
This control will begin 1 minute after the compressor starts.

Compressor frequency will adjust based on outdoor air temperature.
13.11 Cooling Overload Control

Pipe temperature limitation / restriction.
o
Detects the outdoor pipe temperature and carry out restriction / limitation below (Limit the compressor
operation frequency)
o
The compressor stops if outdoor pipe temperature exceeds 61°C (S9PK), 63°C (S12, 18, 24, 28PK).
o
If the compressor stops 4 times in 20 minutes, Timer LED blinks (“F95” indicated: Outdoor high pressure rise
protection)
