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 for heat pump lockout.
Heat pump is automatically locked out in the event of a system
failure.
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 received.
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 night-time low noise operation.
Changes target value of power consumption when demand control
1 is received.
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.)
Make this setting for heat pump lockout.
Heat pump would be resumed when the outdoor ambient
temperature is recovered by differential above the heat pump
lockout temperature.
Auxiliary heater is allowed to energize when the ambient
temperature is smaller than the auxiliary heater maximum
allowable temperature.
Auxiliary heater is not allowed to energize when the outdoor
ambient temperature is recovered by differential above the
auxiliary heater maximum allowable temperature.
Heat pump would be locked out when the outdoor ambient
temperature is smaller than the heat pump lockout temperature.
This setting is only effective when heat pump lockout mode has
been set.
