12 Supplementary Information-2
About Interface adaptors
You can use Interface adaptors to connect equipment that can be turned on and off (fans, room air
conditioners and so on) to the Intelligent Controller.
However, note that the following limitations apply.
For details, refer to the documentation of the equipment or contact your dealer or service provider.
Central control is supported for the following operations only.
• Start/stop
• Remote control prohibition (start/stop only)
Timer settings are supported, but settings other than "start/stop" and "remote control prohibition" are
ignored. Remote control prohibition is possible only when prohibition signal output from the Interface
adaptor has been connected to the equipment. Even in this case, the only operations that can be
prohibited are start and stop.
For each screen from
Alarm display
Alarm details are not shown.
The "C12" code is displayed (meaning Interface adaptor all-unit alarm).
However, this is possible only when a Interface adaptor alarm input signal has been connected.
About air conditioning distribution
1 Indoor unit fan speed data
Total operating times by fan speed are fi xed at high speed. (Units are treated as if they always
operated at high speed, even if the thermostat ON signal is connected to the unit.)
2 Electric heater ON time
Total electric heater ON time is not displayed.
3 Indoor unit capacity values
These cannot be read automatically. Set them as kW values in the "I/D unit settings" screen
(Distribution is not performed if they are not set.)
4 Product types
When connected via Interface adaptors, the system cannot distinguish PAC and GHP units.
You need to set the type as well when you set the indoor unit capacity.
(Refer to "Tenant name/Distribution group" screen
5 This applicable only to simple distribution. No loaded distribution can be made.
As long as it conforms to the contact specifi cations of the Interface adaptors, any type of equipment
can be connected to the Intelligent Controller. However, you should avoid connecting equipment whose
operation can have grave consequences for life or property.
When only one centralized control unit is installed in a system without remote controller, if the centralized
control unit is damaged, the air conditioner(s) may become inoperable, or other troubles may occur. To
avoid this problem, we recommend that you install multiple centralized control units.
