Setting item
Description
0
Digital pressure
gauge kit display
Used to make setting of contents to display on the digital
pressure gauges (e.g. pressure sensors and temperature
sensors)
1
Cool/heat unified
address
Sets address for cool/heat unified operation.
2
Low noise/demand
address
Address for low noise/demand operation
3
Test operation
settings
Used to conduct test operation without making changes to
the PC board and replacing the refrigerant, after the
completion of maintenance.
5
Indoor unit forced
fan H
Allows forced operation of indoor unit fan while unit is
stopped. (H tap)
6
Indoor unit forced
operation
Allows forced operation of indoor unit.
(Forced thermostat ON)
8
Te setting
Target evaporation temperature for cooling
9
Tc setting
Target condensation temperature for heating
10
Defrost changeover
setting
Changes the temperature condition for defrost and sets to
quick defrost or slow defrost.
11
Sequential
operation setting
Sets sequential operation
(Factory set to ON)
12
External low noise
setting / Demand
setting
Reception of external low noise or demand signal
13
AIRNET address
Set address for AIRNET.
18
High static pressure
setting
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.
20
Additional
refrigerant charge
operation setting
Carries out additional refrigerant charge operation.
21
Refrigerant recovery/
vacuuming mode
setting
Sets to refrigerant recovery or vacuuming mode.
22
Night-time low
noise setting
Sets automatic nighttime low noise operation in a simple way.
The operating time is based on “Starting set” and “Ending
set”.
24
ENECUT test
operation
Used to forcibly turn ON the ENECUT. (Be noted that the
ENECUT is only functional with outdoor unit in the stopped
state - Japanese domestic model only.)
25
Setting of external
low noise level
Sets low noise level when the low noise signal is input from
outside.
26
Night-time low
noise operation
start setting
Sets starting time of nighttime low noise operation.
(Night-time low noise setting is also required.)
27
Night-time low
noise operation end
setting
Sets ending time of nighttime low noise operation.
(Night-time low noise setting is also required.)
28
Power transistor
check mode
∗
Check after
disconnection of
compressor wires
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 PC board.
29
Capacity
precedence setting
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.
30
Demand setting 1
Changes target value of power consumption when demand
control 1 is input.
32
Normal demand
setting
Normally enables demand control 1 without external input.
(Effective to prevent a problem caused by a circuit breaker
of small capacity shutting down due to large load.)
