NOTE
Auxiliary relays (locally procured) must be connected to output signal function wirings to allow connection to the
hot water module output signal functions. The maximum current output signal, from each of the output signal
function wirings, is 16 mA. Please ensure the rated current of the relay coil is less than 16 mA to avoid damage to
the hot water module P.C. board.

Output function wire
CAUTION
Output signal functions are separated from primary basic insulation.
• To prevent noise trouble, use 2-core shield wire.
• Determine the wire length between the hot water module output signal function terminal block and the relay up
to 2 m.
• Locally procure and install protective devices such as the heater and pump.
 Address setup
Set up the addresses as per the Installation Manual supplied with the outdoor unit.
CAUTION
Set the DIP switch 4 of SW09 on the P.C. board of the header outdoor
unit "ON". (Factory default is "OFF")
VRF system will be stopped to avoid water freezing when the power
supply is disconnected.

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.
 Basic procedure for changing
settings
Change the settings while the hot water module is not
working. (Stop the hot water module before making
settings.)
CAUTION
Set only the CODE No. shown in
the following table: Do NOT set
any other CODE No.
If a CODE No. not listed is set, it
may not be possible to operate
the hot water module or other
trouble with the product may
result.
 Group control
In a group control, a remote controller can control up to
maximum 8 units.
• The wired remote controller only can control a group
control. The wireless remote controller is unavailable
for this control.
• For wiring procedure and wires of the individual line
(Identical refrigerant line) system, refer to "Electrical
Connection" in this Manual.
• Wiring between indoor units in a group is performed
in the following procedure.
• Connect the hot water modules by connecting the
remote controller wires from the remote controller
terminal blocks (A, B) of the hot water module
connected with a remote controller to the remote
controller terminal blocks (A, B) of the other hot
water modules. (Non-polarity)
• For address setup, refer to the Installation Manual
attached to the outdoor unit.
 Remote controller sensor
CAUTION
Remote controller sensor cannot
be used for the hot water module.
Remote controller sensor has no
function when remote controller
is connected to the hot water
module.
