About TURBO function 

At the start of this function, the unit will blow at a super high speed to cool or heat quickly, so the room temperature 
approaches the preset temperature as soon as possible. 
 

UNIT DEFROSTING CYCLE 

While the unit is running in 

HEAT

 mode during colder weather, frost can build up on the outdoor coil. This is 

common on all heat pump units made by all manufactures. If the unit is running and the automatic defrost mode 
is enacted the indoor unit will stop running and display an 

H1

 code. Once the defrost cycle is finished and the 

outdoor coil is defrosted the indoor unit will start to run again in the mode that it was last set up for.

controller off and pressing the 

BLOW

MODE

 buttons simultaneously. You will see the symbol of 

H1

 

appear on the remote. To stop the defrost cycle simply press the 

BLOW

 and 

MODE

 buttons again and the 

H1

 

will disappear from the remote screen.
