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

- Type of input signal
SW_STEP
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

Input_LNO : Low Noise Operation
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

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.
