About the SLEEP timer
To prevent excessive warming or cooling during sleep, the SLEEP timer function automatically modifies the thermostat set- ting in accordance with the time setting. When the set time has elapsed, the air conditioner completely stops.
*During Heating operation:
When the SLEEP timer is set, the thermostat setting is automatically lowered 1 °C every thirty minutes. When the thermostat has been lowered a total of 4 °C, the thermostat setting at that time is maintained until the set time has elapsed, at which time the air conditioner automatically turns off.
During Cooling/Dry operation:
When the SLEEP timer is set, the thermostat setting is auto- matically raised 1 °C every sixty minutes. When the thermo- stat has been raised a total of 2 °C, the thermostat setting at that time is maintained until the set time has elapsed, at which time the air conditioner automatically turns off.
