Tubing - Panasonic U-4LE1E5 Installation Instructions Manual

<Case 3A> Automatic Address Setting in Heating 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 from Outdoor Unit
1 Perform steps 1 and 2 in the same way as for <Case 2> .
2 Turn the indoor and outdoor unit power ON at all systems.
↓
3 To perform automatic address setting in <Heating mode>,
on the outdoor unit control PCB in the refrigerant system
where you wish to set the addresses, short-circuit the
automatic address pin (CN-A.ADD) for 1 second or longer,
then pull it out.
(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 heating mode begins.)
(All indoor units operate.)
↓
* To cancel, again short-circuit the automatic
address pin (CN-A.ADD) for 1 second or
longer, then pull it out.
The LED that indicates automatic address
setting is in progress turns OFF and the
process is stopped.
(Automatic address setting is completed when the
compressors stop and LEDs 1 and 2 on the outdoor unit
control PCB turn OFF.)
↓
4 At the outdoor unit in the next (different) system, short-
circuit the automatic address pin (CN-A.ADD) for 1 second
or longer, then pull it out.
↓
(Repeat the same steps to complete automatic address
setting for all units.)
↓
5 Operation from the remote controllers is now possible.
* To perform automatic address setting from the remote
controller, perform steps 1 and 2, then use the remote
controller complete automatic address setting.
Refer to "Automatic Address Setting from the Remote
Controller."

<Case 3B> 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 and 2 in the same way as for <Case 2> .
2 Turn the indoor and outdoor unit power ON at all systems.
↓
3 To perform automatic address setting in <Cooling mode>,
on the outdoor unit control PCB in the refrigerant system
where you wish to set the addresses, short-circuit the
cooling side of the mode change 3P pin (CN-MODE). At
the same time, short-circuit the automatic address pin
(CN-A.ADD) for 1 second or longer, then pull it out. (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 (CN-A.ADD) for 1 second or
longer, then pull it out.
The LED that indicates automatic address
setting is in progress turns OFF and the
process is stopped.
(Automatic address setting is completed when the
compressors stop and LEDs 1 and 2 on the outdoor unit
control PCB turn OFF.)
↓
4 At the outdoor unit in the next (different) system, short-
circuit the automatic address pin (CN-A.ADD) for 1 second
or longer, then pull it out.
↓
(Repeat the same steps to complete automatic address
setting for all units.)
↓
5 Operation from the remote controllers is now possible.
* Automatic address setting in Cooling mode cannot be
done from the remote controller.
