required separately.
A control slim type: M-NET connection adaptor, K control type: K transfer converter, Room air conditioner: M-NET control interface.
*2 The indoor units before free plan are not for electricity division accounting.
(They are according to electricity amount pulse count method (direct reading method).)
*3 Electric power division accounting is calculated in the same method as the indoor units of City Multi Y.
Without consideration of night electric charge, but with the use operation parameters of indoor units as reference, electric power
division accounting is calculated.
*4 This can be applied in the case of use by IC properties.
*5 Application by FAN operation is possible.
*6 Performance save control to outdoor units are not available.
*7 Thermo OFF control to indoor units is not available, therefore ventilation operation control is carried out.
*8 Only whether the set temperature control or the stop control can be made to RAC.
*9 Only the stop control is valid.
*10 In the case of use by IC properties, energy saving control similar to free plan indoor units can be carried out.
With FU properties, same control as free plan LOSSNAY is available.
