during cool operation or dry operation, the compressor
is stopped.

7-1 24-HOUR PROGRAMMABLE ON/OFF TIMER
ON-TIMER or OFF-TIMER can be independently
programmed. When the unit operates during one
hour after the OFF-time is set, thermostat setting
is automatically shifted (+1˚C in cool operation
and dry operation, -3˚C in heat operation, but,
16˚C set temperature at the lowest).
When the ON-timer is set in heat operation and
cool operation, operation starts before 0 to 30
minutes(depends on the room temperature) so
that preset temperature is obtaind at set time.
7-2 ONE-HOUR TIMER
When ONE-HOUR timer is set, the unit turns off
automatically after one hour. The one hour timer
operation has priority over other time operation,
such as the TIMER ON and TIMER OFF. If the
ONE-HOUR TIMER button is pressed again
during operation, the unit will operate additionally
for another one hour.
8. Automatic air conditioning
When automatic air conditioning is selected, the
operation mode and preset temperature are set
automatically according to the room temperature on
