2. Processes and functions
3P plug (black): Terminal plug for the communications line
 At the time of shipment from the factory, the shor t-circuiting socket (2P, black) is
installed between pins 1 and 2 on the terminal plug (terminal = yes).
 When central control is used for multiple systems, leave the short-circuiting socket in
place only on the outdoor unit with a system address of 1. At all other outdoor units
(other than unit No. 1), move the short-circuiting socket to between 2 and 3 (terminal =
no). If multiple short-circuiting sockets remain in place during central control, a com-
munications failure will occur.
 In the case of a single system only (system address = 0), do not remove the short-
circuiting socket. (Alarm E04 will occur.)
2P plug (white): Enables operation in quiet mode.
 The outdoor unit fan and compressor frequencies are subject to limits during operation.
 Low-noise operation is enabled when the relay is turned ON.
Outdoor unit control PCB
Note 1:The maximum length of the wiring between the outdoor unit PCB and the relay is
2 m.
 Lead wire with 2P plug (special-order part: WIRE K/ CV6231612098)
 Relay, field supply, contact input specifications: DC 5 V, 0.5 mA (Recommended relay:
Fuji Electric HH62SW, compatible with micro contacts)
