Address Setup Procedure - Toshiba MCY-MAP0401HT Installation Manual

REQUIREMENT
• When a group control is performed over multiple
refrigerant systems, be sure to turn on the power
supplies to all of the indoor units connected, so that
the address set-up can be completed correctly.
• If turning on the power for each refrigerant system to
set up the addresses, a header indoor unit must be set
for each system. Therefore, an alarm code "L03"
(Duplicated header indoor units) will be displayed
during in operation after the address setup has been
completed. In this case, change the group address
using the wired remote controller so that only one
header indoor unit is set-up.

◆ Address setup procedure 2

1
Using SW13 and 14 on the interface P.C.
board on the outdoor unit in each system,
set up the system address for each system.
(At shipment the address is set to 1 from the factory)
NOTE
Be careful not to duplicate with any other refrigerant systems
or other line (system) addresses.

Check that the relay connectors between [U1U2] and [U3U4] terminals are come out in all outdoor
units to which the central control is connected. (Factory default : No connection of connector)
3
Turn on power of indoor / outdoor. (In order of indoor → outdoor)

After approx. 1 minute, check that 7-segment display is
on the interface P.C. board.

(Terminator resistors of the wires in the central
control line of indoor / outdoor are unified.)
