Electrical Control Function   
96  Electrical Control System 
from follow-me signal every 3 minutes. 
3)  The  PCB  will  take  action  to  the mode  change  information  from  remote  controller  signal,  and  the 
follow-me function will be turned off. (if the wired remote controller does not initiate follow me function). 
4)  When the unit is running with follow-me  function,  if  the PCB  doesn’t receive any signal from remote 
controller for 7 minutes or pressing FOLLOW ME button again, the follow-me function will be turned off 
automatically, and the temperature collection function of room temperature sensor will be available, the 
PCB will control the unit according to the room temperature detected from its own room temperature 
sensor and setting temperature. 
5)  When the  indoor PCB  receives the  follow-me signal from wired remote  controller,  the control  is the 
same  as that  from wireless  remote controller,  but  buzzer will not  respond. When  the PCB  receives 
turning-off follow-me signal from wired remote controller, the unit will quit follow-me function at once. 
The follow-me function controlled by wired remote controller prevails that by wireless remote controller. 
1.3.13 8℃  Heating(optional) 
In heating operation, the preset temperature of the air conditioner can be as lower as 8℃, which keeps the 
room temperature steady at 8℃  and prevents household things freezing when the house is unoccupied for 
a long time in severe cold weather. 
1.3.14 Mode conflict

(2) Unit action 
  In case of one Indoor unit working in cooling mode or fan mode, and another indoor unit is set to heating 
mode, the indoor unit working in cooling mode or fan mode will change to off. The outdoor unit will 
change to heating mode after compressor stop 3 minutes. . 
  In case of one Indoor unit working in heating mode, and another indoor unit is set to cooling mode or fan 
mode, the indoor unit setting to cooling mode or fan mode will change to stand by. The outdoor unit will 
continue working in heating mode. 
If heating mode stops (not including the indoor unit in heating mode reaching the set temperature), 3 
minutes after the outdoor unit restarts and works in cooling mode or fan-only mode. 
1.3.15 Point Check Function 
There is a check switch in outdoor PCB. 
Press the switch SW1 to check the states of unit when the unit is running.   
Press the  switch N times it  will display the  content corresponding to  No. N. After getting  into the  check
