SiBE341027 Field Setting from Outdoor Unit
Test Operation 73
No. Setting item Description
0
Digital pressure
gauge kit display
Used to make setting of contents to display on the digital
pressure gauges (e.g. pressure sensors and temperature
sensors)
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. (Forced thermostat
ON)
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
(Factory setting to ON)
12
External low noise
setting / Demand
setting
Reception of external low noise or demand signal
13
Setting of AIRNET
address
Set the address for AIRNET.
16 Setting of hot water
Make this setting to conduct heating operation with hot
water heater.
18
High static pressure
setting
Make this setting in the case of operating in high static
pressure mode with diffuser duct mounted.
(In order to mount the diffuser duct, remove the cover
from the outdoor unit fan.)
19
Emergency
operation
If the compress has a failure, used to prohibit the
operation of STD compressor and to conduct emergency
operation of the system with other compressor.
20
Additional
refrigerant charging
operation setting
Carries out additional refrigerant charging operation.
21
Refrigerant recovery/
vacuuming mode
setting
Sets to refrigerant recovery or vacuuming mode.
22
Low night noise
setting
Sets automatic low night 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
Low night noise
operation start
setting
Sets starting time of low night noise operation.
(Low night noise setting is also required.)
27
Low night noise
operation end
setting
Sets ending time of low night noise operation.
(Low night 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 PCB.
29
Capacity priority
setting
If the capacity control is required, the low noise control is
automatically released by this setting during carrying out
low noise operation and low night 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.)
