1.
Error occurrence on some IC
Same remedy as that for

unit
(1)
Same cause as that for system with one
outdoor unit
2.
Error occurrence on all IC in the system
with one outdoor unit
1) Check the LED display
for troubleshooting on the
outdoor unit.
(1)
Total capacity error (7100)
If an error is found,
check the check code
definition, and correct
the error.
If no error is found,
check 2).
(2)
Capacity code error (7101)
(3)
Error in the number of connected units
(7102)
(4)
Address setting error (7105)
(5)
Disconnection or short circuit of the trans-
mission line for the outdoor unit on the ter-
minal block for centralized control line
connection (TB7)
2) Check (5) - (7) on the left.
(6)
Turn off the power source of the outdoor
unit
(7)
Malfunction of electrical system for the
outdoor unit
3.
Error occurrence on all IC
Check voltage of the
transmission line for cen-
tralized control.
20V or more: Check (1)
and (2) on the left.
Less than 20V: Check
(3) on the left.
(1)
Same causes as (1) - (7) described in 2.
(2)
The male power supply connectors on 2
or more outdoor units are connected to
the female power supply switch connector
(CN40) for the transmission line for cen-
tralized control.
(3)
Disconnection or shutdown of the power
source of the power supply unit for trans-
mission line
(4)
System controller (MELANS) malfunction
