The conditions and process of heating

When Tamb Tset 2 ,the system enters heating running, in this case, the reversal valve, compressor,

outer fan enter simultaneously running.The indoor fan will delay at most for 2min to run.

When Tamb Tset 4 ,the compressor and outdoor fan will stop, but the reversal valve is still with power on,

the indoor unit will run at setting fan speed for 60s then will stop .

When Tset 2 Tamb Tset 4 ,the unit will maintain its original operating status.

Under this mode, the switchover valve will be powered on and the setting temperature range is 16-30 .

Anti-high temperature protection

Other protection

The other protections are the same with that under Cool mode.

Under dehumidifying and cooling mode, i f it is detected that the system is under antifreeze protection, the compressor and

and outdoor fan will be stopped, and the indoor fan will run at low speed. When antifreeze protection is released and the

the compressor has stoppedfor 3 minutes, the complete unit will resume its original operating status.

Upon meeting "run 6 mins and stop 4 mins" dehumidify condition, if it is detected that the system is under antifreeze
