11.1 About standby electricity saving function

The standby electricity saving function:

▪

turns OFF the power supply to the outdoor unit and,

▪

turns ON the standby electricity saving mode on the indoor unit.

The standby electricity saving function works with following units:

3AMXM52

FTXM, FTXP, FTXJ, FVXM

If another indoor unit is used, the connector for standby electric saving MUST be
plugged in.

The standby electricity saving function is turned OFF before shipping.

11.1.1 To turn ON standby electricity saving function

Prerequisite:

The main power supply MUST be turned OFF.

Remove the service cover.

Disconnect the selective standby electricity saving connector.
