Field Settings from Outdoor Unit SiUS331708EA
115 Field Settings and Test Operation
2.4 Setting Mode 2
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.
4
Existing pipe
connection
The field setting is required based on the field gas piping size and
the field liquid pipe with or without thermal insulation.
When there is no thermal insulation, the airflow rate of the
operating indoor unit may decrease due to protection.
5 Indoor unit forced fan H Allows forced operation of indoor fan while unit is stopped. (H tap)
6
Indoor unit forced
operation
Allows forced operation of indoor unit.
7 SC adjustment Subcooling adjustment for refrigerant addition.
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 /
demand setting
Reception of external low noise or demand signal
13 AIRNET address Set address for AIRNET.
14
Switch over ambient
setting
When the temperature is lower than the set ambient temperature,
operate the gas furnace instead of heat pump heat.
(Gas furnace operation requiring signal : ON)
15
Switch over ambient
setting
(Release differential)
Differential temperature for release of "Switch over ambient
setting".
16
Setting of heat pump
lockout 1
Make this setting for heat pump lockout.
19
Emergency automatic
heat pump lockout Heat pump is automatically locked out in the event of a system
failure.
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 low noise
level
Sets low noise level when the low noise signal is received.
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 PCB.
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 night-time low noise operation.
30 Demand setting 1
Changes target value of power consumption when demand control
1 is received.
32
Constant demand
setting
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.)
37
Setting of heat pump
lockout 2
Make this setting for heat pump lockout.
41 Cooling comfort setting Selects comfort level of VRT cooling.
The numbers in the No. column represent the number of times to press the SET
(BS2) button.
