About the SLEEP Timer
To prevent excessive cooling during sleep, the SLEEP timer function automatically modifies the thermostat setting in accon-
dance 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 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.
SLEEP timer setting
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.
