Quietside QSVMI-09A, Service Manual

In cooling and fan mode, after setting sleep procedure 1h, Tpreset will increase 33.8 ; 2h later, Tpreset will increase 35.6 , 

then remain the temperature, Tpreset will not exceed 86 ; under heating, after setting sleep procedure 1h, Tpreset 

will decrease 33.8 ; 2h later, Tpreset will decrease 35.6 , then remain the temperature, Tpreset will not exceed 60.8 ; the 

setting temperature will not change under fan and auto mode. 

3.5 TIMER Function 

General timer: 

a.  TIMER ON: The timer on can be set when the unit is OFF, the controller will run under original    setting mode 

when the time of timer on reaches, the timer space is 0.5h, and setting range is 0.5-24h. 

b.  TIMER OFF: The timer off can be set when the unit is ON, the unit is OFF when the timer time reaches, the 

timer space is 0.5h, and setting range is 0.5-24h. 

Clock timer: 

a.  TIMER ON: If set timer on when the unit is running, it will goes to run; if set the timer on when the unit is off, 

the unit will run with the pre-setting mode when the time of setting timer on reaches. 

b.  TIMER OFF: If set timer off when the unit is off, when setting timer off, the unit will maintain stand-by status; if 

set timer off when the unit is on, when the time of setting timer off reaches, the system will stop to run. 

c.  TIMER changing: When the unit under timer status, it can set ON and OFF by remote control, and reset timer 

time, the unit will run under the last setting status. 

Set timer on and timer off together when the unit is running, the unit will maintain the current status, once the time 

of setting timer off reaches, the unit will stop to work. 

Set timer on and timer off together when the unit is off, the unit will maintain off status until the time of timer on 

reaches, the unit will start to work, hereafter the time of timer on reaches everyday, the unit will run under the 

original setting mode, and the unit stop to work when the time of timer off reaches. 

When the time of setting timer on and setting timer off is the same, the unit is off. 

3.6 Memory Function 

      Memory contents: mode, swing (up and down), light, set Temp., set fan speed, general timer (clock timer doesn’t 

memory) 

      The unit will on automatically with memory content after re-energized. 

      There is no setting timer function in the last remote control order, and the system memory the last remote control 

order and working under that setting method. 

   There is general timer function in the last remote control order, the system is energized before the timer time 

haven’t reach, the unit will memory timer function of the last remote control order after re-energized, and the timer time 

will star to calculate after re-energized. 

      There is timer function in the last remote control order, but the timer time reaches, the system will de-energize after 

timer on and timer off, after re-energized, the system will memory the running status which before power-off, and no 

timer action; the clock timer doesn’t memory. 

3.7 I FEEL Function 

If controller receives I FEEL command, it will run at the ambient temp sent by remote controller (but it will also run at 

sampling temp. of AC temp sensor itself except defrost and anti-cool air). The remote controller will send ambient temp 

to controller every 10min, so if the controller hasn’t received ambient temp from remote controller after 11min, it will run 

at temp. of AC itself. If this function is not set, all ambient temp will adopt sampling value of AC temp. sensor itself. 

3.8 Turbo Function 

The TURBO function can be set only under COOLING and HEATING mode, when controller receiving turbo order, the 

indoor fan motor will run with high speed, and send turbo signal and high speed to outdoor unit. 

3.9 Swing (up and down) Control 

 After energization, up & down swing motor will totate guide louver to position 0 to close air outlet. After turn on the unit,

if swing function has not been set,  up & down guide louver will clockwise turn to position D under heating mode, or 

clockwise turn to level position L1 under other modes. If the unit is turn on with 
swing function setting, guide louver will swing between L and D. There are 7 kinds

of swing states of guide louver. Position L,A,B,C,D, swing between L and D, stop
between L and D (included angle L and D is equiangular). Upon stop of unit, guide

louver will close to position 0. Swing action is valid only when swing command is

set and indoor fan is running.
