Confirming The Numbers And Positions Of Indoor Units - Toshiba MMY-MAP0804HT8-E Service Manual

NOTE
(1) When setting the line address from the remote controller, do not use addresses 29 and 30.
Addresses 29 and 30 cannot be set up on the outdoor unit. If they are incorrectly used, the code "E04" (indoor/outdoor
communication circuit error) is output.
(2) When manual address setup has been done from a remote controller, and central control over refrigerant lines is to be done,
setup the header unit of each line as follows:
• Using SW13 and SW14 on the interface PC board of the header unit of each line, setup the line address for each
line.
• Except for the line with the smallest line address number, set SW03-bit 2 to "off" for the interface PC board of the
header unit of lines connected to the same central control (put the resistance of the end terminals of the central
control line, indoors and outdoors, into one).
• Connect the relay connector between U1/U2 and U3/U4 of the header unit for each refrigerant line.
• After that, set up the central control address. (For central control address setup, refer to the installation manual of
the central control devices.)
