About the SLEEP Timer
To prevent excessive cooling during sleep, the SLEEP timer function automatically modifies the thermostat setting in accord- ance with the set 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.
