AUTOMATIC OPERATION

COOLING MODEL : This applies to the COMPACT type SII and MII.
• Depending on the room temperature at the time operation
begins, the operating mode will be switched automatically
as ahown in the accompanying table.
Also, depending on the operating mode, the room tem-
perature setting will cause the "standard" temperature to
be set as shown. The operating mode and standrad ther-
mostat settings are selected automatically when opera-
tion begins.
• When automatic operation is initiated, the fan will run at
very low speed for about one minute while the unit
detects and selects the proper operating mode.
• Once the operating mode has been set, the mode will not
change even if the room temperature changes.
• If the START/STOP button is pressed to recommence
operation within two hours after stopping automatic oper-
ation, the unit will begin operating from the same mode as
before.

very low speed for about one minute while the unit
detects and selects the proper operating mode.
• Once the operating mode has been set, the mode will not
change even if the room temperature changes. However,
during the monitor operation mode, if the room tempera-
ture changes to below 22°C, the mode will automatically
switch to Heat, and when it rises above 24°C the mode
will automatically switch to Dry.
• When in the monitor mode, the fan will operate very slowly.
• If the START/STOP button is pressed to recommence
operation within two hours after stopping automatic oper-
ation, the unit will begin operating from the same mode as
before.
