Interface adaptors for on/off control
Using interface adaptors for on/off control enables you to connect devices (ventilation fans, room air conditioners, etc.) to turn on or off.
There are the following limitations you should be aware of, however.
Contact the place of purchase or your servicing agent for details.
Items that can be centrally
controlled
Centralised control is possible only with the following items:
y
ON/OFF
y
Remote controller prohibition (only prohibiting “ON/OFF”)
You can also make timer settings, but settings other than “ON/OFF” and “remote controller prohibition” will be invalid.
“Remote controller prohibition” is only for when local prohibition signal output is connected from the interface adaptor to the device.
Alarm display
“C12” (interface adaptor batch alarm) is displayed, but no details are displayed. (However, only when the alarm signal input is
connected to the interface adaptor)
Air conditioning distributing
Indoor unit fan speed data
The cumulative operating hours by fan speed will be fixed to “Mid.”. Even when the
thermostat ON signal input is connected to the interface adaptor, the cumulative operating
hours will be counted as fixed to “Mid.”.
ON hours for electric heater
The cumulative ON time for electric heaters is not displayed.
Indoor unit performance fixed values
As these are not identified automatically, set the performance fixed capacity values (kW)
in the “Edit unit settings” dialogue (P.143).
Distribution methodology
Only time distribution is supported.
Note
y
If a device meets the contact specifications as an interface adapter for on/off control, you can control this unit from any device, but avoid using
for devices that have an important influence over life, property, etc.
y
After starting distribution operation, if you change the address of an indoor unit or switch the address of an indoor unit with another, for
example, distribution calculations will be inaccurate, and other problems may occur so care should be taken.
