Capacity
input range
Controlled by external controller and EEV closed by making the capacity input 0% in cooling mode.
Thermostat OFF
EEV slightly opened when the Compressor operating in heating mode.
conditions
Operation Controlled by external controller, input to DX Kit external input terminal
(ON/OFFMode/ *Operation from FGL controller is disabled.
Set temperature (Only monitoring is possible)
When error When fanmotor locked or another error was generated at the external equipment, the refrigerant cycle is
generated at stopped by inputting an error signal to the DX Kit external input terminal. (EEV is Closed)
external equipment
Fan control
Control is perfomed by external equipment, but when you want to stop the fan during defrosting, use the
defrost signal that is output from the DX Kit external output terminal.
