7.CONTROL MODE
33
The control unit selects a run mode according to the temperature difference between the room temperature and
temperature setting.
5.2 When the room temperature is above 2 higher than the temperature setting, the system runs in the cooling mode.
5.3 When the difference between the room temperature and temperature setting is equal to or lower than 2 , the
system starts in the dehumidification mode. In the dehumidification mode, both the compressor and outdoor fan
operate in the cycle of 10 minutes run and 6 minutes stop.
5.4 When dehumidification, the outdoor fan starts or stops as soon as the compressor starts or stops.
6. Heating mode (only applicable to the model with the heat pump type for cooling and heating)
6.1 In the heating mode, the temperature setting is determined with the remote
controller. The temperature control ranges from 16-30 .
6.2 When powered on for the first time, the compressor may be started immediately. After turning off, the compressor
must not be restarted until at least 3 minutes later.
6.3After turning on, the compressor must operate at least 5 minutes.
6.4 When the air conditioner turns off, the compressor is interrupted; the outdoor 4-way valve turns off after a 1
minutes and 40 seconds delay; and the indoor fan stops after a 40 seconds delay to blow out the residual heat.
6.5 Cold air prevention function. When the air conditioner turns on, the indoor unit does not start immediately. When
the heat exchanger temperature rises above 28 , the fan operates at the ultra-low fan speed, and the flap is
opened to the position 1; when the heat exchanger temperature 38 or runs for over 4 minutes, the fan runs at
a preset fan speed, and the flap is opened to a preset position. When the indoor heat exchanger temperature drops
below 23
, the indoor fan stops.
6.6 When the unit is running, the indoor fan stops 40 seconds after the compressor is interrupted because the room
temperature has reached the temperature setting. When the compressor is in operation again, the cold air
prevention function still works.
6.7 In the heating mode, the outdoor fan starts or stops as soon as the compressor starts or stops unless the indoor heat
exchanger overheat protection starts.
6.8 After being set to cooling only type in EE, the heating mode does not work.
6.9 The 4-way valve is activated.
