Field Setting SiUS39-601
84 Test Operation
No. Setting item Description
0
EMG (Emergency
operation 1)
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.
1
Cool/heat unified
address
Sets address for cool/heat unified operation.
2
Low noise/demand
address
Address for low noise/demand operation
5
Indoor unit forced
fan H
Allows forced operation of indoor unit fan while unit is
stopped. (H tap)
6
Indoor unit forced
operation
Allows forced operation of indoor unit.
8 Te setting Target evaporation temperature for cooling
9 Tc setting Target condensation temperature for heating
10
Defrost changeover
setting
Changes the temperature condition for defrost and sets to
quick defrost or slow defrost.
11
Sequential operation
setting
Sets sequential operation
12
External low noise
setting / Demand
setting
Reception of external low noise or demand signal
13 AIRNET address Set address for AIRNET.
18
High static pressure
setting
Make this setting in the case of operating in high static
pressure mode with diffuser duct mounted.
19
Emergency
operation
(STD compressor
operation prohibited)
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.
20
Additional refrigerant
charge operation
setting
Carries out additional refrigerant charge operation.
21
Refrigerant recovery /
vacuuming mode
setting
Sets to refrigerant collection mode.
22
Night-time low noise
setting
Sets automatic nighttime low noise operation in a simple
way.
The operating time is based on “Starting set” and “Ending
set”.
25 Low noise setting
Sets low noise level when the low noise signal is input from
outside.
26
Night-time low noise
control starting
setting
Sets starting time of nighttime low noise operation.
(Nighttime low noise setting is also required.)
27
Night-time low noise
control ending
setting
Sets ending time of nighttime low noise operation.
(Nighttime low noise setting is also required.)
28
Power transistor
check mode
∗Check after
disconnection of
compressor wires
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.
29
Capacity
precedence setting
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.
30 Demand setting 1
Changes target value of power consumption when demand
control 1 is input.
32
Normal demand
setting
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.
