Functions and control 
Domestic air conditioner 
7.1.3      Dehumidifying mode. 
* temperature control range: 16---30℃
* temperature difference:      ±1℃
Control feature: send the dehumidifying signal to the outdoor system.
When Tr>Ts+2℃, the compressor will be turned on, the indoor fan will operate at the set speed.
When Tr  is between the  Ts  and  Ts+2℃, the  outdoo
r system will  operate  at the high  dehumidifying
frequency for 10 minutes and then at the low dehumidifying    mode for six 
minutes. The indoor fan will
operate at low speed.
When Tr
< Ts, the outsystem will be stopped, the indoor fan will be stopped for 3 minutes and then
turned to the low speed option.
All the frequency converses have a  ±1℃  diff
erence.
* Wind speed control: Automatic:
When Tr≥ Ts+ 5℃, high speed. 
When Ts+3℃≤Tr< Ts+5℃, medium spee
d. 
When Ts+2℃≤Tr< Ts+3℃, low speed. 
When Tr<Ts+2℃, light speed. 
If the outdoor fan stopped, the indoor fan will be paused for 3 minutes. 
If the outdoor fan stopped for more than 3 minutes and the outdoor system still operates, the system 
will be changed into light speed mode. 
When the airflow speed has no delay from the high to low switching, the speed should be delayed for 
3 minutes (remain at high speed for 3 minutes.) before the next switch. 
Manual: When the sensor is off or  Tr< Ts+3℃, the manual  operation can  not be  made. (obligatory 
automatic operation.) 
*Airgate location control: the location for the airgate can be set according to your needs.
*Defrosting  function:  preventing  the  frosting  on  the  indoor  heat  exchanger  (when  cooling  or
dehumidifying). 
When the compressor works  continuously for 1/6 minutes  (adaptable in EEPROM)
and  the  temperature  of  the  indoor  coils  has  been  below  zero  centigrade  for  10  seconds,  the
compressor will be stopped and the malfunction will  be recorded in the malfunction list. The indoor
system will continue to run. When the temperature of the indoor coil is raised to 7℃, the compressor
will be restarted again (the requirement of 3 minutes’ delay should be satisfied.)
* Coil  protection  (synchronic  overheating  protection)  are  installed  for  the  four  directions  latch
malfunctions when 
dehumidifying.
* Timing system on/off function.
* Dormant control functio
n.
7.1.4      Heating operation mode. 
* temperature control range: 16---30℃
* temperature difference:      ±1℃
* control feature: the temperature compensation is automatically added and the system will send the
heating signals 
to the 
outdoor system.
If Tr≤Ts, the outdoor compressor is turned on, the indoor fan will be at the cold air proof mode.
If Tr>Ts+1℃, the outdoor system is turned off, the indoor fan will be at the heat residue sending mode.
