It’s applicable for recreational vehicle air conditioner.
2 Basic functions
2.1 Cooling mode
1. Working condition and process of cooling operation
a) When Tinner amb.≥Tset+1°C(2°F), the unit operates under the
cooling mode.
Meanwhile, the compressor is turned on and the fan operates at
the set fan speed.
b) When Tinner amb.≤Tpreset-1°C(2°F), the compressor stops
operation and the indoor fan operate at the set fan speed.
c) When Tset-1°C( 2°F)
＜
Tinner amb.
＜
Tpreset+1°C(2°F), the
unit keeps previous operation status.
2.Under this mode, the temperature setting range is
16°C~30°C(61°F~86°F).
2.2 Fan mode
1. Under the fan mode, the compressor and the outdoor fan stop
operation. The fan operates at the set fan speed;
2. Under this mode, the temperature setting range is
16°C~30°C(61°F~86°F).
2.3 Heating mode
1. Working condition and process of heating operation
a)When Tinner amb.≤Tset+3
℃
(6°F), the unit operate under
heating mode. The 4-way valve, the compressor and the outdoor
fan operates and then indoor fan operates at the condition of cold
air prevention.
b)When Tinner amb.≥Tpreset+5°C(9°F), the compressor and
the outdoor fan stops operation and then 4-way valve keeps
energization. Indoor fan blows residual heat.
c)When Tset+3°C(6°F)
＜
Tinner amb.
＜
Tset+3°C(9°F), the unit
keeps previous operation status.
d) When Toutdoor amb.
＜
-5°C(23°F), the complete unit is not
allowed to enter into heating mode.
2. Under this mode, the temperature setting range is
16°C~30°C(61°F~86°F).
2.4 Dry mode
1. Working condition and process of dry operation: same as cooling
mode
2. Under this mode, the temperature setting range is
16°C~30°C(61°F~86°F).
2.5 Auto mode
a) When Tinner amb.≥26°C(79°F), the unit operates under cooling
mode. Tset=25°C(77°F)
；
b) When Tinner amb.≤22°C(72°F), if it’s the heat pump controller,
the unit operates under heating mode and Tset=20°C(68°F); if it’s
the cooling only controller, the unit operates under fan mode and
Tset=20°C(68°F)
；
c) When 22°C(72°F)
＜
Tinner amb.
＜
26°C(79°F), the unit keeps
original operation status. If the unit is energized for the rst time,
the unit operates under the fan mode.
3 Other function
3.1 Buzzer
When the controller is energized or receiving the signal of remote
controller or buttons, the buzzer gives out a sound.
3.2 Sleep
1. Cooling/dry mode:
a) When the initial temperature setting is 16°C~23°C(61°F~74°F),
after turning on the sleep function, the temperature will increase
1°C(2°F) every one hour. The temperature will keep the same after
it has been increased by 3°C(6°F). When the unit has operated for
7h, the temperature will decrease 1
℃
(2°F) and then the unit will
operate at this temperature all the time.
b) When the initial temperature setting is 24°C~27°C(75°F~81°F),
after turning on the sleep function, the temperature will increase
1°C(2°F) every one hour. The temperature will keep the same after
it has been increased by 2°C(4°F). When the unit has operated for
7h, the temperature will decrease 1°C(2°F) and then the unit will
operate at this temperature all the time.
c) When the initial temperature setting is 28°C~29°C(82°F~84°F),
after turning on the sleep function, the temperature will increase
1°C(2°F) every one hour. The temperature will keep the same after
it has been increased by 1°C(2°F). When the unit has operated for
7h, the temperature will decrease 1°C(2°F) and then the unit will
operate at this temperature all the time.
d) When the initial temperature setting is 30°C(85°F~86°F), the unit
operate at this temperature. When the unit has operated for 7h, the
temperature will decrease 1°C(2°F) and then the unit will operate
at this temperature all the time.
2. Heating mode:
a) When the initial temperature setting is 16°C
(61°F~62°F), the
unit operate at this temperature all the way.
b) When the initial temperature setting is 17°C~20°C(63°F~68°F),
after turning on the sleeping function, the temperature will decrease
1°C(2°F) every one hour. When the temperature has decreased for
1°C(2°F), the unit will operate at this temperature all the time.
c) When the initial temperature setting is 21°C~27°C(69°F~81°F),
after turning on the sleeping function, the temperature will decrease
1°C
(
2°F) every one hour. When the temperature has decreased for
2°C(4°F), the unit will operate at this temperature all the time.
d) When the initial temperature setting is 28°C~30°C(82°F~86°F),
after turning on the sleeping function, the temperature will decrease
1°C(2°F) every one hour. When the temperature has decreased for
3°C(6°F), the unit will operate at this temperature all the time.
3.3 Timer function
The unit can be set to be turned on or turned o at a certain time.
The precision is minute. Eg: Turn on the unit at 8:00am; turn o the
unit at 17:30pm.
a)Timer ON: If set timer ON when the system is operating, the
system continues to operate; if set timer ON when the system is
under o status, when the time for timer ON is reached, the system
