Field Setting SiEN18-622
156 Test Operation
No. Setting item Description
1
Cool/heat unified
address
Sets address for cool/heat unified operation.
2
Low noise/demand
address
Address for low noise/demand operation
3
Test operation
settings
Used to conduct test operation without making changes
to the PCB and replacing the refrigerant, after the
completion of maintenance.
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.
12
External low noise
setting / Demand
setting
Reception of external low noise or demand signal
13 AIRNET address Set address for AIRNET.
16 Setting of hot water
Make this setting to conduct heating operation with hot
water heater.
20
Additional
refrigerant charge
operation setting
Carries out additional refrigerant charge operation.
21
Refrigerant
recovery /
vacuuming mode
setting
Sets to refrigerant recovery or vacuuming 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
Setting of external
low noise level Sets low noise level when the low noise signal is input
from outside.
26
Night-time low
noise operation
start setting
Sets starting time of nighttime low noise operation.
(Night-time low noise setting is also required.)
27
Night-time low
noise operation end
setting
Sets ending time of nighttime low noise operation.
(Night-time 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.
