When T amb≤Tpreset -1 , the unit will be stopped under cooling mode,℃ in which case the compressor and outdoor fan will be stopped and the indoor fan will run at preset speed. When Tpreset -1 <T℃ amb.< Tpreset +1 , the unit will maintain its original operating status.℃

6.1.2.2 Dehumidifying Mode 6.1.2.2.1 Dehumidifying Conditions and Process When T amb. Tpreset +2 , the unit will run under cooling mode, in which case the compressor and outdoor fan will be ℃started, the indoor fan will run at low speed. When Tpreset -2 ≤T℃ amb.≤Tpreset +2 , the compressor, and outdoor unit will run 6 minutes and stop 4 minutes in repeated ℃cycle, while the indoor fan will run at low speed.

When T amb.< Tpreset -2 , the c℃ ompressor and outdoor fan will be stopped. Indoor fan will run at low speed.

Under this mode, the switchover vlave can not be energized, and the temperature can be set within a range from 16

to 30 .The initial value is 25 .

Under this mode, the switchover vlave can not be energized, and the temperature can be set within a range from 16 to

If T amb.≥Tpreset +1 , the compressor and outdoor fan will be stopped, the switchove℃ r valve will remain energized and the indoor fan will stop after 10s when it runs at low speed.When Tpreset -1 <T℃ amb.< Tpreset +1 , the unit will maintain its original operating status.℃

Under heating mode, the temperature can be set within a range from 16 to 30 . The initial value is 25 .℃ ℃ If the unit is switched off under heating mode or switched from heating mode to another mode, the 4-way valve will be de-energized after 2-minute lag.For the first startup of compressor , the exhaust protection will be shielded for 1 min.

6.1.2.5 AUTO Mode Under this mode, the system will automatically select its run mode (cooling, dehumidifying, heating or fan) with the change of ambient temperature. Once a mode is started, the unit will run at least 30 seconds before it can the run status under auto mode according to the ambient temperature. 6.1.3 Other Control 6.1.3.1 Sleep Function If the controller is under cooling or dehumidifying mode, the preset temperature will be increased by 1 one hour ℃

after running under sleep mode and will be increased by another 1 after two hours. The temperature will increased ℃

by 2 within two hours. After that, the unit will run at this temperature. ℃

6.1.2.3 Heating Mode (no this mode for cooling only unit)

When T amb.≤Tpreset -1 , the unit will run under heating mode, in ℃ which case the switchover valve, compressor and outdoor fan will be started, while the indoor fan will run in 90s at most.
