Judgment and measures
ëRemote controller LCD display OFF (Disconnection)
ëCentral remote controller [97] check code
ëInter-unit wire check, correction of miswiring
Check outdoor P.C. board. Correct wiring of P.C. board.
2. When outdoor unit normally operates
Check P.C. board (Indoor receiving / Outdoor sending).
1. Check whether remote controller connection (Group/Individual)
was changed or not after power supply turned on
(Finish of group construction/Address check).
* If group construction and address are not normal when the
power has been turned on, the mode automatically shifts to
address setup mode. (Resetting of address)
1. Set indoor capacity (CODE No. (DN) = 11)
1. Check outside devices.
2. Check indoor P.C. board.
1. Trouble of drain pump
2. Clogging of drain pump
3. Check float switch.
4.
5. Check Application control kit of indoor unit
Check indoor P.C. board.
1. Position detection error
2. Over-current protective circuit of indoor fan driving unit operated.
3. Indoor fan locked.
4. Check indoor P.C. board.
1. Check 4-way valve.
2. Check PMV
3. Check indoor heat exchanger (TC/TCJ).
4. Check indoor P.C. board.
1. Judge follower unit while header unit is [E03], [L03], [L07] or [L08].
2. Check indoor P.C. board.
1. Check indoor heat exchanger temp. sensor (TCJ).
2. Check indoor P.C. board.
1. Check indoor heat exchanger temp. sensor (TC).
2. Check indoor P.C. board.
1. Check indoor heat exchanger temp. sensor (TA)
TT .
2. Check indoor P.C. board.
1. Check indoor EEPROM. (including socket insertion)
2. Check indoor P.C. board.
1. Check indoor P.C. board.
1. Check power supply / communication harness
2. Check indoor P.C. board
E18
Regular communication error between
indoor master and follower units and
between main and sub units
Displayed when
error is detected
1. Check remote controller wiring.
2. Check indoor power supply wiring.
3. Check indoor P.C. board.
After heating operation has started,
indoor heat exchangers temp. is
down.
1. Outdoor unit does not completely operate.
1. Check cables of remote controller and communication adapters.
