Judgment and measures
Power supply trouble of remote controller, Indoor
EEPROM trouble
1.Check remote controller inter-unit wiring.
2.Check remote controller.
3.Check indoor power wiring.
4.Check indoor P.C. board.
5.Check indoor EEPROM.
(including socket insertion)
→ Automatic address repeating phenomenon
generates.
Receiving trouble from remote controller
1.Check remote controller inter-unit wiring.
2.Check remote controller.
3.Check indoor power wiring.
4.Check indoor P.C. board.
Sending trouble of remote controller
1.Check sending circuit inside of remote controller.
→ Replace remote controller.
1.In 2-remote controllers (including wireless), there
are multiple header units.
Check that there are 1 master remote controller
and other sub remote controllers.
1.Check setting of central control system network
address. ("1 : 1 Model" Connection Interface

2.Check "1 : 1 Model" Connection Interface P.C.
board.
1.Check communication wire / miswiring
2.Check communication (U3, U4 terminals)
3.Check "1 : 1 Model" Connection Interface P.C.
board.
4.Check central controller (such as central control
remote controller, etc.)
5.Check terminal resistance. (TCC-LINK)
Check the check code of the corresponding unit from
remote controller.
