Electronic controller:
1.Automatic mode
1) Initial RT determines the working mode and ST,the mode is determined effective only once unless
A/C shut-down then re-started. If from other modes switches to autoamatic mode (including mode
conversion after shutdown), it should be that the compress stop more than 3 min then temperature
judgement and automatic mode are conducted (it can conduct immediately from fan mode switched
to automatic, the indoor fan stops, three minutes later the response is made and start up). Within 3
min, the output as: Showing the room temperature, indoor fans starts (or anti-cold airflow), the
outdoor fan stops;
2) With memory controller, once being turned off or in case of an accidently power cut, the A/C is able
to retain and restore the original mode when being turned on or the power supply is resumed, if the
auto restart function activated. power-down after power-on; while if the auto restart fundction isn’t
activated, the A/C enters standby state.

Under automatic mode (including from automatic converted into dehumidifying Dry mode), when the
temperature up and down signals from the remote controller is received, the setting temperature ST
adjusts correspondingly to the current room temperature plus or minus 1℃, the automatic regulating
temperature range is ± 2℃.
2．Cooling mode
1) The control of the compressor
a. When RT－ST≥1℃，the compressor is running.
b. When RT－ST＜－1℃，the compressor is off.
c. When －1℃≤RT－ST＜1℃, the compressor keeps its original state.
2) Outdoor fan motor and the compressor run simultaneously (except for defrosting).
3) The control of indoor fan motor:
a. Indoor fan motor can operate by automatic, low, middle, and high airflow speed circularly.
b. Indoor fan motor’s the automatic airflow speed control Indoor fan motor can operate by automatic，

When the temperature changes lead to changes in airflow speed, the switch can only be made
orderly, and every grade of air flow speed runs 1 minute at least.
