8.3. Heating Mode Operation(Only for PA7DKD,PA9DKD)
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”
.

Deice Control
Deice operation is to protect the outdoor unit from freezing.
Normal Deice Operation
Deicing starts 30 minutes after heating mode operation or 60 minutes after the latest deicing operation. If temperature of
outdoor piping, tested by TRS, falls to -3 (TRS OFF) or below for continuously 50 seconds, deicing operation starts.
Overload Deicing Operation
During heating operation, if the accumulative stopping time of outdoor fan reaches 60 minutes,
deicing operation will start 1 minute after compressor starts.
Deicing operation ends under conditions below
(a) After 12 minutes.
(b) Temperature of outdoor unit rises to 4 .
(c) As the illustration showed bellow and due to Time Delay (Td), deicing won’t ends immediately.

Once deicing operation starts, it won’t end until 60 seconds later.
When deicing operation ends, compressor will stop for 30 seconds, and 4-way valve remains at cooling mode operation
for 10 seconds.
