6608
No response
When no response command
is returned although acknowl-
edgement (ACK) is received
after transmission, an error is
detected.
When the data is transmitted
10 times in a row with 3 sec-
onds interval, an error is de-
tected on the transmission
side.
Note:The address/attribute
appeared on the display
on the remote controller
indicates the controller
where an error oc-
curred.
(1) The transmission line work is
performed while the power is on,
the transmitted data will collide,
and the wave shape will be
changed.
(2) The transmission is sent and re-
ceived repeatedly due to noise.
(3) Decrease of transmission line
voltage/signal by exceeding ac-
ceptable range of transmission
wiring.
Farthest :
200m [656ft] or less
Remote controller wiring:
12m [39ft] or less
(4) The transmission line voltage/
signal is decreased due to erro-
neous sizing of transmission
line.
Wire diameter: 1.25mm

[AWG16] or more
1) When an error occurs at commission-
ing
Turn off the power source of the heat
source unit, indoor unit, and LOSS-
NAY for 5 or more minutes, and turn
them on again.
-> When they return to normal opera-
tion, the cause of the error is the
transmission line work performed
with the power on.
-> If an error occurs again, check the
cause 2).
2) Check (3) and (4) on the left.
-> If the cause is found, correct it.
-> If no cause is found, check 3).
3) Check transmission wave shape/
noise on trans-mission line by follow-
ing <Investigation method of transmis-
sion wave shape/noise>.
Noise is the most possible cause of
the error "6608".
