6.2 Introduction of Basic Mode Function
1 Cooling mode
Cooling condition and process
When
Tamb.≥Tpreset+1ć(2), the unit operates in cooling mode. Meanwhile, compressor, draw water motor start operation. Indoor
fan operates at set fan speed. If indoor fan operates at high fan speed or middle fan speed, outdoor fan operates at high fan
speed. If
indoor fan operates at low fan speed, outdoor fan operates at low fan speed.
When
Tamb.≤Tpreset-1ć(2), compressor, outdoor fan and draw water motor stop operation, while indoor fan operates at set fan
speed.
Tp
reset-1ć(2)<Tamb.<Tpreset+1ć(2), the unit keeps original operation status.
Under this mode, 4-way valve is de-energized.
The temperature setting range is 16-30ć(61-86).
2 Dry mode
Drying condition and process
Under this mode, set temperature and ambient temperature won’t be displayed. Indoor fan operates at low fan speed. Compressor,
outdoor fan and draw water motor operates continuousl
y.
3 Heating mode
Working conditions and process for heat pump unit
When
Tamb.≤Tpreset+3ć(6), the unit operates in heating mode. Meanwhile, 4-way valve, compressor operates, and indoor fan
operates
at cold air prevention condition; if indoor fan operates at high fan speed or middle fan speed, outdoor fan operates at high fan
speed. If indoor fan operates at low fan speed, outdoor fan operates at low fan speed.
When
Tpreset+3ć(6)<Tamb.<Tpreset+5ć(10), the unit keeps original operation status,
When
Tamb.≥Tpreset+5ć(10), compressor and outdoor fan stop operation simultaneously. 4-way valve stop operation after the
compressor has stopped for 2 minutes. Indoor fan operates at blowing residual heat conditioner.
Under this mode, the temperature setting range is 16-3
0ć(61-86).
Working conditions and process for electric heating ty
pe unit
When
Tamb.≤Tpreset+3ć, the unit enters heating operation. In that case, electric heater starts up and the indoor fan operates at
setting speed;
When
Tpreset+3ć˘Tamb.˘Tpreset+5ć,the unit will keep its original status.
When
Tamb.≥Tpreset+5ć, electric heater will be turned off and indoor fan will stop after it operates at low speed for 60s.
Th
