When using the air conditioner with central priority, remove the cover of interface adapter,
and select "CENTRAL" side of the select switch (SW 1) at near the center of P.C. board.
(Relays are used for central indication in order to prevent
malfunction by surge absorber.)
• Selecting of Central priority/Last-push priority
• Wiring method
The select switch has been previously set to LAST-PUSH side on shipment
from the factory.
• Notes on connecting relays

(CAUTION)
Be sure to turn off the power supply of
interface adapter before selecting one
side on the select switch.
(Note)
Mount surge absorbers to both ends of the relay coil.
Use a surge absorber of which voltage tightness is 350V AC/500V
DC or more.
(Note)
Mount diodes to the both ends of the relay coil.
Select a diode of which back voltage tightness is 10 times or more
of the use voltage, and forward current is more than the load
current.
