Heating Mode Operation(Only for PA12DKD)

When selecting the Heating Mode Operation, the unit will operate according to the setting by the Remote Controller and

the operation is as the following.

Time Delay Safety Control

Over Load protection Control

When temperature of indoor heat exchanger rises to 51

, outdoor fan will stop

when temperature of indoor heat exchanger falls to 49

, outdoor fan will restart.

When temperature of indoor heat exchanger rises to 65

or above, compressor stops, and will restart 4 minutes later.

4-way valve control

Anti-reversing Control

If the compressor stopped by switching off, turning off by remote controller, or power off, it will not restart within 3 minutes.

When room temperature reaches the set temperature on the remote controller, compressor stops and will not restart within

4 minutes.

3 minutes after the compressor stopped, indoor fan will stop for 1 minute. Then indoor fan will resume operation with the

speed at ”super low”

T= intake air temperature - evaporator temperature

If the compressor has been continuously running for 5 minutes or longer, and the difference of temperature between

intake air and evaporator is continuously lower than 5.0

or below for 2 minutes, the compressor will stop , and then

restart 3 minutes later.(Time Delay Protection Control is effective.)

During heating mode operation,4-way valve is at

open
