REQUIREMENT
When the hot water module is used for the first time, it will
take some moments after the power has been turned on
before the remote controller becomes available for
operations: This is normal and is not indicative of trouble.
• Concerning the automatic addresses (The automatic
addresses are set up by performing operations on
the outdoor interface circuit board.)
While the automatic addresses are being set up, no
remote controller operations can be performed.
Setup takes up to 10 minutes (usually about 5
minutes).
• When the power is turned on after automatic address
setup
It takes up to 10 minutes (usually about 3 minutes)
for the outdoor unit to start operating after the power
has been turned on.
Before the hot water module was shipped from the factory, all
units are set to [STANDARD] (factory default). If necessary,
change the indoor unit (including hot water module) settings.
The settings are changed by operating the wired remote
controller.
* The settings cannot be changed using only a
wireless remote controller, simple remote controller
or group control remote controller by itself so install
a wired remote controller separately as well.

working.
(Stop the hot water module before making
settings.)
