GENERAL DESCRIPTION OF SYSTEM
1
• The use of this adaptor allows the system to operate with no system error indication in the event of the interruption of power supply to other indoor units.
(In the case of the following diagram, there will be no error indication on the remote controllers of tenant 1 or tenant 3 or tenant 4 in the event of the
interruption of power supply to tenant 2.)

(1) Connect this adaptor and the PCB of the indoor unit with the
provided relay harness (varying with each indoor unit model).
(2) Connect the 24VAC (±20%) power supply to the X1M terminals of
the adaptor through the normally closed contacts of the relay. Be
sure to contact the relay contacts to both poles of the power
supply so that the positive and negative lines of the power supply
will be turned off simultaneously. A transformer may be used for
the 24VAC power supply provided for each adaptor on the
condition that the transformer has a capacity of 24VA or over.
(3) Provide a relay (with a normally closed contact) between the T1
and T2 terminals of the PCB.
