About the SLEEP Timer
To prevent excessive warming or cooling during sleep, the SLEEP timer function automatically modifies the thermostat setting
in accordance with the time setting. When the set time has elapsed, the air conditioner completely stops.
During Cooling/Dry operation:
When the SLEEP timer is set, the thermostat setting is auto-
matically raised 2 °F every sixty minutes. When the thermo-
stat has been raised a total of 4 °F, the thermostat setting at
that time is maintained until the set time has elapsed, at
which time the air conditioner automatically turns off.
To Cancel the Timer:
Use the TIMER button to select "TIMER RE-
SET".
The air conditioner will return to normal op-
eration.
To Stop the Air Conditioner During Timer
Operation:
