Connecting to External Equipment
• Non-voltage contact "a"
• Keep the external I/O wiring lengths of 20 meters or less. If a longer length is needed, use a Communication Adaptor or relay.
• A voltage of DC5 V (approx. 10 mA) is applied to the contact to detect the input signal.
• Do not apply an external voltage to the input terminal.
• The contact allowable voltage and current for the output signal terminal are max. DC30 V and 0.5 A respectively.
 Turn on all of the indoor units and the outdoor units.
 Turn on the Communication Adaptor (only when
connected), and make the necessary settings.
(See “Installation Instructions” supplied with the
Communication Adaptor.)
 Turn on this unit.

Attach the power switch cover to the original position.
• Do not allow the wirings to be caught.
 Refer to “Quick Reference” and check the following.
• Check if the clock setting and the number of connected
units are correctly displayed.
• Set the central address.
• Make other necessary settings (unit name, area setting,
distribution setting, etc.).
• Check if the indoor unit, etc. can be operated properly
using this unit, and correct statuses are displayed.
 Refer to one of “Service Manual”, “Test Run
Service Manual” and “Technical Data”, and check
the following.
• Make the communication setting with the air conditioner.
• Check and conrm the connection conguration.
Setting and Test Operation
z If the power supply wiring is mistakenly connected
to a terminal board other than the power supply
terminal board, the devices connected to this
controller or this controller will malfunction.
