ENGLISH
③
Setting of Rotary switch :
Use the Rotary Switch to set a control step
for contact signal input : The type of input
signal and control step can be set using
SW104. This function is for demand control
to reduce power Consumption. Set the
control mode what you want According to
the table as below.
- Type of input signal
SW_STEP
Input signal
0, 1, 2, 3, 4, 5, 6, 7
Contact signal input
C, D, E
Analog input signal
CAUTION
Do not change a command too quickly.
Keep the command 30 seconds at least,
otherwise it will cause a damage to out-
door unit.
• Operation rate condition :
- Cooling : Outdoor 35 °C, Indoor 27 °C
- Heating : Outdoor 7 °C, Indoor 20 °C
• The tolerance of the operation rate can
be cause by combination of outdoor
unit, operating condition, installation cir-
cumstance.
• When operation rate is 100%, Target
Evaporating Temp. and Target
Condensing Temp. can be changed by
installation option. (Refer to product data
book)

①
Dry contact input part
Connect Non Voltage contact signal for
demand control (3 step)
* Priority setting
Using ‘Priority setting’ contact signal,
set the priority of command.
(External command from DDC Vs
Command from LG central controller.)
- Close : Central controller has priority
to external signal.
- Open : External signal has priority to
central controller.
②
Analog input part
Connect Analog input signal for demand
control (10 step)
③
Analog output part
Connect Analog output signal for con-
trolling third party devices.
Ex) Valve actuator for variable water
flow. Damper actuator for Low Ambient
Kit
④
Digital output part
Connect status display devices.
CAUTION
Power must be turned on after the prod-
uct is wired completely.
