8-2-22. Communication error in tracking
Check by comparing of set values of installed
numbers of indoor units on outdoor unit
PCB with actual installed numbers.
Press reset key (K3) on the outdoor unit
PCB to check the display part and then
check the indoor unit numbers with
response to the tracking.
Remove the communication cable from
outdoor unit to indoor unit and measure
two lines of outdoor unit side with scope?
Is there no response of indoor unit
on display part during tracking?
Reconnect the communication line from
outdoor unit to indoor unit and check the
communication line changing (it must be
not change F1 and F2) and then reconnect
one by one to locate the indoor unit
obstructing the communication,
and then replace the PCB.
The voltage between
two lines is wave of DC±0.7V as
shown in the following:
Is the numbers of indoor
units installed same as those of set values on
the setting switch?
Set the installed numbers of indoor
units on outdoor unit correctly and then press
reset key (K3) on the outdoor
unit PCB to track indoor units again.
Locate the indoor unit having the
communication error after 2 minute and check
the duplication of PCB address.
(If the address of indoor unit is
duplicated, communication error occurs.)
- In such a case the communication error
appears from more than 2 sets
of indoor units whose addresses
are wrong.
If there is no trouble in the address, replace the
PCB after checking the communication cable.
Check the outdoor unit communication
cable of PCB and replace the PCB.
