◆
Memory content: ON status, mode, up&down swing, light, set temperature, set fan speed, general timer, Fahrenheit/ Centigrade
◆
General timer can be memorized. Timer will be recalculated from the time of energization.
◆
Clock timer can’t be memorized.

(12)I Feel function
When I FEEL command is received by controller, and also the ambient temperature is received from remote control, the controller will
operate according to the ambient temperature sent by the remote controller (For cold blow prevention, the unit operates according
to the ambient temperature sensed by the air conditioner). The remote controller will send ambient temperature data to the controller
for every 10 minutes. When the data has not been received for 11 minutes, the unit will operate according to the temperature sensed
by the air conditioner. If I FEEL function is not selected, the ambient temperature will be that sensed by the air conditioner. Ambient
temperature of I FEEL displayed by controller is 1 ~59°C.
(13)Health and Cold Plasma Function(Optional)
When the unit is operating, turn health or cold plasma to be ON/OFF by health button in remote control (if there is no such button in
remote control, the health is on as default). Only when health or cold plasma is turned on and indoor fan is operation, such function
can be activated.
(14)Static Dedusting Function(Optional)
When the unit is operating, turn static dedusting ON/OFF by health button in remote control (if there is no such button in remote
control, the health is on as default). Only when static dedusting is turned on and indoor fan is operation, such function can be
activated.
(15)Fahrenheit Display
Nixie tube displays current set temperature. If remote signal is Fahrenheit, the temperature will be displayed in Fahrenheit. The set
temperature range is 16~30°C. Under Auto mode, in COOL operation and FAN operation, 25°C will be displayed, while in HEAT
operation and FAN operation, 20°C will be displayed. For cooling-only controller, only 25°C will be displayed.
(16)Locked protection to Indoor Fan Motor
If the indoor fan motor keeps low rotation speed for a continuous period of time after startup, the unit will stop operation and
display“H6”.
(17)Mute Mode
①
Auto Mute: When selecting fan speed of auto mute, the fan speed will be adjusted according to change of ambient temperature;
when temperature meets the requirement of the setting, the unit will operate at lowest speed.
②
Mute mode: When selecting fan speed of mute, the unit will directly operate at lowest fan speed.
This position is start point
(18)Compulsive Defrosting Function
①
Start up compulsory defrosting function
Under ON status, set heating mode with remote controller and adjust the temperature to 16°C. Press “+, -, +, -, +,-” button
successively within 5s and the complete unit will enter into compulsory defrosting status. Meanwhile, heating indicator on indoor unit
will ON 10s and OFF 0.5s successively. (Note: If complete unit has malfunction or stops operation due to protection, compulsory
defrosting function can be started up after malfunction or protection is resumed.
②
Exit compulsory defrosting mode
After compulsory defrosting is started up, the complete unit will exit defrosting operation according to the actual defrosting result, and
the complete unit will resume normal heating operation.
(19)Refrigerant Recycling Function
①
Enter refrigerant recycling function
Within 5min after energizing (unit ON or OFF status is ok), continuously press LIGHT button for 3 times within 3s to enter refrigerant
recycling mode; Fo is displayed and refrigerant recycling function is started. At this moment, the maintenance people closes liquid
valve. After 5min, stick the thimble of maintenance valve with a tool. If there is no refrigerant spraying out, close the gas valve
immediately and then turn off the unit to remove the connection pipe.
②
Exit refrigerant recycling function
After entering refrigerant recycling mode, when receive any remote control signal or enter refrigerant recycling mode for 25min, the
unit will exit refrigerant recycling mode automatically If the unit is in standby mode before refrigerant recycling, it will be still in standby
mode after finishing refrigerant recycling; if the unit is in ON status before refrigerant recycling, it will still run in original operation
mode.
