ESIEN05-04 1.3 Functional concept Forced Operating Mode (Emergency Operation) Purpose The table below describes the purpose of the forced operating mode. If... Starting conditions 1 Then... Q R/C is defective Q Indoor PCB is defective Q Outdoor PCB is defective Forced operating mode can be used to go to cooling or heating. In forced operating mode, the compressor is forced to operate until the defective indoor or outdoor PCB is back online.

ESIEN05-04 1.6 Outline Functional concept Restart Standby 1 To prevent the compressor from frequently turning ON and OFF and allow pressure equalization, forced thermostat OFF will be conducted for 3 minutes after compressor stopping (compressor guard timer). 2 Graph Thermostat OFF Compressor Restart standby complete ON OFF Electronic expansion valve OFF Oudoor unit fan 3 Moves to “Stop” or “Starting control” after completion of “Restart standby”.
PAGE 148
Functional concept 1 1.7 ESIEN05-04 Automatic Restart Purpose The purpose of the auto-restart function is to automatically resume the same operating mode as when the unit was operating when the power supply is restored after a power failure. Do not use the "Automatic Restart" function to daily start/stop the unit. 2 Precautions when turning OFF power 3 Q When you have to turn OFF the power supply in order to carry out maintenance, make sure to turn the remote control's ON/OFF switch OFF firstly.
