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 PC board 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.
(Forced thermostat ON)
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 set to ON)
Reception of external low noise or demand signal
Set address for AIRNET.
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.
Carries out additional refrigerant charge operation.
Sets to refrigerant recovery or vacuuming mode.
Sets automatic nighttime low noise operation in a simple way.
The operating time is based on "Starting set" and "Ending
set".
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.)
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 PC board.
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 without external input.
(Effective to prevent a problem caused by a circuit breaker
of small capacity shutting down due to large load.)
