b. "Setting mode 2"
Push and hold the MODE (BS1)
button for 5 seconds and set to
"Setting mode 2".
<Selection of setting items>

the LED display to a setting item
shown in the table on the right.
↓
Push the RETURN (BS3) button and
decide the item. (The present setting
condition is blinked.)
<Selection of setting conditions>
Push the SET (BS2) button and set
to the setting condition you want.
↓

Description
Used to make setting of contents to display on the digital
pressure gauges (e.g. pressure sensors and temperature
sensors)
Sets address for cool/heat unified operation.
Address for low noise/demand operation
Used to conduct test operation without making changes
to the PCB and replacing the refrigerant, after the
completion of maintenance.
Allows forced operation of indoor unit fan while unit is
stopped. (H tap)
Allows forced operation of indoor unit.
Target evaporation temperature for cooling
Target condensation temperature for heating
Changes the temperature condition for defrost and sets to
quick defrost or slow defrost.
Sets sequential operation
(Factory setting to ON)
Reception of external low noise or demand signal
Set address for AIRNET.
Make this setting to conduct heating operation with hot
water heater.
Make this setting in the case of operating in high static
pressure mode with diffuser duct mounted.
(In order to mount the diffuser duct, remove the cover
from the outdoor unit fan.)
Used to operate system only with inverter compressor when
STD compressor malfunctions. This is a temporary operation
extremely impairing comfortable environment. Therefore,
prompt replacement of the compressor is required.
(This operation, however, is not set with RXYQ5, 8P.)
Carries out additional refrigerant charge operation.
Sets to refrigerant recovery or vacuuming mode.
Indoor unit Electronic expansion valve
Outdoor unit Part of electronic expansion valve and solenoid valve → Fully open
Sets automatic nighttime low noise operation in a simple way.
The operating time is based on "Starting set" and "Ending set".
Used to forcedly turn ON the ENECUT. (Be noted that the
ENECUT is only functional with outdoor unit in the
stopped state - Japanese domestic model only.)
Sets low noise level when the low noise signal is input
from outside.
Sets starting time of nighttime low noise operation.
(Night-time low noise setting is also required.)
Sets ending time of nighttime low noise operation.
(Night-time low noise setting is also required.)
Used for trouble diagnosis of DC compressor. Since the
waveform of inverter is output without wiring to the
compressor, it is convenient to probe whether the trouble
comes from the compressor or PCB.
If the capacity control is required, the low noise control is
automatically released by this setting during carrying out
low noise operation and nighttime low noise operation.
Changes target value of power consumption when
demand control 1 is input.
Normally enables demand control 1 or 2 without external
input. (Effective to prevent a problem that circuit breaker
of small capacity is shut down due to large load.)
