Description
Operates by Standard compressor only when inverter
compressor malfunctions. Temporary operation until the
compressor is replaced. Since the comfortability is extremely
deteriorated, immediately replace the compressor. (This
setting is not applicable to REYQ5M.)
Address for low noise/demand operation
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.
Sets sequential operation
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.
Used to operate system only with inverter compressor when
STD compressor malfunctions. This is a temporary operation
extremely impairing comfortable environment. Therefore,
prompt replacement of the compressor is required.
(This operation, however, is not set with REYQ5M.)
Carries out additional refrigerant charge operation.
Sets to refrigerant collection 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.
(Nighttime low noise setting is also required.)
Sets ending time of nighttime low noise operation. (Nighttime
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 that circuit breaker of small
capacity is shut down due to large load.
