<Case 3> Automatic Address Setting in Cooling Mode
●
Indoor and outdoor unit power cannot be turned ON for each
system separately.
In the following, automatic setting of indoor unit addresses is
not possible if the compressors are not operating. Therefore
perform this process only after completing all refrigerant
tubing work.
Automatic address setting can be performed during Cooling
operation.
Automatic Address Setting from Outdoor Unit
1 Perform steps 1 – 4 in the same way as for <Case 1>.
2 Turn the indoor and outdoor unit power ON at all systems.
↓
3 To perform automatic address setting in <Cooling mode>,
on the outdoor main unit control PCB in the refrigerant
system where you wish to set the addresses, short-circuit
the mode change 2P pin (CN101). At the same time, short-
circuit the automatic address pin (CN100) for 1 second or
longer, then release it. (Be sure to perform this process for
one system at a time. Automatic address settings cannot
be performed for more than one system at the same time.)
↓
(Communication for automatic address setting begins, the
compressors turn ON, and automatic address setting
in Cooling mode begins.)
(All indoor units operate.)
↓
* To cancel, again short-circuit the automatic
address pin (CN100) for 1 second or longer,
then release it.
The LED that indicates automatic address
setting is in progress turns OFF and the
process is stopped. Be sure to perform
automatic address setting again.
(Automatic address setting is completed when the
compressors stop and LEDs 1 and 2 on the outdoor main
unit control PCB turn OFF.)
↓
4 At the outdoor main unit in the next (different) system,
short-circuit the automatic address pin (CN100) for 1
second or longer, then release it.
↓
(Repeat the same steps to complete automatic address
setting for all units.)
↓
5 Operation from the remote controllers is now possible.
Automatic Address Setting* from the Remote Controller
* Automatic address setting in Cooling mode cannot be done
from the remote controller.
Selecting each refrigerant system individually for automatic
address setting
---Automatic address setting for each system: Item code "A1"
●
Press the remote controller timer time
button at the same time. (Press and hold for 4 seconds or
longer.)
●
Next, press either the temperature setting
button.
(Check that the item code is "A1.")
●
Use either the
No. to perform automatic address setting.
●
Then press the
(Automatic address setting for one refrigerant system
begins.)
(When automatic address setting for one system is
completed, the system returns to normal stopped status.)
<Approximately 4 – 5 minutes is required.>
(During automatic address setting, "SETTING" is displayed
on the remote controller. This message disappears when
automatic address setting is completed.)
●
Repeat the same steps to perform automatic address setting
for each successive system.
