7. AUTO RESTART FUNCTION

By setting the dip switch SW1-10 to ON for PK12 and cutting to the jumper wire J1-10 for PK18/24/30/36, the air condition-
er can be started/stopped by power supply ON/OFF.
If the air conditioner is OFF before the power failure, it will not start operation by power restore.
•This function is mainly to emergency performance when the power supply stops temporarily. Therefore, since the protec-
tion function (for example, crank case heater and prevention from restarting in 3 minutes, etc.) of the device is not operat-
ed, this function should not be used mostly.
