Protection Control For Cooling & Soft Dry Operation
15.2.1 Outdoor Air Temperature Control
•
The compressor operating frequency is regulated in accordance to the outdoor air temperature as shown in the
diagram below.
•
This control will begin 1 minute after the compressor starts.
•
Compressor
frequency will adjust base on outdoor air temperature.
15.2.2 Cooling Overload Control
•
Detects the Outdoor pipe temperature and carry out below restriction/limitation (Limit the compressor Operation
frequency).
•
The compressor stop if outdoor pipe temperature exceeds 61°C (E7/9/12/15PK), 63°C (E18/21PK), 65°C
(E24/28PK).
•
If the compressor stops 4 times in 20 minutes, Timer LED blinking (F95 indicated: outdoor high pressure rise
protection).
15.2.3 Freeze Prevention Control 1
•
When indoor heat exchanger temperature is lower than 0°C continuously for 6 minutes, compressor will stop
operating.
•
Compressor will resume its operation 3 minutes after the indoor heat exchanger is higher than 5°C.
•
At the same time, indoor fan speed will be higher than during its normal operation.
•
If indoor heat exchanger temperature is higher than 5°C for 5 minutes, the fan speed will return to its normal
operation.
15.2.4 Freeze Prevention Control 2
•
Control start conditions
o
During Cooling operation and soft dry operation
During thermo OFF condition, indoor intake temperature is less than 10°C or
Compressor stops for freeze prevention control
o
Either one of the conditions above occurs 5 times in 60 minutes.
•
Control

o
Operation
stops
o
Timer LED blinks and “H99” indicated
15.2.5 Dew Prevention Control 1
•
To prevent dew formation at indoor unit discharge area.
•
This control will be activated if:
o
Outdoor air temperature and Indoor pipe temperature judgment by microcontroller is fulfilled.
o
When Cooling or Dry mode is operated more than 20 minutes or more.
•
This control stopped if:
o
Compressor
stopped.
o
Remote control setting changed (fan speed / temperature).
o
Outdoor air temperature and indoor intake temperature changed.
•
Fan speed will be adjusted accordingly in this control.
