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 Heating operation (HEAT & COOL MODEL (Reverse cycle) only):
When the SLEEP timer is set, the thermostat setting is automatically lowered 2 °F every thirty minutes. When the thermostat has been lowered a total of 8 °F, the thermostat setting at that time is maintained until the set time has elapsed, at which time the air conditioner automatically turns off.
