Field Setting from Outdoor Unit
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. (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 setting to ON)
Reception of external low noise or demand signal
Set the address for AIRNET.
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.)
If the compress has a failure, used to prohibit the
operation of STD compressor and to conduct emergency
operation of the system with other compressor.
Carries out additional refrigerant charging operation.
Sets to refrigerant recovery or vacuuming mode.
Sets automatic low night noise operation in a simple way.
The operating time is based on "Starting set" and "Ending
set".
Sets low noise level when the low noise signal is input
from outside.
Sets starting time of low night noise operation.
(Low night noise setting is also required.)
Sets ending time of low night noise operation.
(Low night 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 low night 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 that circuit breaker
of small capacity is shut down due to large load.)
