                   Domestic air conditioner 

 

Entering ‘mute’, you can have normal operation or signal control such as timing to finish the strength 
operation. 
When the system is at the automatic option with the strength/ mute function, if the system enters the 
cooling mode, the cooling strength/ mute function will be offered; if the system enters the heating 
mode, then the heating strength/ mute function will be offered; if the system enters the airflow mode, 
there will be no strength/ mute function. 
 

7.1.6  Mute operation 

The system enters the mode after receiving the ‘mute signal’. 
a. Mute heating: the airflow speed is slight, the system sends the mute signal to the outdoor system. 
b. mute cooling: the airflow speed is slight, the system sends the mute signal to the outdoor system. 
When the compressor operates, the airflow speed is mute speed. EEPROM is adaptable. 
Mute operation can not work under the dehumidifying and airflow-sending operation. 
 

7.1.7  Air refreshing 

After receiving the signal from the remote control, (HV series: the background light of the ‘health’ logo 
is green. HS series: the ‘health’ indicator will be lighted). If the fan operates, the Nano-Aqua operates 
to realize the ions sending function. 
If the indoor fan stops, the Nano-Aqua is turned off. 
When the Nano-Aqua is turned off, if the air refreshing system is turned on, the Nano-Aqua will be 
turned on when the fan operates. 
 

7.1.8  Timing 

You can set 24 hours’ on/off timing accordingly. After the setting, the timing indicator will be lightened. 
Also, the light will be turning off after the timing is finished. The followings are several timing methods. 

1.system /on timing:

 The timing indicator will be lightened and the indoor system is under the waiting 

mode. The light will be turned off when the timing is finished and the rest of the system will operate 
under a normal condition. The timing starts since the last reception of the timing signal. 

2.system /off timing:

 When the system is turned on, the timing indicator is lightened, the rest of the 

system will operated under a normal condition. When set time comes, the indicator light will be turned 
off and the system will be turned off. If you have set the dormant functions, the order of your settings 
will be operated according to the timing settings. 

3 .system /on and off timing: 

The settings will be completed according to the orders.. 

7.1.9  Dormant operation

 

The dormant timing is an eight hours unadaptable one. The timing signs are shown on the V series 
board. (RC series show the dormant signal, the timing light is lighted on the 6 lights board). 
2.1 Under the cooling/ dehumidifying operation, after the setting of the dormant operation, the set 
temperature will be raised for 1 centigrade after 1 hour’s operation and will be raised for 1 centigrade 
1 hour later. The system will keep this status for 6 hours and then close. 
2.2 Under the heating mode, after the setting of the dormant operation, the setting temperature will fall
