2. Basic Functions
2.1 Cooling
2.1.1 Operating conditions and procedures
a) Tinner amb ≥ Tpreset +1
o
C(2
o
F), cooling mode: compressor cycles on, fan motors will operate in set speed.
b) Tinner amb ≤Tpreset -1
o
C(2
o
F), compressor and outdoor fan motors cycle o󰀨, indoor fan motor will operate in set speed.
c) Tpreset -1
o
C(2
o
F) < Tinner amb < Tpreset +1
o
C(2
o
F), operates like before.
2.1.2 Temperature setting range is 16
o
C~30
o
C(61~86
o
F).
2.2 Fan Only
2.2.1 In Fan Only, compressor and outdoor fan motors cycle o󰀨, indoor fan motor will operate in set speed.
2.2.2 Temperature setting range is 16
o
C~30
o
C(61~86
o
F).
2.3 Heating
2.3.1 Heating conditions and process
a) When Tamb. ≤Tset+1
o
C(2
o
F), the unit starts heating operation. In this case, the 4-way valve, compressor and outdoor fan motors run
simultaneously; the indoor fan motor runs in cold air prevention condition.
b) When Tamb. ≥Tset+3
o
C(6
o
F), the compressor and outdoor fan motors stop; the 4-way valve remains energized; the indoor fan motor
blows resindooral heat;
c) When Tset +1
o
C(2
o
F) < Tamb. < Tset+3
o
C(6
o
F), the unit will maintain its previous running status.
2.3.2 Temperature setting range is 16~30
o
C(61~86
o
F).
2.4 Dehumidifying
2.4.1 Operating conditions and procedures
a) Tinner amb > Tpreset +2
o
C(4
o
F), operates in Cooling mode, fan motors will operate in low speed.
b) Tpreset -2
o
C(4
o
F)≤Tinner amb ≤ Tpreset+2
o
C(4
o
F), dehumidier is on, indoor fan motor will operate in low speed. Compressor and
outdoor fan motors will rstly on for 6 minutes and o󰀨 for 4 minutes and then cycle on and o󰀨.
c) Tinner amb < Tpreset -2
o
C(4
o
F), compressor and outdoor fan motors stop, indoor fan motor will operate in low speed.
2.4.2 Temperature setting range is 16~30
o
C(61~86
o
F).
2.5 Auto
2.5.1 Operating conditions and procedures
a) Tinner amb ≥26
o
C(79
o
F), cooling mode: Tpreset =25
o
C(77
o
F)
b) Tinner amb <22
o
C(72
o
F), if it is a Cooling and Warming controller, unit will operate in Warming mode, Tpreset = 20
o
C(68
o
F); if it is a
Cooling controller, unit will operate in Fan Only, Tpreset =68
o
F(20
o
C);
c) 22
o
C(72
o
F) ≤Tinner amb < 26
o
C(79
o
F), operates like before; if it is turned on for the rst time, it will operate in Fan Only.
3. Other Functions
3.1 Buzzer
When a controller is powered on or a signal is received from a remote controller or a button is pressed, buzzer will beep once.
3.2 Sleeping Mode
1. In cooling and dry mode:
1.1 When the initial set temperature is16-23°C(61~74°F),the temperature will rise 1°C(2°F) by every hour after sleep function is set;the
temperature will not change after rising 3°C(6°F) ;after running for 7hours,the temperature will decrease1°C(2°F) and it will not change
after that.
1.2 When the initial set temperature is 24-27°C(75~81°F),the temperature will rise 1°C(2°F) by every hour after sleep function is set;
the temperature will not change after rising 2°C(4°F) ;after running for 7 hours, the temperature will decrease 1°C(2°F) and it will not
change after that.
1.3 When the initial set temperature is 28-29°C(82~84°F),the temperature will rise 1°C(2°F) by every hour after sleep function is set;
the temperature will not change after rising 1°C(2°F) ; after running for 7 hours, the temperature will decrease 1°C(2°F) and it will not
change after that.
1.4 When the initial set temperature is 30°C(85~86°F) , the unit will keep on running at this temperature; after running for 7 hours, the
temperature will decrease 1°C(2°F) and it will not change after that.
2. In heating mode:
2.1 When the initial set temperature is 16°C(61~62°F), the unit will keep on running at this temperature;
2.2 When the initial set temperature is 17-20°C(63~68°F), the temperature will decrease 1°C(2°F) by every hour after sleep function is
set; the temperature will not change after decreasing 1°C(2°F);
2.3 When the initial set temperature is 21-27°C(69~81°F), the temperature will decrease 1°C(2°F) by every hour after sleep function is
set; the temperature will not change after decreasing 2°C(4°F);
2.4 When the initial set temperature is 28-30°C(82~86°F), the temperature will decrease 1°C(2°F) by every hour after sleep function is
set; the temperature will not change after decreasing 3°C(6°F);
3.3 Delay Timer
a) Timer On: when the air conditioner is o󰀨, it can be set automatically come on in 0.5h ~ 24h at its set mode.
b) Timer O󰀨: when the air conditioner is on, it can be set automatically turn o󰀨 in 0.5h ~ 24h.
