CONTROL SYSTEM 12.8.4 Compressor over Heating Protection The Discharging temperature is used as the compressor’s internal temperature. If the discharge temperature rises above a certain level, the operating frequency upper limit is set to keep this temperature from going up further. Compressor frequency will be reduced when CTT reaches above 97C Compressor will stop when CTT reaches 110C If the unit stops as such protection for 6 times...
