13.1.5.

Compressor Overheating Prevention Control

Instructed frequency for compressor operation will be regulated by compressor discharge temperature. The changes of frequency
are as below figure.
If compressor discharge temperature exceeds 112

q

C, compressor will be stop, occurs 4 times per 20 minutes, timer LED will be

blinking (“F97” is to be confirmed).

13.2. Protection Control For Cooling & Soft Dry Operation

13.2.1.

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.
