Description
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.
Reception of external low noise or demand signal
Set address for AIRNET.
Make this setting to conduct heating operation with hot
water heater.
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".
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 without external input.
(Effective to prevent a problem when a circuit breaker of
small capacity is shut down due to large load.)
