•The relays and extension cables are field supplied.
•Use a no-voltage contact and minute load relay (minimum application load 5VDC-1mA).
•The length of the connection cable extension should not exceed 10 m (32 ft). (Use a cable of 0.3 mm² (22AWG) or thicker.)
•Insulate the area with vinyl tape where the controller cable and the extension cable are connected.
•Insulate the end of unused lead wires with tape.
2. External signal output
*To use external output, an external input/output adapter (PAC-YT41HAA; sold separately) is required.
Requires a separate external power source.
(1) External signal output (CN3)
Operation signal will be output when one or more air conditioning units are in operation, and error signal will be output when one or
more units are in error.
The On-signal will be output even during an error.

Operating coil
Rated voltage:12 VDC or 24 VDC
Power consumption: 0.9 W or below
(*1) Select a power supply suitable for the relays used. (12 VDC or 24 VDC)
(*2) Use a diode at each end of the relay coil.
• Each element will turn on when an error occurs during operation.
• The maximum length of extension cable is 10 m (32 ft). (Use a cable of
0.3 mm² (22AWG) or thicker.)
• Insulate the area with vinyl tape where the controller cable and the
extension cable are connected.
• Relays, lamps, diode, extension cables are field-supplied.
●
To connect cables from an external input/output adapter to connectors CN2 and CN3 on the controller, cut out the appropriate
knockout holes on the controller with nippers.
After connecting the cables to the connectors, hold the cables in place with a piece of tape included with the external
input/output adapter (PAC-YT41HAA).
●
Use caution not to damage the circuit board with the nippers or other tools when cutting out knockout holes.
