command of such a remote signal.
3.2 Operator-machine communication
1. The air conditioner has a thermal sensor to detect room temperatures. Some remote controller is
equipped with a thermal sensor (Such remote controller has the function of man-machine communication.
For details, refer to the section for the remote controller). In addition, there is a thermal sensor at the
indoor air inlet. In the case where the remote controller is equipped with a thermal sensor, the default
setting for room temperatures is subject to the detection by the remote controller. The remote controller
detects the room temperature once every 20 seconds, and automatically transmits a signal at an interval
of 3 minutes or when a change in the room temperature is detected. If the indoor control unit has not
received a remote signal for more than 10 minutes, the control function will be automatically switched
over to the thermal sensor on the indoor unit.
2. Neither the turning on nor turning off operation will cancel the operator-machine communication function.
3. In default, the air conditioner is set to start the operator-machine communication function.
3.3 Timer function
1. Timer on: When set to start in a time by the remote controller, the air conditioner starts in the timer on
condition. When the set time is up, the air conditioner will turn on and operates in the preset conditions
after receiving a signal from the remote controller. If the air conditioner has not received a signal from the
remote controller when the set time is up, it will automatically start and operate in the preset conditions.
2. Timer off: When set to stop in a set time by the remote controller, the air conditioner will start in the timer
off condition. When the set time is up, the air conditioner will turn off after receiving a signal from the
remote controller. If the air conditioner has not received a signal from the remote controller when the set
time is up, it will turn off automatically.
3. Neither the turning on nor turning off operation will cancel the timer function (Some remote controller has
a simple one-hour timer off function and excludes this operation).
3.4 Sleep
1. In the heating, cooling or dehumidifying mode, press the “Sleep” button on the remote controller to start
or cancel the sleep function in turn, and at the same time the sleep icon on the display screen will be on
or off accordingly.
2. In the heating mode, the set temperature will decrease by 3 one hour after the sleep function is
℃
started. After 2 more hours operation, the temperature decreases by 4 further. (except for the single
℃
cooling unit)
3. In the cooling mode, the set temperature will rise by 1 one hour after the sleep function is sta
℃
rted.
4. In default, the setting is to cancel the sleep function. Turning off the unit will also cancel the sleep
function.
5. The sleep function is valid for 8 hours. The air conditioner will turns off and cancel the sleep function after
the sleep function works for 8 hours.
3.5 High efficient run function
In the heating (except for the cooling-only unit), cooling or dehumidifying mode, it may be set for high
efficient run with the indoor fan speed changed to the high efficient fan speed and the compressor
operating at the highest frequency as available. If the display screen can display the frequency, the
