Eco Mode Setting

By connecting an external contact input in the input of mode configuration and external control
adaptor (sold separately), you may control Eco mode setting, limiting compressor operation
load and power consumption.
When Eco mode is set as unavailable (Outdoor unit external control adaptor is
unnecessary)
Eco mode control is unavailable during cooling operation.
When the Eco level of Eco mode control is set as Standard/Low or Eco mode control is
set as unavailable by external control adaptor

1. Connect the external control adaptor and short-circuit the input terminal TeS1 if necessary.
2. Set mode 2-11 (External Eco Setting) to Eco setting by low noise level input or Eco
About Eco Level Setting
The upper limit of Te (target evaporation temperature) and the lower limit of Tc (target
condensation temperature) are changed based on the Eco level.
