TIMER OPERATION

About the PROGRAM timer

●The PROGRAM timer allows you to integrate OFF timer and ON timer operations in a single sequence. The se- quence can involve one transition from OFF timer to ON timer, or from ON timer to OFF timer, within a twenty- four hour period.

●The first timer function to operate will be the one set near- est to the current time. The order of operation is indi-

cated by the arrow in the remote control unit’s display (OFF → ON, or OFF ← ON).

●One example of PROGRAM timer use might be to have the air conditioner automatically stop (OFF timer) after you go to sleep, then start (ON timer) automatically in the morning before you rise.

About the ON timer

●The timer function is designed to bring your room to a comfortable temperature by the set time; as a result, the unit automatically begins operation before the set time so that the room reaches the desired temperature by the time set on the timer (“Nice-Morning Timer”).

●The hotter it is in summer, or the colder it is in winter, the earlier that operation will begin.

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:

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.

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.
