operated to prevent the room temperature dropping below
50°. When normal operation starts, the minimum heat opera-
tion stops.

ECONOMY OPERATION
Operation of the indoor units in economy mode, which saves a
little power, reduces energy use more than normal operation.
If the room is not cooled (or heated) well during economy op-
eration, select normal operation.

While this function is selected, all indoor units start the mini-
mum heat operation when all the indoor units are stopped by
operation of the [On/Off button] on the Central remote control-
ler.
