Technical Information

(8) I feel control mode

After controller received I feel control signal and ambient temperature sent by remote controller, controller will work according to the ambient 
temperature sent by remote controller.

(9) Compulsory defrosting function

(1) Start up compulsory defrosting function
Under ON status, set heating mode with remote controller and adjust the temperature to 16

. 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.

(10) Refrigerant recovery 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.

(11) Ambient temperature display control mode

1. When user set the remote controller to display set temperature (corresponding remote control code: 01), current set temperature will be 

displayed. 

2. Only when remote control signal is switched to indoor ambient temperature display status (corresponding remote control code: 10) from 
other display status (corresponding remote control code: 00, 01,11),controller will display indoor ambient temperature for 3s and then turn 
back to display set temperature.
Under  this  mode,  indoor  fan  operates  at  set  fan  speed.  Compressor,  outdoor  fan,  4-way  valve  and  electric  heating  tube  stop  operation. 
Indoor fan can select to operate at high, medium, low or auto fan speed. Temperature setting range is 16~30

O

C.

(12) Off-peak energization function:

Adjust compressor’s minimum stop time. The original minimum stop time is 180s and then we change to: 
The time interval between two start-ups of compressor can’t be less than 180+T s(0≤T≤15). T is the variable of controller. That’s to say 
the minimum stop time of compressor is 180s~195s. Read-in T into memory chip when refurbish the memory chip each time. After power 
recovery, compressor can only be started up after 180+T s at least.

(13) SE control mode

The unit operates at SE status. 

(14) X-fan mode

When X-fan function is turned on, after turn off the unit, indoor fan will still operate at low speed for 2min and then the complete unit will be 
turned off. When x-fan function is turned off, after turn off the unit, the complete unit will be turned off directly.

(15) 8º heating function

Under heating mode, you can set 8º heating function by remote controller. The system will operate at 8ºset temperature. 

(16) Turbo function

This function can be set in cooling or heating mode, but not in auto, drying or fan mode. Press fan button to cancel this function.
